M1 with all its CPUs pegged to 100% only hits 20W, so M1 still uses way less power than single core in Zen.
Edit: In fact I just ran Cinebench R23 single thread test and package power barely crossed 5W.
- scoopertrooper 6y agoYup, the MacMini M1 maxes out at 10.5W on single threaded workloads https://www.anandtech.com/show/16252/mac-mini-apple-m1-tested https://www.anandtech.com/show/16252/mac-mini-apple-m1-teste...
- imtringued 6y ago> M1 with all its CPUs pegged to 100% only hits 20W, so M1 still uses way less power than single core in Zen. So do Ryzen CPUs. The 16 core Ryzen only needs 5W per core. It's purely a matter of frequency management. These comparisons are meaningless because you can say stupid things like "Ryzens are more power efficient than Ryzens" and still be right.
- my123 6y agoAt 5W per core, you don't get anywhere near the single-threaded perf needed to beat an M1... (20W per core is what it reaches on ST tests, with 17W more for the I/O die on desktop Ryzen, an overhead that'll be much lower on Cezanne hopefully)
