If you’re editing with Adobe Premiere Pro CS5 or CS5.5 on a MacBook Pro and have been longing for some CUDA “hardware acceleration” it’s time to break out the champagne and buy your CS6 upgrade. Adobe has announced that Premiere Pro CS6 will now support GPU acceleration using OpenCL on MacBook Pros packing certain AMD GPUs.
Quick primer; starting with Premiere Pro CS5, Adobe started using the GPU on certain graphics cards to accelerate processing for many things in Premiere Pro. This helped speed things up and take the burden off the CPU. The GPU processing used Nvidia CUDA technology but sadly that left MacBook Pro users S.O.L since their systems came with built in GPUs from AMD. Now that’s changed. Everything that could be accelerated with CUDA can now be accelerated with OpenCL, except for four effects; Fast Blur, Gaussion Blur, Directional Blur, and Basic 3D.
The system requirements for OpenCL Processing in Premiere Pro CS6 are:
AMD Radeon HD 6750M and AMD Radeon HD 6770M graphics card with 1GB VRAM in MacBook Pro computers running Mac OSX v10.7
So if you haven’t upgraded your system to 10.7, here’s a good reason. Adobe says the Mac OSX v10.7.4 update makes performance with OpenCL significantly better and that it’s important to make sure all of your software is up to date.
While the two AMD GPUs are currently the only ones supported for OpenCL acceleration in Premiere Pro CS6, it sounds like support for more GPUs will likely follow.
