![]() You can put an nvidia 600 series card in to a mac pro as a secondary card and use it as a CUDA engine for software like resolve. The 5870 might be a bit faster but as you can see none of them are performing as well as similarly priced nvidia cards using CUDA. The 6850 is one of the faster AMD cards recognized by OS X. Obviously this will depend on what you are doing in the software but that should be a good point of reference for performance differences. ![]() ![]() ![]() For instance I get ~30FPS on an nvidia GTX660TI through CUDA, only about 8FPS with an nvidia GT640 and under 4FPS with an AMD 6850 through OpenCL. AMD/ATI cards work with OpenCL, and so far the performance has been limited. It is true that Nvidia CUDA enabled GPUs seem to run fastest in my experience.
