where did you come up with the 12900K pulling 50W? The 12900K is a 240W-class processor at full boost, so the M1 is pulling 1/6th the power...
(the 12700K is much more reasonable but the 12900K and 12900KS are a "win the benchmarks" SKU and intel turned everything to 11 to get it over the top of the 5900X.)
