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 …

Package power delta for 0 to 1 core loading on M1 is ~10W peak, ~25W for the Ryzen, though the author undervolted it so it might be lower. Core power deltas seem to be closer to 6W for M1, 17W for the Ryzen (guessing from the non memory intensive test for the M1).

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.

Loading seems to be taking a while.
