GPU required for MacPro6,1 running OSX 10.11

[John Rofrano]

I don’t believe there is a commercial solution to your problem for 2 reasons:

1. Thunderbolt 2 is not fast enough to support a modern external GPU card. Thunderbolt 2 is about as fast as a PCIe 8x slot and modern GPU’s require a PCIe 16 slot bandwidth. You need Thunderbolt 3 which the MacPro6,1 doesn’t have.
2. No external PCIe enclosures have a big enough power supply to support today’s power hungry GPU card.

This is why currently no Thunderbolt 2 PCIe Expansion Chassis list any Graphics cards a being supported and some even say that it will not support a GPU.

What about AKITIO announcement of Thunderbolt 3 (Type-C) …?

Plus a real question: AMD FirePro D700 works on Open CL architecture…and Nvidia works on Open GL…The question is which is the best External GPU support for NEW MACPRO 2016 that will feed the GPU Hungry applications like resolve and scratch… ??

[Ehtesham Khan Ham] “AMD FirePro D700 works on Open CL architecture…and Nvidia works on Open GL…”

Actually that’s not quite correct. Open GL is an API for rendering 2D and 3D vector graphics. It has nothing to do with processing video (other than vector graphics titles and such) and works equality well on AMD and NVIDIA GPU’s as does Open CL which is a general purpose computation API for parallel processing.

Danvinci Resolve requires Open CL which the Mac Pro’s dual FirePro D700s already support. I’m not sure why there’s a question here.
