OpenCL Displacement Benchmark - ATI + Nvidia... OpenCL is one of the major new function included in Snow Leopard. A GPU which can use OpenCL - ATI 48xx, NV8xxx/9xxx(M) - can use it to compute C++ like code on it. The code is compiled at runtime of the OpenCL Application so it is (in theory! ;) ) Universal and not vendor specific like CUDA(NV) or ATI Steam
The faster the GPU and slower the CPU the more benefit you are getting when using an OpenCL Application. An Highend MacPro 2009 with lowend GPU isnt really useful for OpenCL, because their great new CPUs reach near lowend GPU OpenCL speed.
But on an Core2Duo even an ATI 4850 or 8800GS GPU may give an useful benefit by using OpenCL.
An GT120 used in an MacPro 2009 is much undersized for OpenCL performance !
GeForce GTX285 Mac is Up to 4 times faster in the same CPU environment.
This Bench should also work on ATI gpus (48xx) - most other OpenCL Apple Demos(Benches) didnt work with 10.6.0 - will be fixed by ATI with 10.6.1 update
