This is on the same 7nm process as RDNA1 was, but with an over 50% (65% for the top-end 6900XT) performance/watt increases, so this absolutely isn't just about

This is on the same 7nm process as RDNA1 was, but with an over 50% (65% for the top-end 6900XT) performance/watt increases, so this absolutely isn't just about process (although having high yields is key to overall product success). I'd say the crowning achievement for this architecture is the "Infinity Cache": https://twitter.com/Underfox3/status/1313206699445059584 https://twitter.com/Underfox3/status/1313206699445059584 "This dynamic scheme boosts performance by 22% (up to 52%) and energy efficiency by 49% for the applications that exhibithigh data replication and cache sensitivity without degrading the performance of the other applications. This is achieved at a area overhead of 0.09mm²/core." See also this presentation: https://www.youtube.com/watch?v=CGIhOnt7F6s https://www.youtube.com/watch?v=CGIhOnt7F6s
