NVIDIA A100-PCIE-40GB brings only 120kH/s
#1
Hi
i'm wondering why hashcat performance is below other crackers with A100 Cards
i attached the benchmarks and Card Infos as text file
Nvidia Driver and CUDA ist latest version 520

any hints?

hashcat -D 2 -m 11300 -a 3 -o outfile.txt --session crack.session -1 ?l?u 300.hash ?1?l?l?l?l?l?d?d?d

Bitcoin/Litecoin hashes have variable difficulty and thus varying speeds. Your benchmark of ~14kh/s per A100 is pretty much exactly on target for what I would expect. The speeds you are seeing in the above cracking session are significantly higher than the benchmark speed which means the hash used is weaker than the one we use for benchmarking. It likely has a lower round count, which would contribute to the faster speeds.

Thanks for your quick reply

i just compared to benchmarks found on the internet
are there really single cards out there which have mH/s with one single card?
