ATI: 4850, 4870 - maybe 10.6.2 update needed to run withput failures
OPENCL - background information:
OpenCL is an API for universal GPU(CPU) computing, Mac OS X 10.6 supports that
Main difference to CUDA / ATI STEAM is: both APIs ate vendor specific.A CUDA (NV) app like badaboom(h264 on GPU) can't work on an ATI gpu and vice versa
OpenCL is universal means:
Xcode compiles an code which includes the source (C like) for the gpu That source is , different to CUDA/ATI STEAM, compiled later by OpenCL at runtime ! So same App can run on complete different gpus and also , without/less code change on CPU if no OPENCL gpu (newer ones) is available. GPU advantadge may vary - from 2 up to 40 faster, depends GPU type and CPU´s typeOpenCL speedup could be even faster, if the memory transfer/access between GPU and CPU would be faster. PCIe Memory Transferlimit outperforms such GPUs like GTX285. I believe in 2011+ some new PCIe Versions will be developed for higher bandwidth over PCIe
What's new in OpenCL Benchmark
Added 3 OpenCl benches/demos from Nvidia (may run on ATI latzer with 10.6.2)
Teapot - very much difference between CPU and GPU
Shows CPU<>GPU bottleneck for memory transfers over PCIe
