Hmm. I’ve decided I don’t like you.

It feels like you’re setting an artificially high goal purely to make challenging your assirtion impossible. I’m not even sure a 3090 can do path tracing. 40/5090, maybe they can.

Could an AMD card do it? Yes. RX 7900 possibly, a theoretical RX 9090 could if they bothered to release one.

But none of that matters really. Never has.

A RX 6800? Yes, in fact I was playing CP2077 with FSR and ray tracing on at 4K on a 6800. It was the first real card AMD had that could. Though it did struggle at times.

Sadly replaced after 4 years with a RX9060 of similar capability but better Ray tracing.

AMD cards are only about 2-3 years behind NVIDIA in a lot of specialised tasks, but trying to pace the behemoth that is NVIDIA’s RnD with a much smaller budget. ROCm works but is held up by compatibility issues with the newer CUDA features.
