My week with Samsung’s Gear VR


Gear VR review 05

Samsung and Oculus first unveiled the Gear VR Innovator Edition roughly a year ago, and I was super excited to try it. However, the price was quite steep and it only worked with the Galaxy S6 and S6 Edge, and the other model only worked with the Galaxy Note 4. For those reasons, I did not buy it. Having said that, I still wanted one really badly. I had been using a Google Cardboard and enjoyed the experience but had read a ton of good reviews talking about just how much better the Gear VR experience is. Finally, Samsung and Oculus made a VR headset that works with any of the of Samsung’s 2015 flagship flagships, and the price is only $99. Both of the problems I had before are now gone. So I decided to buy one for myself.

As I just said, I bought this myself. I also purchased a Galaxy S6 Edge myself, and used it to try the new Gear VR, Samsung didn’t supply either to me for testing. This is what I think will make my review a little more authentic from others around the internet. I am a real consumer using this for the first time, and will be sharing my first impressions and long-term use with the Gear VR. The review is written as I experienced it, and near the end is some cons, and conclusion of if I think you should get one or not.

First Impressions

Gear VR review 01

First things first, the box. To get the price point to only $99, Samsung had to do some major cuts. The box looks OK, but it’s nothing special to look at, and inside is just a cheap piece of plastic holding the Gear VR. The cheapness of the box doesn’t really matter, but they also took out a case and cleaning cloth that was supplied with the Gear VR Innovator Edition. Again, not the biggest deal, but considering Samsung wants you to bring the Gear VR around with you, it’s kind of hard to do that without a case. You’ll also need to buy a cleaning cloth yourself to keep everything clear. I think Samsung should of at least included one.

Gear VR review 02

It’s made completely out of plastic, but doesn’t feel that cheap. It’s very hard and feels pretty strong. It’s all white with black accents, which I think makes it look pretty cool. I can’t see myself wearing it, obviously, but I just assume I look like a Star Wars Storm Trooper, which heavily adds to the coolness.

It comes with straps as well — a side strap that wraps around your head and a top strap that goes over it. You don’t really need the top strap for it to stay attached to your face, but I recommend wearing it to allow for more even pressure on your face. It also raises the side strap up a little, which makes it easier to put on. The side clips are even on an angle, so they ideally want you to do this.

Design

I just touched on it a bit above, but there are some other areas that are important to talk about. The size of the device is not that big, so you don’t need the top strap to wear it; however, the main reason I recommended wearing it is because after prolonged use, you will definitely notice there is something on your face without it. The top strap really helps take away some of the pressure you will feel on your cheeks. It doesn’t totally get rid of it, but definitely helps.

Gear VR review 03

There are also buttons on the side that allow you to use the Gear VR while playing games, watching movies, and more. There are pretty much only three buttons, all located on the right side of the device. (Sorry left handed people.) There is a back button, a trackpad, and volume buttons. The volume and back buttons should be pretty self explanatory as to what they do, but the trackpad needs some talking about. It looks like a “plus sign” (+) and allows you to feel where to swipe up or down, or left or right. There is also what looks to be a button in the center, but it’s not clickable. And, finally, there is a wheel for focusing on top.

I think overall it looks cool, and after using it, the button placement works pretty well. The only complaint I have is with the back button. You are used to swiping with the trackpad all the time, but when you have to hit the back button it makes a clicking noise. It kind of takes away from the unified VR experience. Also, the + style trackpad is kind of pointless. Who doesn’t know the difference between up or down, and left or right, and needs a guide to tell them? Probably would of been better to just make a flat trackpad with no marks in it that you make gestures on. This way they could of had two finger swipe to go back instead of a button, and added possibly other gestures to make the VR experience even better. Not to mention the entire track pad is basically a touch sensitive button, so you can’t even search for the arrow indents since it will click something the second you touch it anywhere.

Setup

Once you take it out of the box and look at the device, it’s time to actually try it out. It works with more phones, but only Samsung flagships like the Galaxy S6, Galaxy S6 Edge, Galaxy Note 5, and Galaxy S6 Edge+. I believe the upcoming Galaxy S7 and its variants will work with it too, but I can’t say for sure at this time since they aren’t even publicly known.

Gear VR review 04

Anyways, to get the Gear VR to work you need to take off the front cover and plug your phone into the micro-USB spot. One thing that is disappointing is you can’t use a case on your phone to do this. I have the thinnest, cheapest see-through case on my Galaxy S6 Edge and even that was too big. You must take the case off before using it every time, which does become annoying after a while. Once you do that, and plug it in, a few beeps will be heard and it will tell you to remove your phone from the Gear VR. Once you remove your phone, it will prompt you to download the Oculus Store and a few Oculus apps. They aren’t huge, but you’ll need some space as some apps are over 100mb in size. And once everything has been downloaded, plug the phone back in to start your virtual reality experience.

One tip is always remember to unlock your phone first before plugging it into the Gear VR. You have to do this every time, and you don’t want to forget because it will force you to take your phone out, unlock it, then plug it back in. Memorize that you need to unlock it first now, so you don’t forget later. Trust me, it is super annoying having to take your phone out to unlock it when you forget.

Also, make sure to clean your phone with a microfibre cloth or on your shirt before putting it in. Any small pieces of dust will literally be magnified and ruin your viewing. It is mandatory your phone’s screen is perfectly clear.

Oculus Store

You can browse the Oculus Store in the Gear VR, or just on your phone. I recommend downloading any games or apps you want on your phone first, then playing them in virtual reality. Downloading in the Gear VR and browsing the store works pretty well, but takes a lot more power and battery life to do.

Gear VR Oculus Store

The store itself, whether it is in virtual reality or on your phone, is basically like the Play Store — side menu on the left, Must Haves, Top Selling, and other categories listed on the main page. There isn’t a messy flood of content, so you should have no problem finding any app you want. I will say since I first bought it, Samsung has added many new apps.

Many of the coolest apps are free, but games or more robust apps are paid. Prices range between $2-$15. I haven’t tried every paid app, but the pricing isn’t too bad for what you get. It’s hard to say $15 is too much for a game when that game is in virtual reality, while regular games for console systems are about $60, even the questionable ones.

What’s it like to use?

Actual use is very easy. You basically move your head to look at things and once the cursor is on what you want, tap the trackpad to select it. The Gear VR is very similar to using any computer, phone, tablet, only you move your head rather than your hand.

I can confirm the headset works with glasses. I have glasses and they fit fine. I let someone with larger, strangely shaped glasses try too, and they didn’t have any problems fitting them. I would imagine very large framed glasses might have trouble fitting though. The only thing I noticed is it pushes on them slightly and you might feel extra pressure on your nose. Also, if you have long eyelashes, you might feel them touch the glass when you blink. If this happens, they will sometimes smudge your glasses and you’ll have to take off the Gear VR to clean them. Not a huge deal, but just something to watch out for when putting them on if you also wear glasses.

There is a scroll wheel at the very top where you adjust your focus. Just follow the tutorial it shows you on setup to learn how to get the perfect focus. I tried with glasses on and off, and the focus wheel adjusted great for both. My eye sight is horrible, and I was surprised I could see clearly without my glasses on. Your eyes would have to be almost blind for the focus wheel not to work for you.

The real downside is the screen of your phone. Samsung uses Quad HD (2560×1440) displays, but even that isn’t enough. A 4K screen, at the very least, is going to be needed to truly give you a great experience. I would say Quad HD is the absolute minimum resolution to be decent because after a while any pixels you see will blend in once you get in to the content. But they are always technically there, and that heavily takes away from the experience. It’s not super horrible to look at, but there is room for improvement.

Its biggest pro is also its biggest con: the fact that it uses your phone. Notifications can just keep coming in. Luckily, there is at least an option to turn off notifications, which I recommend doing. I use mine mainly at night when my notifications are low, but having things pop up in front of you usually takes away from the virtual reality experience. All that said, you get true portability with no wires or anything else holding you back.

Testing Apps

Anyone who has tried virtual reality already knows it is pretty shocking. It might take a second or two to get used to, but once your eyes focus properly, it really does feel like you are in an entirely new environment.

I first tried the Oculus Movies app, which allows you to watch movies stored on your phone as well as Twitch streams, Facebook 360-degree movies, some movie trailers, and more. It just doesn’t show you all the movies on your phone. It only showed me ones that I took with the camera, and not others I had stored. I’m pretty sure you can move files around and store them in certain folders to be recognized, but I wish it just searched and showed you all of the movies right away. There are still other ways to watch movies without moving any files around too, just not in this particular app.

By far the coolest part about watching movies in this app is picking the environment you want to watch them in. You can pick between a home theater, movie theater, in the grass as an ant, plain  black, and, my favorite, the moon! They’re all cool, but the moon is just too sick. You see stars above you and the earth in the distance. The screen size changes slightly depending on the theater you selected, and I also found the moon’s to be the perfect size/distance away from you for easy viewing. The light from the movies even shines out and lights up elements of your environment just like it would in real life. It’s just awesome, I can’t explain it any other way. The biggest problem with it is lack of content. You have to have all the movies stored on your phone, and the current Samsung lineup doesn’t have a microSD card slot. Be prepared for storage space to be quickly destroyed once you start getting into virtual reality. Too bad they didn’t have a microSD card slot built in to the Gear VR; that would of made it so much better.

Gear VR Netflix

There are some apps that are coming out that allow streaming content, so you don’t have to use up all of your internal storage. Netflix has a standalone app, which is probably my favorite of them all. You can stream and watch anything from Netflix, and the controls make it even easier to use than most other systems I have tried. The big problem, though, is with screen size. It’s probably a 100-foot screen about 12-15ft away from you. It’s just too close and forces you to look around to see the entire thing. Also, I find it a little too low. You need to be sitting perfectly straight like a board to view it dead on. Hopefully Netflix will update the app and allow you to set the distance or screen size in the future. It’s watchable right now but could be better. Problems like this seem to be the theme of the Gear VR. Everything is pretty good but improvement is possible.

A web browser app exists, too. It’s actually really good. You use voice commands to search for things, and it understands what you are saying almost all the time. You can double tap to zoom in on text just like you can on a phone, and browse pretty much any site. This brings much more content to the Gear VR, and really opens up a lot of opportunities to come. It is made by Samsung, but I think it’s based off of Google Chrome. The reason for this is once it told me Chrome was out of date and I should update it. The only downside is the screen isn’t super sharp and reading text is slightly hard as it has blurry edges. It’s not impossible once you get used to it, but I’m pretty sure the browser was mainly a way of watching YouTube videos as there is no stand alone app otherwise.

Testing Games

I only tried one game as I didn’t want to pay to test others just yet, don’t judge me, but I couldn’t imagine the experience would be much different. The game I tried was Temple Run VR. I, and I am sure many of you, have played it on your phone before and should be familiar to how it works. I’m not a huge fan of playing it on my phone, but in virtual reality it is totally different. You swipe with the trackpad to move and use the headset to look around. It is much scarier seeing the shadow of a creature chasing you when it gets close, and the fact you can actually look around to see it makes it much more real. If you get motion sickness, you will probably feel it right away with this game. Personally, the sick feeling is almost wanted. If you were actually going super fast and running for your life, I’m pretty sure you’d feel sick too, which I think makes it feel more real. When you first start it feels as if you are going down a roller coaster. That pulled back into your seat feeling because you are going so fast forward. It’s weird not moving, yet still feeling as if you are. I got adjusted after a few minutes of playing and didn’t have any real problems with it. I liked it much more compared to the normal phone version.

For Temple Run you can swipe to move, but can also head to the options by pressing the back button and change the controls to lean your head to move, or look to move. Controls for gaming is a little tricky, but I like how this one at least gives you some options. You can also use a Bluetooth control for games, which I would recommend for more intense titles, but it’s not 100% needed. I didn’t have one around me to try, but I would assume it will feel more like playing a normal video game using one.

Sound

Sound is dependent on your phones speakers, or you can use a pair of headphones. A good pair of headphones will make a huge difference as your eyes and ears will be fully engaged in the content. However, I didn’t find the basic phone speaker to be too bad either. It’s right by your right ear, which is close enough to hear everything just fine in quiet environments, and somehow can be heard fairly evenly by both ears. I do wish Samsung cut a sound channel out of the plastic to funnel the sound towards you, but I think most people will use it with headphones anyways.

I used a pair of Bose in-ear headphones and some Sony DJ style headphones. Both worked great, but I liked the in-ear ones better as they don’t add any more weight to your head. Also, both connectors fit fine when plugging them in. My Bose headphone connector is fairly large and square, but had no issues fitting. I don’t think you will be able to use any L shaped connectors though.

Battery Life

All the coolness is starting to where off at this point, and we are getting to the real life ownership problems. Battery life isn’t the best on the Galaxy S6 Edge with normal use, and is pretty horrible using it with the Gear VR. Remember, even if you are watching a movie it still has to power a full 36-degree environment around you too. All of this computing power uses a ton of battery life.

To put it into perspective, I did a little test. I played a thirty-minute TV show on Netflix and checked how much battery that took. I charged my phone to exactly 50% and placed it into the Gear VR then went straight to Netflix. After watching one show I took out my phone and it had exactly 30% battery left. This was pretty consistent in use I found. About 20% every half hour. That means you can use it for roughly 3 hours before needing to charge it. However, that is if everything is perfect, real life consistent use will be much less, more like 2 hours. It’s probably a bit worse than if you were playing a regular intensive game on your phone. However, this is 2-3 hours of straight use, which you probably won’t be doing. This makes battery life not horrible, but you’ll have to have a charger near by because there is no way you can use it and still get a full day of use out of your phone.

Battery life isn’t actually as big of an issue as it sounds. It does have a charging port in the bottom of the device allowing you to charge your phone while in the virtual reality world. There are some major problems with this, however. Number one is I have heard you must use the supplied Samsung charger and that’s it. I haven’t tried other ones to confirm that, but that’s a huge downside. Also, you now have a wire attached and lose portability. The second reason, which is the main problem of the entire device is you won’t ever be able to charge it anyways. If you are playing any sort of virtual reality content for extended periods of time and charging your phone at the same time, be prepared to get an overheating message real quick. More on this later.

Real Life Use

The best part of the Gear VR compared to all other virtual reality options is it’s portable. All you need is your phone and the Gear VR. This is amazing, but there are some limitations.

You can’t just leave the house with your phone and the device. You will definitely need a battery pack to charge your phone too. As I said, you are looking at about two solid hours of use before needing to charge again. Plus, you’ll probably need a case so it doesn’t get damaged, and a cleaning cloth to make sure the lenses and your phone stays clean for optimum viewing.

The main issue with the Gear VR is overheating. You can’t just take your phone out, charge it, and go back to using VR. Your phone will be too hot and you’ll only get a few minutes before it tells you to stop and let it cool. This means after you charge your phone, which takes at least an hour with quick charge, you now have to sit and wait until it cools a little. Even being unplugging for a while and closing all the apps, I only managed about 20-30min of use before it tells me to take my phone out because it’s too hot. This makes playing games, and especially watching movies almost impossible. I tried to watch a 1.5 hour movie on Netflix and it took more like 3 hours with all the start and stopping. Again, I am using the Galaxy S6 Edge, you will probably get longer battery life if using the Galaxy Note 5 or Galaxy S6 Edge+ as their batters are larger. I have also heard they take a bit longer to overheat too, but it’s eventually gonna happen.

Some of you might be thinking I was using it in a hot environment, which would cause the phone to get hotter quicker. That would be a fair assumption, but I’m actually in Canada during December… It’s an ice box here. Yes, I am not testing it outside, but my house isn’t that hot either. If it overheats this quickly in winter, I can not imagine how quick it will heat up during the summer.

To give you an idea of temperatures, I used CPU-Z to test my phone before and after. The “exynos-therm” (chip) reaches about 70C and then the Gear VR will say your phone needs to take a break. Normal running usage of my Galaxy S6 Edge is about 35-40C. It basically doubles in temperature, and you will notice too as menus will start to lag. You have the option of dismissing the notification, but the warning is there for a reason. The last thing you want to do is burn out your phone.

I actually came back to this after a few more days of use and found a way to prolong the overheating message. Never change apps. Changing apps is the biggest cause of overheating quickly. If you plan on watching a movie, head straight to the movie, watch it, and leave the Gear VR. I managed to watch two thirty-minute TV shows on Netflix straight by doing this. I may have even been able to watch a third, but the second I left Netflix I got an overheating message. I was also in my basement where it is a bit colder, which may have helped. I have also heard this to be the case from other Gear VR owners I know.

If you really want to switch to a bunch of apps, the best way I have found to do this is put your phone in the fridge for about 5min. This will drop the temperature just enough to give you more viewing time. I have also heard people aiming a fan at their face while using it to keep it cool. You basically have to treat it like a hardcore gaming system.

Value

In the United States, the Gear VR is priced at $99; however, in Canada where I bought it, the Gear VR is priced at $160 with tax. This is a huge jump in price, and it’s actually more expensive than what the stores are selling last year’s Gear VR Innovator Edition for, and that used to be priced around $300 after tax here. I find it rather ironic that they are marketing this version as being an affordable alternative when last year’s version is selling for cheaper.

Even at the “cheaper” price, I don’t find VR to be that affordable. The reason I say that is because you have to buy a flagship Samsung only phone. My unlocked Galaxy S6 Edge (with tax) in Canada totals a bold $1,000. Now you have to pay $160 for the Gear VR, $10 per month for Netflix to watch movies and TV shows, and roughly $15 for a high-end game. All of this adds up to a pretty substantial investment just to watch things in virtual reality. Plus, once you dump your phone for a new one, you can basically toss all of this in the trash since it will never work again. At the same time, you have to pay to play. If you want to be the first to experience the latest and greatest, it’s gonna cost you. Can’t complain too much then.

Should I buy a Gear VR?

This section is really all that matters. Everything I’ve said gives you some reasons as to why you might want to look in to picking up the Gear VR. But for me, I’m on the fence. I have never bought a product and been so on the fence like I am with the Gear VR. On one hand, it is probably one of the coolest things I have ever experienced in my life. Yet the battery runs out or it overheats so quickly you can’t use it too much.

I really do like using the Gear VR, and think it’s pretty cool to watch movies on, but I originally wasn’t sure if I would be keeping mine. The fact that it overheats so quickly was the main reason. I think the problem was it was so new and I was switching between all the apps to try them out. This caused it to overheat a lot faster than normal. After a few days, I pretty much know what everything does and only go straight to the app I want. For this reason, if you already have a modern Samsung phone, I recommend picking one up. The mind-blowing experience it delivers trumps everything else, but be warned, when you first get it don’t switch to a bunch of apps right away to try them all out. This is a sure fire way to cause it to overheat and it will really frustrate you.

After about a full week of use I have had my pros and cons using it, but the coolness will be there every time I put it on. Also, new apps are added rather frequently and Samsung films live events you can tune in to. This gives me hope for the future of this product.

HTC One X9 is now available in China


HTC-One-X9-press-render

HTC, as promised, has finally made the One X9 official in the Chinese region, and it’s looks almost identical to the company’s new flagship, the One A9.

The HTC One X9 takes many design hints from the One A9, but there’s also been a lot of small design alterations, especially with the introduction of a new camera visor.

HTC’s new smartphone sports a 5.5-inch 1920 x 1080 IPS display, a MediaTek Helio X10 octa-core 2.2GHz processor, 3GB of RAM, 32GB of internal storage, and a microSD slot. It also has a 13-megapixel rear camera with Optical Image Stabilization (OIS) that can capture RAW images as well as well as shoot 4K video. Additionally, there’s a 5-megapixel front camera, as well as a non-removable 3,000mAh battery with fast charging.

The One X9 will sell for ¥2399 (USD$370) in the Chinese market, a significant step down from the One A9’s ¥2799 (USD$432) price point. It will be available in Gunmetal Grey and Silver color variations.

Unfortunately, there’s been no official word if this device will make it to European or Western markets.

Marshmallow rolling out for unlocked Motorola Moto G (2015)


motorola_moto_g_2015_multitasking_TA

On the heels of the Android 6.0 Marshmallow updates rolling out for the Motorola Moto X (2014), the smartphone maker continues to drop some holiday cheer in the way of operating system updates for their devices. This time, owners of the Motorola Moto G (2015) are the recipients as the Marshmallow update is rolling out to unlocked devices in the U.S. and Canada.

According to sources, the update will show up on unlocked, SIM-free handsets, although other variants should being getting the same update soon. For those with an unlocked device that has a SIM card installed, you may be able to try removing the SIM card to see if that triggers the option to receive Android 6.0 Marshmallow.

The update reportedly clocks in at about 2GB in size, so you will likely want to be on Wi-Fi to grab it. Once completed with the update process, your device should be on software version 24.11.25.en.US.

Like the Marshmallow update for the Motorola Moto X Pure Edition/Style and the Moto X (2014), the update for the 3rd generation Moto G brings all the expected Marshmallow changes as well as removal of a couple Motorola apps that became redundant. Marshmallow for the Moto X Play is also rolling out in a limited way – to the Canadian market – so expect to see that update start appearing in other markets as well.

HTC One X9 goes head to head with affordable Chinese phones


Even though it’s Christmas Eve, we’re getting used to seeing the odd product announcements coming from the Far East around this time of the year (ugh). Today, the culprit is none other than HTC, who has announced yet another metallic “hero” Android device, the One X9. Judging by its looks, you may as well say the Butterfly S (front) and Lenovo’s Phab Plus (back) made a baby here, especially with how the X9 even re-introduced HTC’s long-gone back-lit capacitive Android buttons. More interestingly, this device is going for just 2,399 yuan or about $370 off-contract in China, making it HTC’s most affordable hero device ever.

On paper, the X9 is pretty much what you’d expect from a premium mid-ranger these days, as it comes with a 5.5-inch 1080p display (likely IPS), an octa-core MediaTek X10 chipset (8x Cortex-A53), 3GB of RAM, 32GB of storage, a dedicated microSD slot (up to 2TB), a 3,000 mAh battery and dual Nano SIM slots. Radio-wise, you get the regular UMTS 3G (850/900/1900/2100) plus China Mobile’s TD-SCDMA 3G (1900/2000), along with dual-mode LTE (FDD bands 1/3/5/7/8/28; TDD bands 38/39/40/41).

Like the smaller but more expensive A9, the X9 is also garnished with a 13-megapixel f/2.0 main camera with optical stabilization plus dual-tone flash, as well as an UltraPixel f/2.0 front camera on the other side for better low-light shots; and yes, you can capture RAW images here. It’s worth pointing out that even though the A9 costs more than the X9, only the latter comes with BoomSound front-facing stereo speakers, thus making it a somewhat more attractive deal. What’s uncertain is whether the X9 will ship with Android 6.0, nor has HTC provided a date for pre-ordering or shipping.

At 2,399 yuan, this is HTC’s boldest attempt yet to steal a bigger slice of the pie from the likes of Xiaomi, Huawei, Oppo and Vivo who dominate that price tier in China. Having said that, these other brands still tend to offer slightly better specs at similar prices, so it’s up to HTC to market the X9 properly in that region. For the rest of us outside China, here’s hoping that we’ll get a similar bargain.

‘Rock Band 4’ devs will wipe the leaderboards next month


In a sign of what’s to come for your favorite board game, Harmonix announced it’s fixed a “gnarly” Rock Band 4 bug, and next month will deliver a patch that ends a number of scoring exploits. The bad news for players? That also means the games leaderboards will be entirely reset. While players will still have their high scores saved locally, they’ll need to go again for online bragging rights. Speaking of online, in a recent blog post Harmonix said that bringing internet multiplayer to the new game is “very much on the table,” but it hasn’t committed to a timetable.

For the holidays, owners of the new game can finally import tracks from Rock Band 3 (for $15, provided you owned it before as detected by Harmonix’s automated system), and the ability to import tracks from 1, 2 and Lego Rock Band is on deck for January. The last update reworked calibration, added a new Brutal Mode that tests Expert players by tossing new challenges at them depending on how well they’re playing, and there’s an Activity Feed that lets rivals keep an eye on each other more easily.

Is that enough to make Rock Band 4 more than just a game for people to keep in their closet until company comes over? I’m not sure, but it certainly gives some incentives to play on a regular basis, and no matter how frequently one rocks out, I’m looking forward to fixes for a number of the issues and missing features the game launched with. In a Reddit AMA the team said this is the Rock Band game for this generation of game systems, and it seems to be moving more towards the game-as-a-service model with continuous rolling upgrades and expansions. Who knows, if they add enough features (old and new), maybe gamers will be leaving positive Amazon reviews too.

Who makes the best SoC: Intel vs Qualcomm vs Samsung


At the heart of every smartphone and tablet there is a processor known as a System-on-a-Chip (SoC). It contains the CPU, the GPU and various other bits and pieces including a memory controller, cache memory, a DSP and a cellular modem. Not all SoCs are equal, the CPUs differ significantly, as do the GPUs. Some include more auxiliary parts, including various co-processors, while others are more “minimal.”

Don’t miss:

There are lots of Android SoC manufacturers in the world, however in terms of market share Qualcomm and Samsung are the kings. The world’s largest chip maker is of course Intel, however it hasn’t had much success in the mobile space. The main reason is that the dominant system architecture for mobile is ARM. Companies like Qualcomm and Samsung make SoCs based on the ARM architecture, an architecture that is designed primarily for low energy consumption. In fact, every CPU core or GPU system made by ARM is designed to fit within a very tight “thermal budget.” The ARM architecture isn’t just limited to Android, it is also the system architecture at the heart of the iPhone, as well as other mobile handsets like Microsoft’s range of Windows Phones and handsets from Blackberry.

So from Android to iOS, from Windows Phone to Blackberry OS, ARM is the leading system architecture. Things are different when it comes to desktop PCs and laptops. In these sectors the Intel x86 (and x86-64) architecture is the de facto standard and Intel is the leading chip maker. Intel has been trying for several years to cross the divide from desktops to smartphones and it has notched up the occasional win along the way, for example the ASUS Zenfone 2 uses an Intel chip and not one based on ARM.

I recently did a comparison of the leading SoCs from Qualcomm, Samsung, MediaTek and Huawei, all ARM based chips, but in that lineup I didn’t include Intel. It seems that there is some interest to see how Intel compares with the likes of Qualcomm and Samsung, so here is my comparison of the Qualcomm Snapdragon 810, the Samsung Exynos 7420 and the Intel Atom Z3580.

Core Count

cores-on-a-cpuThe two ARM based SoCs in our lineup are octa-core processors using a technology from ARM called big.LITTLE. The idea behind big.LITTLE is that not all the cores are equal. You generally find a cluster of Cortex-A57 cores and a cluster of Cortex-A53 cores. The A57 is a high performance core, while the A53 has greater energy efficiency.

With big.LITTLE that point is less of an issue since the extra four cores are designed to add power efficiency, not higher performance.

When tasks are run on the LITTLE cores they use less power, they drain the battery less, however they may run a little slower. When tasks are run on the big cores, they finish sooner but they use more battery to do so. This is known as Heterogeneous Multi-Processing or HMP.

Intel doesn’t have a HMP solution, instead its philosophy is to use four equal cores with a mix of performance and power efficiency. As a result the Atom Z3580 has a quad core CPU.

Today’s core count is however going to change. The next generation of CPU from Qualcomm, the Snapdragon 820, will go back to using four cores, with a core design cooked up by Qualcomm’s engineers rather than using the core designs from ARM. At the other end, MediaTek will be releasing a SoC with 10 CPU cores, the Helio X20.

GPUs

Another vital part of a SoC is its Graphical Processor or GPU. There are three major designers of mobile GPUs: ARM, Qualcomm and Imagination. ARM’s range of GPUs are known as Mali and includes the Mali-T760, as found in the Exynos 7420. Qualcomm’s GPUs are branded under the Adreno name with the Snapdragon 810 using an Adreno 430. The third player in the GPU space is Imagination with its PowerVR range. Imagination has had the most success on mobile with Apple, as every iPhone since the 3GS has used a PowerVR GPU. However, Imagination has also had some success with Intel as the Atom Z3580 uses the PowerVR G6430.

It is difficult to make a comparison between these GPUs just from the specifications. They all support OpenGL ES 3.1, they all support RenderScript, and they all boast high gigaFLOP numbers. The real test comes when running actual 3D games.

Atom Z3580

Intel_Atom_inside-1280pxThere aren’t that many smartphones which use Intel processors, however one smartphone that made a splash this year was the Asus Zenfone 2. At its core is the Intel Atom Z3580. Built using a 22nm fabrication process, the Z3580 has four cores and includes Imagination’s PowerVR G6430 GPU. It is based on Intel’s Silvermont microarchitecture, which was announced by Intel in on May 6, 2013.  Silvermont was the basis of four different SoC families of which Merrifield and Moorefield were aimed at smartphones.

The microarchitecture was announced in 2013, the Arom Z3580 was launched during Q2 2014 and the Asus Zenfone 2 was released during March 2015. This shows how slow the microprocessor industry can be, however it also shows how Intel prioritizes its products as many Silvermont processors, for other sectors like the desktop, were released in 2013.

Snapdragon 810

snapdragon-810-webpage

The Snapdragon 810 is Qualcomm’s current flagship 64-bit processor. It has eight cores in total, four Cortex-A57 cores and four Cortex-A53 cores. As I mentioned above, this is a HMP SoC using ARM’s big.LITTLE technology. The more power efficient Cortex-A53 cores are used for easier tasks and the Cortex-A57 cores are activated when some heavy lifting is required. Bundled with the CPU is the Adreno 430 GPU, the Hexagon V56 DSP, and an integrated X10 LTE modem.

The history of the Snapdragon 810 has been rocky at best. Samsung didn’t pick it for the Galaxy S6 range, nor for the Note 5, instead opting for its home-grown Exynos 7420. The chip has also been dogged with stories of overheating and CPU throttling. Qualcomm tried to fix the chip’s perceived image by releasing a new stepping known as V2.1, however, with the 4K video overheating issues of phones like the Sony Xperia Z5 Compact, the Snapdragon 810 is still seen negatively by some consumers.

Having said that, my testing of the Snapdragon 810 has shown it to be a fast and reliable SoC for the most part, and it has been picked-up by several top smartphone makers including Huawei for the Nexus 6P, OnePlus for the OnePlus 2, and Motorola for the Moto X Force.

Exynos 7420

Exynos 7 Octa

This is one of the most popular smartphone processors at the moment, mainly because it is the processor used by Samsung for its current range of high-end devices including the Samsung Galaxy S6, the Samsung Galaxy S6 Edge +, and the Samsung Galaxy Note 5. Like the Snapdragon 810 it uses four Cortex-A53 cores and four Cortex-A57 cores. But rather than the Adreno 430, we find an ARM Mali-T760 MP8.

The Mali-T760 has 8 shader cores while boasting a 400% increase in energy efficiency over the ARM Mali-T604. One of the tricks in the Mali-T760’s architecture is the use of bandwidth reduction techniques, which minimizes the amount of data shifted around and hence reduces the amount of power used by the GPU. Such techniques include ARM Frame Buffer Compression (AFBC), which compresses the data as it is passed from one part of the SoC to another; and Smart Composition, which only renders the parts of the frame which have changed.

Thanks to the smaller 14nm FinFET manufacturing process, Samsung has been able to up its clock speeds by 200MHz on the CPU side and by 72MHz on the GPU side, when compared to the Exynos 5433. It is also Samsung’s first SoC with LPDDR4 memory support, which runs in a 32-bit dual-channel configuration with a clock speed of 1552MHz. Peak bandwidth reaches 25.6 GB/s.

The Phones

Intel-vs-Qualcomm-vs-Samsung-SoCs-the-phones

For these tests, I got hold of different phones using these three SoCs. The phones are:

One thing to note is that the Zenfone 2 has several different performance modes. When I first ran a benchmark I got a notification tell me that I should switch to “Performance mode” for the best results, which I did. Consequently all the benchmarks are run with the phone at its highest performance settings. However what is a bit more sinister is that the notification came when the app was started, but before any tests were run. This means that the phone didn’t detect the benchmark because the OS saw high levels of CPU usage, but rather because it recognized the app that was running, in other words it has a built-in database of benchmarks and high performance games that need lots of CPU power. If Asus only goes as far as to send a notification then that is not so bad, but who knows what skulduggery is going on in the back ground once the system knows a benchmark is running!

It is also worth noting that the screen resolution plays a big factor for benchmarks that include GPU tests. Pushing around those pixels on a phone with a Full HD display is less taxing for the CPU and GPU than on a phone with a 2K display.

Performance tests

Getting performance tests right is hard for several reasons. First, replicating the exact same conditions for each test run is difficult as even variations in temperature can alter test results. Second, benchmarks tend to be artificial and don’t reflect real world usages. Therefore when testing it is good to use benchmarks like AnTuTu and Geekbench. But it is also important to simulate real world scenarios like launching a game while monitoring the performance. To further augment these tests I have written a couple of apps. The first one tests the SoCs processing power by calculating a large number of SHA1 hashes, performing a large bubble sort, shuffling a large table and then calculating the first 10 million primes. The second app uses a 2D physics engine to simulate water being poured into a container and measuring the number of droplets that can be processed in 90 seconds. At 60 frames per second the maximum score is 5400.

AnTuTu

Although AnTuTu is one of the “standard” benchmarks for Android that tests both CPU performance and GPU performance, it is important to understand that the test loads used are completely artificial and don’t reflect real life scenarios. However, as long as we take that into consideration then the numbers can be useful to get a general “feel” of how the SoC performs.

I performed two tests with AnTuTu. First, I just ran the test on the device from a fresh boot, then I ran the 3D demo game Epic Citadel for 30 minutes (in the hope of heating up the phones a bit) and then I re-ran the benchmark. The results are below:

Intel-vs-Qualcomm-vs-Samsung-SoCs-AnTuTu

As you can see the Samsung Exynos 7420 is the fastest followed by the Snapdragon 810. Those two results were expected as they come from my comparison of the Snapdragon 810, the Exynos 7420, the MediaTek Helio X10, and the Kirin 935. However the question remained, where would the Intel Atom Z3580 fit? Well as you can see it came in last with a score of under 50,000 while the other two managed over 60,000 peaking near 70,000. Compared to other leading SoCs, only the MediaTek Helio X10 and the Snapdragon 801 perform worse on AnTuTu.

As I said, AnTuTu is an artificial benchmark (as is Geekbench etc), however it does give us a good feel of how the SoC performs. In fact throughout all of the other tests we will see the same story, first Samsung, then Qualcomm and then Intel.

Geekbench

I also performed two tests with Geekbench. First I just ran the test with the device cool, then I ran the 3D demo game Epic Citadel for 30 minutes for the AnTuTu test (see above). Straight after re-running AnTuTu, I then re-ran Geekbench. Here are the results, one graph for the single-core tests and one for the multi-core:

Intel-vs-Qualcomm-vs-Samsung-SoCs-Geekbench-singlecore

The single-core tests show the speed of an individual core, regardless of how many cores there are on the SoC. Here we can see that the individual core performance of the Atom Z3580 is quite poor. It seems to be on-par with a Cortex-A53 or with the 32-bit core of the Qualcomm Snapdragon 801. However one point in the Atom’s favor is that the results are basically unchanged when the device is running hot.

Intel-vs-Qualcomm-vs-Samsung-SoCs-Geekbench-multicore

Since the multi-core test uses all the cores simultaneously, then the Atom Z3580 will under-perform in this scenario as it only has four cores, compared to the eight cores of the other two. There is a lot of debate about how many cores are optimum for performance and power, however with big.LITTLE that point is less of an issue since the extra four cores are designed to add power efficiency, not higher performance.

Interestingly we can see that the Atom actually performs better under this test when warmer! I mentioned previously that the Zenfone 2 had several different performance modes. I set the phone back to its “normal” mode and re-ran Geekbench to see what the difference in performance would be, the result was quite surprising:

Intel-vs-Qualcomm-vs-Samsung-SoCs-Geekbench3-Zenfone2-perf-modes

Clearly the performance mode tweaks the SoC to run faster, however that will also drain the battery faster.

CPU Prime Benchmark

As with the previous two benchmarks, I ran CPU Prime Benchmark twice. The first run was performed when the device was cool and had no other apps running. Then I set each phone to record Full HD video (not 4K) for 10 minutes. After that I re-ran the benchmark. The results are surprising:

Intel-vs-Qualcomm-vs-Samsung-SoCs-cpu-prime-benchmark

In first place again we find the Exynos 7420, followed by the Snapdragon 810 and then the Atom Z3580. Both the Snapdragon 810 and the Intel chip run slower after 10 minutes of video recording, however the Samsung SoC maintains its performance level.

Real world

For something approaching real world usage I picked two tests. The first is how long does it take to startup the Need For Speed No Limits game, and secondly how well do the phones handle the Kraken Javascript benchmark. Kraken was created by Mozilla and measures the speed of several different test cases extracted from real-world applications and libraries. In each case, I used the same version of Chrome downloaded from the Play Store. But first, the Need for Speed startup times:

Intel-vs-Qualcomm-vs-Samsung-SoCs-needforspeed

The caveat is of course that starting a game is not just about the CPU, also the speed of the internal storage plays a major role.

As for Kraken:

Intel-vs-Qualcomm-vs-Samsung-SoCs-kraken

Again, the Kralen tests confirms the relative performance of these three SoCs.

Hashes, bubble sorts, tables and primes

This is the first of my custom benchmarks that tests the CPU without using the GPU. It is a four stage process that first calculates 100 SHA1 hashes on 4K of data, then it performs a large bubble sort on an array of 9000 items. Thirdly, it shuffles a large table one million times, and lastly it calculates the first 10 million primes. The total time needed to do all those things is displayed at the end of the test run. The results are below:

Intel-vs-Qualcomm-vs-Samsung-SoCs-Hashes_bubble_sorts_tables_and_primes

This is the one test that the Exynos 7420 didn’t win, it was beaten by the Qualcomm Snapdragon 810. However the real surprise was the lackluster performance of the Intel Atom SoC… Benchmarks are one thing, but this is how fast Javascript runs in your browser and browsing is one of the main activities we all do on our phones.

Water simulation

The other custom benchmark uses a 2D physics engine to simulate water being poured into a container. The idea here is that while the GPU will be used slightly for the 2D graphics, most of the work will be done by the CPU. The complexity of so many droplets of water will exercise the CPU. One drop of water is added every frame and the app is designed to run at 60 frames per second. The benchmark measures how many droplets are actually processed and how many are missed. The maximum score is 5400, a number which the Exynos 7420 almost hits, but not quite. The full results follow:

Intel-vs-Qualcomm-vs-Samsung-SoCs-water-sim

So the Exynos 7420 almost manages the maximum, with a result just 41 short of the theoretical best. This is doubly impressive when you consider the screen resolution of the Note 5. The Snapdragon 810 comes in second having dropped some 178 frames, but disappointingly the Intel Atom comes in a very poor last place having dropped almost 400 frames.

Battery life

Performance is one SoC characteristic, however its power efficiency is another. There is a rough rule of thumb, you can always increase the performance by using more power. This is especially true in mobile, however using more energy depletes the battery and nobody wants a battery life measured in minutes.

To test the battery life of the three phones I performed two tests. First I ran Epic Citadel on each device for 30 minutes and measured the drop in battery level. With that number I extrapolated the theoretical number of minutes you could run Epic Citadel on a full charge. For the second test I used a small app which I wrote that brings up a series of web pages with a small pause between each page and so mimicking browsing the web. This was run for an hour and the web surfing time extrapolated from the battery level change. Here are the results:

Intel-vs-Qualcomm-vs-Samsung-SoCs-battery-tests

The Z5 Compact and the Note 5 perform roughly the same, both are capable of playing 3D games for 5 hours or surfing the web for 10 hours. The Zenfone fairs slightly worse managing just over 4 hours of 3D gaming or 7.5 hours of browsing.

Understanding these numbers is a little complicated. First of all, each phone has a different screen size and screen resolution. Pushing around more pixels takes more battery power and bigger screens draw more current. Secondly, each phone has a different battery size. The Note 5 has a 3000 mAh battery, as does the Zenfone 2. The Z5 Compact has a smaller battery than the other two, at 2700 mAh.

Dividing the battery size by the browsing time gives us a ratio of mAh per minute of web surfing:

Intel-vs-Qualcomm-vs-Samsung-SoCs-battery-ratios

The Z5 Compact has the smallest screen (4.6 inches) and it also has the lowest resolution (720p). Combined with the big.LITTLE Snapdragon 810 then it offers the best battery life. Next is the Note 5 which has a huge 5.7 inch screen with a massive 1440 x 2560 resolution. However even with such a large high resolution screen it manages a battery surfing ratio of 5. The Zenfone 2 has the worst ratio. The Zenfone 2 has a 5.5 inch, Full HD display and the same battery capacity as the Note 5, yet its battery surfing ratio is 6.51. How much of that is due to the Intel Atom processor?

Wrap-up

Intel’s biggest problem is that it is trying to use the same microarchitecture that it uses on the desktop and squeeze it into a mobile SoC. Creating high performance, power efficient processors is a complex business and ARM has specialized in this field. Every ARM processor is designed specifically for power efficiency while delivering the maximum performance. Intel’s focus is the desktop and servers, places where big ventilation fans are the norm and power usage isn’t as critical as on mobile. Until Intel starts to take mobile seriously it will always come in second, just as demonstrated by the Atom Z3580.

EPFL’s printing technique hides one image behind the other


Remember those holographic cards that give off different colors when you tilt them a certain way? Well, in the video below the fold, the École Polytechnique Fédérale de Lausanne demos metallic cards similar to those, except they’re much, much cooler. The institute has developed a printing technique that prints two images together, and to see the second picture, you merely need to rotate the photo. One card in the video, for instance, looked like it was the image of a gray umbrella, but when rotated 90 degrees, it showed a rainbow-colored one instead.

Here’s how this trick works:

Printers spray ink as tiny dots into precise patterns, a standard technique called halftoning. Different patterns of cyan, magenta and yellow dots produce a wide range of colours.

When the halftone is printed along lines onto metallic sheets, the researchers noticed that the resulting colour depends on the viewing angle. This is because incoming light traversing the ink lines cast shadows onto the metallic surface. Ink lines perpendicular to the incoming light create a large shadow and appear as “strong colors.” Ink lines parallel to the incoming light do not induce a shadow and appear as “weak colors.” When the print is rotated by 90 degrees, strong colors become weak and weak colors become strong.

At the moment, the technique only works if you use an inkjet printer and print on a metallic sheet. But the researchers believe it has a lot of other potential and more useful applications, particularly in the realm of security. The EPFL says it could eventually be used to print security elements for passports, ID cards or paper bills that counterfeiters will have a tough time replicating.

Google is gifting The Beatles to Android users this Holiday season


Just in time for Christmas, The Beatles is set to stream on Google Play and a number of other streaming services, including Slacker, Microsoft Groove etc. A Google blog post says that 13 of Beatles’ original albums, plus four essential Beatles collections, will be available to stream on Google Play Music from December 24.

Earlier, The Beatles’ music was not available in digital format for Android users as Apple had exclusive rights to sell it. Now that the best-selling band is available for Android users, Google seems completely taken over by “Beatlemania” and dedicated an easter egg to it. If you ask your Android phone, “Ok Google, play the Beatles,” it will promptly reply: Let it stream.

Let’s take a look at some of the top searched Beatles albums, according to Google Trends.
