The Photoshop CC 14.2 update provides GPU compatibility support for the new Apple Mac Pro. The 14.2 update will allow Photoshop to take full advantage of one of the two available GPUs at a time. We expect to add support for both of the new Apple Mac Pro’s GPUs, and continue to optimize our customers experience by supporting additional GPU operations in a future release. Each of the two GPUs in the base model of Mac Pro are faster than the GPUs available in any other Mac model, and provide plenty of speed and VRAM (memory on the GPU card) for most operations. If you spend a great deal of time editing very large images using one of the GPU-accelerated Photoshop features such as Blur Gallery, Liquify, or 3D, we expect this gain to be significant. (The 6GB VRAM in the highest end GPU option would only be needed for the largest 3D models).
