It appears that NVIDIA has found a use for its broken GA100 GPUs. The NVIDIA CMP 170HX crypto mining processor has been spotted along with hash rate test results. The passively cooled card has 4,480 CUDA cores, roughly half of what’s found in the A100. It features 8 GB of HBM2e memory on a 4,096-bit bus for a bandwidth of 1.493 GB/s and base/boost clock speeds of 1,140 MHz/1,410 MHz.
The current BIOS does not support overclocking, but the card reached 164 MH/s on the Ethash algorithm. That is lower than the 200 MH/s expected. The card began to throttle at 70°c, further reducing the hash rate. Power draw was 250 watts. The card uses an 8-pin CPU style connector, so the user needed an adapter for it. They were able to reduce the TDP to 190 watts and maintain 158 MH/s. It is two slots wide, and there are no display connectors. The PCIe version is 1.0 x 4.
The CMP 170HX is a repurposed NVIDIA A100 accelerator, which has no display connectors and no gaming functionality. NVIDIA couldn’t figure out what to do with broken GA100 GPUs, which is why they are now offering this highly advanced Ampere GPU out to miners.
