The CMP series has been talked about a lot, but no one really knows what the GPUs are actually based on, aside from the official information that NVIDIA has posted. VideoCardz has just worked with a close source to confirm the specifications of the silicon on the CMP series cards and it looks like only the top variant will be featuring the Ampere architecture while the rest will be based on the Turing design.

The NVIDIA CMP (Crypto Mining Processor) series of GPUs were announced a few weeks back in a bid to tackle miners from grabbing GeForce gaming GPUs. Four GPU variants were announced with the sub-40 MH/s designs launching this quarter followed by the higher-end designs in Q2 2021. But we never got to know what the exact specifications of these GPUs were until now. In addition to the source, Kopite7kimi also unveiled the exact GPU configurations for the CMP lineup which we have detailed below.
