Can i use GPU Acceleration while using External GPU for Mac with Radeon Graphics Card ?

[danokadoni]

Hi everyone,

I have some plan in the future to using my old macbook with an external GPU.

but in apple site, they said only Radeon graphics card that can be used as "Plug and Play" in any mac that supported external GPU.

if i want to use Nvidia (Cuda) i have to bootcamp with windows which i dont want to.

The question is, can adobe After effects and Premiere get advantage in GPU Acceleration if i using Radeon in Mac ?.

Some options like "Metal" can be found in premiere . but im not sure about After Effects. 
is there someone here using the same setup that i want to use ?.

Thankyou..

You'll likely run into a ton of issues with this on an "older Mac" due to their internal GPUs conflicting with this or the first generation Thunderbolt connections working unreliable. that and of course it entirely depends what kind of AE projects you actually do. AE's hardware usage is still limited and you can't expect to spice up an old machine and suddenly AE will be five times as fast. So at the end of the day this could be an experiment that won't pay off and it might be better to just save the money on a completely new machine.
