> The Zen3 processor that they are comparing it to is the 5950x - the fastest desktop processor with a TDP of 105W. The entire system power of the M1 mini under load was 28W.
This is a very misleading statement. They primarily only used the 5950X in single-core tests, and in those tests it doesn't come remotely close to 105W. In fact per Anandtech's own results[1] the 5950X CPU core in a single-core load draws around 20w.
Take the M1's 28W under a multi-threaded load, that's going to be somewhere in the neighborhood of 4-5w/core for the big cores probably (single-core was ~10w total, ~6w "active" - figure clocks drop a bit on the multi loads, and then the little cores are almost certainly much less power draw particularly since they are also much, much slower). In multithreaded loads the per-core power draw on a 5950x is around 6w. That's a _much_ closer delta than the "105W TDP vs. ~28W!" would suggest.
M1's definitely got the efficiency lead, but it's also a bit slower and power scales non-linearly. It's an interesting head-to-head, but that 105W TDP number of the 5950X is fairly irrelevant in these tests. That's not really playing a role. Just like it's about as irrelevant as you can get that the 5950X is 4x the big CPU cores, since it was again primarily used in the single-threaded comparisons. Slap 16 of those firestorm cores into a Mac Pro and bam you're at 60w. Let it run at 3.2ghz all-core instead of the 3ghz it appears to now since you've got a big tower cooler and that's 100w (6w/core @ 3.2ghz per the anandtech estimates * 16). That'd be the actual multi-threaded comparison vs. the 5950X if you want to talk about 105W TDP numbers.
Critically though the M1 is definitely not a 10W chip as many people were claiming just a few days ago. You're definitely going to see differences between the Air & 13" MBP as a result.
