In an try to alleviate a few of its Ampere inventory, Nvidia lately launched the Cryptocurrency Mining Processor (CMP) product line that particularly targets Ethereum mining. Whereas the chipmaker was reluctant to share extra particulars, the reality has come to mild within the newest GeForce Sport Prepared 461.72 WHQL driver.
When Nvidia launched CMP, the chipmaker was agency on the truth that it would not affect the availability of its GeForce gaming graphics playing cards. Since CMP was designed to resolve the cryptocurrency mining scenario with Ampere, it might make sense that the graphics playing cards have been primarily based on older silicon. VideoCardz dug into the 461.72 driver and found that the gadget IDs for the 30HX and 40HX are carefully associated to Turing.
There have been little clues that urged that CMP wasn’t primarily based on Ampere from the starty. For one, the CMP models introduced greater energy consumption with a lot decrease hash charges. Moreover, the SKUs, such because the 30HX and 40HX resembled the GeForce GTX 1660 Super and GeForce RTX 2070, respectively, by way of reminiscence capability, energy draw, energy connectors and hash fee efficiency. Subsequently, it’s extremely believable that the 30HX relies on the TU116 silicon, whereas the 40HX is constructed across the TU106 silicon.

Then again, the 50HX and 90HX will not be out there till the second quarter of this yr so these two fashions aren’t in Nvidia’s driver but. Nevertheless, we have now some suspicions that that the 50HX could also be utilizing the TU102 silicon, which is the one which powers the GeForce RTX 2080 Ti. The 50HX seems to be a decrease clocked model of the previous flagship with 1GB much less reminiscence.
The 90HX appears to take after the GeForce RTX 3080. In that case, it might be the one CMP gadget to leverage the Ampere silicon, extra particularly the GA102. Our take is that Nvidia might be recycling faulty GA102 dies that do not meet the specs for the GeForce RTX 3080 or RTX 3090 and sticking them into the 90HX. It is an effective way to maximise yields in any case.
Reutilizing Turing to cushion Ampere’s shortages is a good suggestion on condition that Turing continues to be on TSMC’s older 12nm course of node. Moreover, it’d permit Nvidia to dump leftover Turing silicon. Since Nvidia tapped into Samsung’s 8nm course of node for Ampere, CMP manufacturing has no affect on the brand new GeForce gaming graphics playing cards. However whether or not CMP can persuade cryptocurrency miners to put off Ampere is one other query.
There’s nonetheless loads that we do not learn about Nvidia’s CMP choices although. Since CMP relies on Turing, there needs to be headroom for hash fee optimization. It is going to be fascinating to see whether or not Nvidia will put a lock on CMP’s efficiency prefer it did with the GeForce RTX 3060. Extra importantly, we’ll want to take a look at rhe pricing for CMP as a result of if it is not priced proper, cryptocurrency miners would simply proceed to scavenge GeForce merchandise as a substitute.
