Linux vs Win speed

[skalderis]

I get better performance in Ubuntu 18.04 vs Win7. In Ubuntu, hashcat chooses different -n -u -T values ant it works faster 8-11% on few tested hashes. I tried forcing these values in Win7 but I get same (low) result. Card is EVGA GTX1080 Classified. Both OS on stock clock. There is difference in driver version (Win7 442.19 / Ubuntu 418.43) and cuda versions (10.2 vs 10.1). Still, in Win7 using latest drivers. Wiki implies no difference in speed between OS's, but in my case I just can't make it work on the same level as in Ubuntu. Can anyone confirm this on any Linux distro?

Forcing same -n -u -T values in Windows as per 1st example top:

Code:

hashcat64.exe -m 16800 -a 3 -n 128 -u 64 -T 1024 d:\test.16800 ?a?a?a?a?a?a?a?a --force

Code:

hashcat --version

[skalderis]

Code:

D:\hashcat-5.1.0>hashcat64.exe --version

v5.1.0

EDIT: in both OS

[philsmd]

did you try to use beta for both systems (https://hashcat.net/beta) ?

what might also make the difference is as you said the driver version, tuning software (performance/power levels, memory speeds) and some other configurations (like x11 config file etc).

I would recommend to test with both system using the beta and explain how you set up the linux system (and if you use some tuning software like afterburner etc)

Tried beta with updated drivers. Results normalized. PMKID +7%. Never occurred to me to try beta.
Thanks for tips!

Hi,
How are things going with speeds on different OS in 2024?
