NVIDIA CMP 40HX

8 GB GDDR6 · 256-bit · 2,304 cores

A cryptocurrency mining card from NVIDIA's CMP HX line, announced in February 2021 alongside the hash-rate-limited GeForce RTX 3060 to steer miners away from gaming cards during the GPU shortage. It uses a Turing TU106 GPU with 8 GB of GDDR6, has no display outputs, and was rated by NVIDIA at 36 MH/s for Ethereum at 185 W. Cards were sold through NVIDIA board partners rather than at retail.
