Is there a way to use CPU and GPU for Blender or 3D Rendering in general? Vega 56 i7

[A.Tony]

Hello,

i currently have the problem, that Blender only renders on my CPU (i7 8700K). ai recently changed my SMBIOS to iMac Pro so that my Mac now supports the GPU, but the Problem now is, that Blender ony uses the GPU now for rendering. Is there a way to use both? Also for all Programs.

My systems is on the Left

Interesting, as soon as I upgraded to Big Sur (SMBIOS iMacPro1,1), Blender stopped showing me the options under System to even select a GPU (beforehand, it said there were no compatible GPUs--I use Radeon VII). Do you know if there is another way to check on Blender what it's using?

EDIT: found it under Add-Ons. It doesn't even recognize my GPU and renders all through CPU. Hmmm. Wonder if that's the lack of support for AMD GPU issue some people talk about.
