Leak shows cryptocurrency mining card with surprising Nvidia chip

Kevin Parrish
By

Recent rumors suggest Nvidia will soon release dedicated cryptocurrency cards codenamed “Turing.” The cards would presumably be based on a modified version of the Volta architecture, Nvidia’s latest graphics chip designs — but a new leak suggests that the upcoming mining cards may use a version of the older Pascal chips from 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:

 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, less 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: 

Ethereum:  ~47 MH/s 
Zcash: 

~660 Sol/s 
Monero: 

~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.

Are Nvidia’s rumored Lite Hash Rate GPUs enough to fix supply woes?
RTX 3080 graphics card on a table.

After a botched effort to limit the appeal of its GeForce RTX 3060 graphics cards with cryptocurrency miners, Nvidia may be back with a new strategy designed to keep its GPUs in the hands of gamers. The company is rumored to be working on a refresh of its existing lineup of GeForce RTX 3000 series GPUs, which are based on the Ampere architecture.

The new solution? A feature known as Lite Hash Rate (LHR), which will limit the hash rate capabilities of the card and make it unattractive for mining currencies like Ethereum. Unlike past efforts, LHR is said to be nearly impossible to bypass. In essence, Nvidia's second software-based stab at limiting the crypto mining appeal of its GPUs is designed to keep more of its graphics cards on the market for gamers, but such a strategy may not result in a more meaningful supply of GPUs for purchase.

Note: This was a rather sly but fun April Fools' joke from Wccftech. Fun to imagine though!

While gamers are still struggling to get their hands on Nvidia's latest GeForce RTX 3000 series graphics cards based on the Ampere architecture, Nvidia is already hard at work on the successor to the flagship RTX 3080. Powering the company's next-gen GPU is a new architecture known as Hopper, and a recent leak reveals that the company's next graphics card refresh will come with a brand-new design that packs in more than 100 billion transistors.

How to mine Bitcoin
Graphics cards in a crypto mining farm.

If you want to know how to mine Bitcoin, you can take two different steps: Go through a cloud mining company, or buy and use purpose-built hardware. We'll look at both options and why, though neither is cheap, cloud mining represents the safest investment for your money.

Remember, research is essential! As for buying Bitcoin or altcoins, you need to be aware that nothing in the world of cryptocurrencies is guaranteed. Any investment could be lost, so make sure you do your reading before pulling out your credit card and have a secure Bitcoin wallet standing by. As with all of our cryptocurrency coverage here on Digital Trends, this should not be considered financial advice.
