But that's also for something which has a TDP of 125W [2], unsure if that's the right number for a mobile chip? Also no clue what M1 Max's TDP is either.
M1 Max TDP will be around 30-40 watt for the CPU cluster and 50-60 watt for the GPU cluster. Note that unlike x86 CPUs (which can draw far more than their TDP for brief periods of time), this is maximal power usage of the chip.
M1 needs about 5W to reach those signs-core scores, Tiger Lake needs 20W
12900K has 8 high performance cores (with 2 hardware threads each, look up hyperthreading), and 8 efficiency cores for a total sum of 24 hardware threads.
Previous Intel generations have only had so called high performance cores (except, maybe, for the Atom line of CPUs), even though not all of them have had hyperthreading enabled.
The points per watt is probably going to be crap but equally I don't care all that much.
One thing as well is that there are always headlines complaining about power usage, but the figures are nearly always from extreme stress tests which basically fully saturate the execution units.
Geekbench is slightly different to those stresses so not sure.
