rev120 lowers SSE2-performance when Stream-core is installed about pyrit HOT 4 CLOSED

I've a ATI 4850 now and will look into this next week..

I can't confirm the problem on my box. Is it still present with r130 ?

Gave this a test on my laptop with r130 and got as below

Pretty bad ati card, its a radeon 3650 HD mobility and think its an intel T9400
running on ubuntu 9.04 64bit. On r120 the results were worse than r130, with it
running about 500PMKs/s

The ATI-Core sucks away some of the CPU-time - that's why you get only 600 
PMKs/s
instead of 700 PMKs/s from the CPU while the ATI-Core is active. Usually the 
GPU is
multiple times faster than the CPU so the burden put upon the CPU is no 
problem. 


I consider this closed for now, please report back if you have further problems
