The 3080 and 3090 are pushing 800 GBps or 900GBps VRAM bandwidth (Gigabytes, not bits). They're absolute beasts. Seeing the 500GBps VRAM bandwidth on the 6900xt or 6800 xt makes me think that they couldn't just keep up... but that 128MB cache is clearly key.
They've got the thing working on a wide variety of games (if they're publishing those FPS numbers already). So the cache has to be transparent. I wonder what the rules are for it: 128MB seems too small to hold much texture or vertex information. So I wonder how it helps.
This 128MB cache intrigues me.
