>There is a reason why AMD finally got competive after they moved away from GCN and created dedicated architecture for compute and gaming
yeah and it bit them in the ass massively, their rocm stack was wayyy behind on rdna for years, and as such they lost prosumer customers, rdna is better at somethings, but it sucked for anything non-gaming, amd has lost marketshare every year since rdna launched.
Amd's last proper GCN gpu was vega 20, it supports everything under the sun computationally, does half rate fp64, double rate fp16, and quad rate int8( which is particularly important for machine learning workloads) , rdna 1 fixes some efficiency problems like bandwidth requirements,increases total occupancy and lowers latency, but it sacrifices int8 and fp64, and there is basically no software support outside of 3d apis, you wanna know why amd had no DLSS competitior until now ? its the lack of int8, why raytracing sucks ass? rdna's compute capabilities are more limited, There was a recent patch for emulated rt on radv , and it literally brings up the rt performance so much, that the radeon VII is faster than entry level rx 6000 series cards in raytracing via brute force alone. Its frankly embarrassing, probably jeet extraordinaire raja to blame for this fuckup, only now with rdna4 have they unfucked themselves.
