effect of memory speed on completion times? - Page 2

post #11 of 19
Perhaps AMD POEM performance is linked more directly with PCIe speeds than Nvidia cards?

Just a guess but It's probably more of a driver issue. POEM uses OpenCl for the GPU and AMD driver support for OpenCL is far superior than Nvidias.

As DarkRyder said, experiment with ALL settings to get best performance/Watt... and know that all GPU projects differ greatly. Einstein uses a LOT of PCIe bandwidth and needs a 16 lane slot for max speed using for instance a GTX580. Using a 9800GT card would be a different story. Einstein on AMD I don't know.

Sooo, depending on the project, all facets of the setup come into play and are as individual to each system as they are to GPU's...

What's sad is bitcoin and crypt currency mining has such a large backing to calculate and analyze these things but actual research like POEM@Home, Rosetta@Home,etc. do not.

like a tach. would be cool to have a windows gadget on desktop to estimate current gflops/tflops speed.

will have to look into that.
