Yea increasing the cache is certainly going to be interesting at higher resolutions with RDNA3. AMD themselves recognizes that once you go above a certain amount of cache, the diminishing return kicks in as well as higher the resolution, the lower the hit rate on the cache itself.
And of course, once you start lowering the cache in an architecture that relies heavily on cache to perform... Then the performance starts to fall off along with it and relies more and more on external memory bandwidth.
For example a guest on @3DCenter_org rightly remarked that the miss rate is more telling when judging the size of the Infinity Cache:https://t.co/gIKWTJVPl9

The miss rate on Navi22 under FHD is ~22%.
It grows to 47% under 4K, so in relative terms N22 will have to access the .. pic.twitter.com/RZsThb2180
Next gen is certainly going to be interesting.
