I own an old Mac Pro 5,1 that I’d love to upgrade with a new CPU & GPU to also be able to use one of the latest macOS.
Due to the basically inexistent NVIDIA support in newer macOSs, I think about getting an AMD GPU - the RX480 or RX580. Currently I still use an NVIDIA GPU + CUDA and have no experience with OpenCl.
Is there a major difference when it comes to performance?
And could someone who owns and uses a RX480/580 maybe share her/his experience with its performance in Blender 2.8 - 2.9? Are you satisfied with the card & performance?
I also have Windows and Linux on my Mac and could theoratically still use a NVIDIA card, this would just mean I have to stick with my old macOS and use Windows/Linux for blender.
Considering all that, would you still consider the switch to AMD as a good plan or should I rather stick to NVIDIA?
