Older iMac graphics card compatibility with CC 2023

It will be painfully slow. Older AMD GPUs simply do not work well at all with Premiere Pro; in fact, the 570X is not sufficiently faster than integrated on-CPU graphics to justify the added expense of one.

Worse, Adobe video editing apps such as Premiere and After Effects will choke badly on any GPU that hss less than 8 GB of VRAM (especially when called to render high-frame rate 4k or any 6k or higher video) because they are, relatively speaking, VRAM-intensive. And what will happen there is that the GPU acceleration will cut out completely in the middle of a rendering job due to the depletion of graphics RAM and force all rendering to the software-only (or CPU-only) mode for the remainder of the rendering.

for sone apps it will be ok (eg, acrobat). for some (eg, premiere). it won't.

It is on the list of recommended cards for Premiere Pro:

EDIT: I guess that doesn't necesssarily mean it's OK for premiere Pro.

I stand corrected. @kglad  @RjL190365 

I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the Video Hardware forum so that proper help can be offered.
