I have a MacBook Pro, which I specifically bought earlier this year to get CUDA GPU enhancement with CS6.
In the latest version of Premiere Pro, I now have an option for OpenCL as well as CUDA (before OpenGL was not available). In fact, now all new projects default to OpenCL, and it is changing my old projects that were set to CUDA to OpenGL.
I have tried flopping back and forth, I haven’t noticed a big difference in performance. I have some RED 4K sequences with some 5D 1080/720 shots mixed in, and MAYBE those play back a bit better in CUDA over OpenCL?
My instinct is that because the MacBookPro has NVidia cards, and that CUDA is a brand-specific NVidia platform, that CUDA should work better for my setup? And that OpenCL would be better suited to non-NVidia cards?
But I have also read that OpenCL is faster than CUDA?
And the fact that CC 7.2 is changing all my old projects from CUDA to OpenCL, and is defaulting to OpenCL, suggests that Adobe REALLY wants me to use OpenCL now.
Right now Open CL is definitely not faster than CUDA in any application that has both. I am not sure where you read that but that is absolutely incorrect. I would suggest you set it to CUDA if you want better performance. Nvidia GPU’s also do not work as well with Open CL as they do CUDA BTW.
