Some of NVIDIA's CMP mining chips will leverage the 12nm Turing architecture: however, specs indicate that CMP 50HX and CMP 90HX could put supply pressure on Ampere gaming cards

Videocardz recently reported that NVIDIA's upcoming CMP crypto mining cards won't use Ampere GPUs, but will leverage older Turing hardware built on the 12nm process. This could come as a boon for those worried that the introduction of CMP would further constrain the supply of NVIDIA's 8nm Ampere GPUs. Thankfully, it appears as though these Turing-based crypto mining cards will not have an impact on Ampere supply.
According to the report, the CMP 30HX, which NVIDIA earlier cited as having an ETH hash rate of 26 MH/s, will be based on TU116, the same GPU powering the GeForce GTX 1660 Super and GeForce GTX 1650 Super. On the hand, the CMP 40HX will be based on the TU106 GPU that powers the GeForce RTX 2060.
NVIDIA announced two further CMP cards, the CMP 50HX and CMP 90HX. However, going by the specs, these seem likely to be Ampere cards. Both the CMP 50HX and CMP 90HX feature 10GB VRAM buffers. And tellingly, the CMP 90HX features a 320W TDP. There are no Turing cards out in the market with 10GB of VRAM, and the GeForce RTX 3080 is the only graphics on the market with a 320W TDP at reference clocks. The 50HX and 90HX are poised for a Q2 2021 launch, however, by which time Ampere GPU supply might actually improve.
