RandomX is pretty GPU-hostile. If you have a lot of VRAM, you could theoretically make it work okay, but I don't know of a GPU miner that has any semblance of performance (or perf/watt) that is close to a CPU.
Gotcha, CPUs have been most of my experience with it.
I dabbled with GPUs but it seemed like I'd have to do a lot of clock/voltage tuning to make it worthwhile. This was way before energy prices jumping, too
