About sandra... On my machine it's the same. Double precision is too low. In OpenCL is the same. But in Stream test, results are normal. It's just another "mystery" of ATI's drivers...
Does someone know if SmallLuxGPU can use the two chips in 5970? I think there is some problem, and the program is compiled only on the first device. The second one gives black.
Thanks, Dade, I understand that. I was wondering how Fermi's cache will help in real world scenario like in case of SmallLuxGPU. Will wait to see the updated results of Cho.
