Hello everyone,
If if try to crack password with 9800GT for example, hashcat says:
"Device#1 : GeForce 9800GT, 512MB, 1500Mhz, 14MCU"
what is this 14MCU? I'v noticed that if I multiply that number with 8, I get 112 which is number of cores for this card in Nvidia's specification.
Cheers
MCU is the compute unit, which is a simultaneous multiprocessor. you have 14 of them. on your architecture, each MCU has 8 shaders, which nvidia calls "cuda cores." 8*14 = 112 total shaders.

Can I compare processing on GPU's with processing on CPU's? I mean, can I say that CPU have, for example, 4 cores for hash cracking while GPU in this case has 14 cores for hash cracking, and that's why GPU's are much faster for this type of job?

Ok, one more thing, is this 3200 Stream Processing Units on ATI card same as 112 cores on my card? I mean, they represent same thing?
yes. keep reading further down that page.
