>3.5%-5% increase in performance at more than double the wattage

The 100 watts mentioned in the article is the whole laptop power. Google tells[0] me the power consumption of the i9-12900HK is 45 with boosts up to 86W.

Intel's 12th gen i9 is built on 7nm, Apple's M1 max is build on 5nm. Rule of thumb, is about 30% power saving at same performance for a new node.

So assuming max performance of M1 Max is 40W and i9-12900HK is 86W, adjusted for process node we are looking at 40W vs 60W.
