According to Zhihu user, a crytoming card named NVIDIA CMP 170HX now leaked online. Unlike other CMP HX mining cards, the CMP 170HX is designed by NVIDIA itself.
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. It is the first NVIDIA’s own design for a mining card as far as we know.
NVIDIA CMP 170HX has 4480 CUDA cores, which is only 54% of all cores present in the GA100 silicon. For comparison, the GA100 in A100 features 6912 CUDA cores which are 84% of active cores. In terms of memory size, the CMP 170HX has a massive reduction as well. Instead of 40GB or 80GB present in various A100 models, the 170HX only offers 8GB HBM2e memory, supposedly in four stacks (judging from the 4096-bit bus), and a maximum bandwidth of 1.493 GB/s.
In the actual mining test using the Ethash algorithm, the GPU offers up to 164 MH/s without optimizations. Just as much as NVIDIA promised in their official specification datasheet. It is nowhere near 200 MH/s and it might be hard to reach such a hash rate, the author notes.
