Another benchmark, M1 vs Ryzen 5800X on single threaded workloads. Ryzen wins the benchmarks, but the M1 has better perf/watt.https://github.com/tuhdo/tuhdo.github.io/blob/master/emacs-tutor/zen3_vs_m1.org …

But that Ryzen is definitely not optimizing for perf/watt. The 5600X is only ~5% slower on clock but ends up on ~17W package, ~12W core delta. So again I'm getting a bit of a "meh" feeling here.

I think if AMD moved to 5nm and put out an APU with the same design targets as the M1, they could hit comparable results. But Apple has been improving their chips at a ridiculous speed... So the real question is what will happen on their *next* generation.

TSMC 7nm+ (introducting EUV) is indeed optimised for performance and not really for power efficiency and AMD are definitely designing for that. TSMC 5nm EUV that the M1 uses has a massive 30% power improvement over 7nm.
-
The Zen chiplets definitely are geared for performance. But the APU dies, especially post-M1, I can see going more for efficiency after this. I also wouldn't be surprised if AMD K12 (Zen's ARM sister) starts up again.

I think the future looks better for arm as it is new and still can evolve a long way. x86 is old, dated, stuck, and can only move forward by improving nm size, but that's all it can do. Arm still has plenty of room to grow

But isn't AMD not even fully on 7nm yet since the IO chip, which takes quite a bit of space, is still 12? So even if Apple iterates fast, AMD has lots of headroom to work with.
-
Yes, but the per-core numbers are largely for the 7nm chiplets, so you can mostly ignore the IO die issue for that side of the equation.
