how many CUDA cores does physx use? Worth using a redundant 9800GT along with my GTX780 SLI? - Page 2

post #11 of 12
Thread Starter 
removed the 9800GT - I ran some tests and it had a negative difference.

I go off this wiki for comparisons of GPUs... http://en.wikipedia.org/wiki/Comparison_of_Nvidia_graphics_processing_units

according to that page the 9800GT can perform 504 GFLOP/s with its 112 CUDA cores, the GTS 450 achieves between 455 - 601 GFLOP/s depending on its variant. However, those figures are calculated theoretically as the definition of a FLOP is simply a FLoating-point OPeration and derived from clock speed etc so doesn't account for differences in architecture.

I'll bow to your experience as I don't have a 450.

Anyway it's no longer in my system

no problem. I think that the amount of gpu horsepower that is available to us today, is more than sufficient enough to pull tech from like 6+ years ago. Dedicated PhysX gpu was a necessary thing before, and it still is, but only when running ATI/AMD as main. 780 has so much power, that calculating PhysX for it is like putting Terminator against Wall-E tongue.gif
