- 6nm would bring 18% higher density (so more dies per wafer) + some performance or efficiency improvements as AMD chooses to tune the dies (Performance for desktop/Efficiency for laptops I suppose).

My understanding is that 6nm is a clean shrink of 7nm without the complexities and overhead of a full node shrink.

Wonder if AMD will end up running a couple simultaneous lines: 7nm for their 6000 series mainstream and bulk cards, 6nm for their mid to top end 6000 series S cards, and eventually 5nm for their RDNA 3 top end parts. Shift everything down a tier when 4/3nm whatever show up.

RDNA2 AVERAGE frame rates don't scale much with memory overclocking. However, 1% lows DO gain a notable amount from faster VRAM. Cache misses do hurt. Texture loads do take a nontrivial amount of time. Both of those are heavily dependent on VRAM speed.
