What does "MCU" stands for? - djzmaj - 04-07-2013
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?

not exactly. there's a comprehensive explanation for beginners here: https://en.bitcoin.it/wiki/Why_a_GPU_mines_faster_than_a_CPU#A_CPU_is_an_executive

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.
