Looking forward to how AMD is gonna manage to improve both raster and RT performance with RDNA 3 without a smaller process while still keeping up with Nvidia. Next gen will most likely see SAM across the board, which currently is the only saving grace for AMD.

I guess they'll have to scrap their cache and use actually fast memory to make some room.

After RDNA2 I'm not expecting much from RDNA3, amd have stated they are aiming for another 50% Perf/W increase. It's supposed to be released the end of next year.

How they are gonna increase Raster and RTX performance? I thought you and Pemalite had a lot of ideas, the Macos leak suggests that RDNA3 top-end card still has 80CU's. The best way is to achieve another 1.5x performance increase is just to increase IPC by 25% and clocks by 25%, or they can do same trick as Nvidia did, go 128 gpu cores for each CU.

I'd be amazed if they manage to increase both IPC and clocks at the same time. While knowing nothing about RDNA3 I can only assume that they will actually decrease clocks in favor of going wider and improving IPC. Unless of course they still don't want to compete at 4k.
