You might want to look at this for a good comparison:
Just to give an idea of what the GTX-580 does here are some results. There is no smallPT results as there is a bug in smallpt tests that causes it to report negative values when the values are too large to fit into its integer type according to Micheal.
I should note that the gluxMark is not directly comparable either. Micheal ran them @ 1920x1080 vs my 1920x1200.
Can anyone tell me how to get the OpenCL stuff to run? I've installed the latest Nvidia drivers, 260.19.29, but when I install the phoronix-test-suite packages it says I need to install the Nvidia OpenCL package. I've googled and looked on the forums, but I can't find anything about how to get OpenCL to work.
I have an 8800GT, gtx 460, and a gtx 470 that I'd like to benchmark.
The benches require that the openCL headers be placed in /usr/include/CL/. The headers you can get when you install the cuda sdk available here:
Thanks! I'll give that a shot.
