Only in single-core performance and performance/watt, and the advantage the M1 has in both of these metrics is pretty much exactly the difference expected between a 7nm and a 5nm process (they’re both being produced by the same fab, after all).
It’s likely we’ll see Apple and AMD compete on pretty much equal terms in the CPU market in the future.
- deergomoo 6y ago> Only in single-core performance and performance/watt I mean, the Ryzen besting the M1 in multi-core performance isn't really surprising when you consider that it's a 16-core/32-thread, 105W desktop CPU vs an 8-core/8-thread (four of which are low power cores), ~25W fanless laptop CPU (looking at the 5950X from the Anandtech review).
- izacus 6y agoYes, but you need to look at performance per core / W. The power draw of AMD cores is higher, but not by a lot.

Maybe, maybe not. There's no reliable way to estimate exactly how much improvement AMD would get from moving their design to the same fabrication process that the M1 is using.
