AMD

I wouldnt say so. 5800X3D. 99% constant GPU use.

I'm talking about the performance progression in terms of raw power (the board can get up to 225W and in many games uses only 180 or 190 due to driver adjustment on some tittles) and driver improvement.

Performance is good. I'm pointing at the lesser improvement or effort when we compaire to Rx 400/500 series of Polaris. I think as they were weaker they've made a bigger effort. Now that they're "fine" with the last RDNA1 and RDNA2 architectures...substantial fps gains are only throughout software techniques. That's my point.
