I can tell, because you obviously didn’t read:
> the 11980HK is clearly allowed to go to much higher power levels than the M1 Max, reaching package power levels of 80W, for 105-110W at the wall
Meanwhile the M1 max:
> In multi-threaded scenarios, the package and wall power vary from 34-43W on package, and wall active power from 40 to 62W
So it’s over twice as fast (2.2X), at about 1/2 the power - hence Anandtech’s conclusion of “about 6x perf/watt”.
It’s ok, you can still complain that obviously a higher clocked processor should have lower efficiency, and Anandtech addressed that too, in the very next sentence!
> The performance levels of the M1 Max are significantly higher than the Intel chip here, due to the much better scalability of the cores. The perf/W differences here are 4-6x in favour of the M1 Max, all whilst posting significantly better performance, meaning the perf/W at ISO-perf would be even higher than this.
Yep, that’s the picture. Lose by a factor of 2.2X in performance and by a factor of 2-3x in power consumption, or lose by a factor of 4 in performance (made up number but probably about right) at equal power.
Apple is way out ahead here, far more than can be explained by “being a node ahead” or “using tighter pitches”. Their design is ahead.
