I hear a lot of varying conversation about GPUs in the Hackintosh community. I have heard repeatedly that Apple codes FCP (iMovie & Photos too?) to work best with AMD graphics (QuickSync?). Hence why I see render times on older machines that rival builds I've found with a 7700k and NVIDIA cards. But, there are many Apple machines that have NVIDIA graphics. And did I hear correctly that the NVIDIA 10series of cards will be in the next MacPro?
So what gives? What is the more precise answer? Thanks!
My understanding is that FCPX works better with AMD video cards. Period. That's not to say you won't get acceleration from Nvidia cards in FCPX, but it's just better with an AMD card.
I have not heard of any significant differences in iMovie or Photos using AMD or Nvidia.
If the app you use is heavily dependent on GPU, find out which GPUs work best with the apps you use.
While AMD holds the advantage for FCPX usage, Nvidia holds the advantage with other apps, specifically apps that make use of Cuda and Adobe apps. This plus the fact that, currently, Nvidia cards generally work a little better in hackintoshes, is probably why you see lots of hackintoshes using Nvidia.
I have not read of or seen any indication that 10-series Nvidia cards will be included with the next Mac Pro.
