The latest rumors point to a new Nvidia cryptocurrency mining processor capable of an Ethereum mining hash rate of 164MH / s. If you’re unfamiliar with cryptocurrency mining hash rates, this makes it an absolute number of cards: the GeForce RTX 3090 is at 120-130MH / s. Wild, right?
It’s called 170HX, says Twitter’s 9550Pro leaker, and will feature 4,480 CUDA cores and run at 250W. Its secret, how to get a more resistant card to the 350 W RTX 3090, is the choice of memory. There is only 8 GB on the reported card, but that 8 GB is made up of HBM2e, HBM, which literally means High Bandwidth Memory.
Ethereum loves design memory bandwidth. GPUs usually have a lot of them, but even the latest graphics cards for games with GDDR6X VRAM fall into the bandwidth of supply with professional accelerators based on HBM memory. There have been a few memory cards with HBM2, AMD's Vega and Radeon VII memory, but they fell at that time. Interestingly, they have since found a second life in mining.
HBM2e is specifically the widest bandwidth design to date, with each chip offering a bandwidth of up to 410 GB / s. GDDR6X, while similarly bandwidth-wide, handles 84 GB / s.
This CMP chip is likely to use a GPU (GA100) once it hits the market once it is destined for this HBM2e memory accelerator, Nvidia's A100.
The kernel count drops considerably between the A100 and 170HX, from 6,912 to 4,480, but this card also uses HBM2e memory and adapts to a TDP of 250W. That makes him a suspect, at least.
It is also possible that Nvidia is preparing two CMP cards from the GA100 chip envelopes. Earlier rumors suggested a CM100 HX card based on the A100, which could have been an early sign of the 170HX, but was later suggested to be the 220HX with an even more attractive hash rate of 210MH / s.
There’s a reason why gamers may worry about the possibility of such a powerful CMP GPU, and it’s strangely based on the fact that this GPP CMP is really great for mining. Yes, in many ways, a more powerful GPU for mining will mean more money in the miners' pockets, but it can also make less powerful GPUs, such as GeForce and Radeon gaming cards, less desirable for the same. tasca.

In fact, it is something that happened to Bitcoin many years ago with ASICs or application-specific integrated circuits. Bitcoin, unlike Ethereum, works very well with a specific chip built exclusively to deal with the complex calculations needed to extract bitcoins. Individual ASICs could be cheaper and less power consuming, and because of this use of the GPU in Bitcoin mining, it quickly gave way to ASICs. These ASICs are possible with hash rates of more than 100TH / s that eliminate the Bitcoin algorithm.
A single GPU simply has no chance of competing and as the difficulty rate for Bitcoin increases, an indicator of how difficult it is to get a block that is often kept at a steady pace, miners with GPUs should also buy until more powerful ASICs or quit the game.
Ethereum hasn’t happened that much, though there are promising ASICs: GPUs are still great for work because of their great bandwidth by modern standards. A super powerful Nvidia processor for this task, such as one with HBM, could change that.
But it really depends Yes there is this card, how much does Nvidia charge you if it does (the A100 costs about $ 10,000) and how many GPUs you could make / already have around to fit.
This would be a way for Nvidia to replace slightly broken A100 GPUs that are not suitable for professional data center work, in the same way that it says the existing CMP line is not suitable for gaming. Existing training exceeds 86MH / s with 90HX, although it is slated for launch in Q2, so it may not be out yet.
One thing seems clear, though: Nvidia has a lot to gain from this card, in addition to the success of the wider CMP range. According to the leaked table, the 170HX could also arrive this quarter, in Nvidia’s business calendar, which is weird, anytime in June-August.
