Leak shows Inno3D cryptocurrency mining card based on the GTX 1080 Ti

by John_A

Recent rumors suggest Nvidia will soon release dedicated cryptocurrency cards codenamed “Turing.” The cards would presumably be based on a modified version of the company’s latest graphics chip architecture Volta. But a new leak suggests that the upcoming cryptocurrency mining cards may use a version of the  older “Pascal” chips installed in the company’s GTX 1080 TI and Titan-branded cards. 

The leak stems from an upcoming Inno3D card packing the P102-100 graphics chip, but no bracket for attaching it to a mining frame, or video output. It also appears to use Inno3D’s Twin X2 cooler design sporting two fans and five heatpipes. Here are the specifications compared to the GTX 1080 Ti card: 


Inno3D card 

GeForce GTX 1080 Ti 

Graphics chip: 



CUDA cores: 



Base speed: 



Boost speed: 






Memory clock: 



Memory interface width: 



Memory bandwidth: 



Power use: 

250 watts

Power connection: 

2x 8-pin 

1x 6-pin, 1x 8-pin 

Bus support: 

PCI Express Gen1 x4 

PCI Express Gen3 x16 


Dual slot
8.46 (L) x 4.92 (H) inches 

Dual slot
10.5 (L) x 4.376 (H) inches 

 As the specifications show, Inno3D’s model for miners is a cutdown version of the GeForce GTX 1080 Ti graphics card for PC gamers. It has a lower core count, lower amount of on-board memory, a smaller interface width, and a smaller memory bandwidth. Additionally, the specifications show the card may simply run at 1,582MHz rather than fluctuate between two speeds as seen with the GTX 1080 Ti. 

Now here are the hash rates supposedly proposed by Inno3D: 


~47 MH/s 


~660 Sol/s 


~879 H/s 

 Nvidia quietly introduced two graphics chips dedicated to cryptocurrency mining last summer: The P106-100 and the P104-100. Cards based on these two chips weren’t released by Nvidia, but rather third-party manufacturers including Asus, Colorful, EVGA, Galaxy, Inno3D, MSI, and Zotac. Both are based on Nvidia’s previous-generation “Pascal” design, and the new leaked Inno3D card could serve as a high-end Pascal-based product that will be cheaper than Nvidia’s rumored “Turing” cards for miners arriving this year.

As a reference, Nvidia provides the GP106 chip in its GTX 1060 graphics cards for PC gamers while the GP104 serves as the source in its GTX 1070, GTX 1070 Ti, and GTX 1080 cards. Meanwhile, the GP102 can be seen in the Titan Xp, Titan X, and GTX 1080 Ti high-end graphics cards. Previous rumors indicated that Nvidia would discontinue its Pascal-based graphics chips, but the Inno3D leak reveals Nvidia still has plans for its previous-generation GPU family. 

Exactly when Nvidia will reveal its new generation of graphics chips is still up in the air. “Volta” is its current GPU design seen in the Nvidia Titan V for desktop gamers costing $2,999 along with the Tesla V100 card for data centers. Following these cards will be the GeForce GTX 20 Series for gamers dubbed as “Ampere,” and cryptocurrency mining cards dubbed as “Turing.” But given the new Inno3D leak, whether Turing will depend on Pascal or Volta remains to be seen. 

Editors’ Recommendations

  • New report says Nvidia unlikely to reveal new GeForce cards in March
  • Digital coin miners purchased more than 3 million graphics cards in 2017
  • The best graphics cards
