That’s just marketing fluff in terms of measurements. Most agree that in terms of gate size, intel’s 7nm is similar to TSMCs 5nm. So you could say that Intel moving to 5 would give them a 30% boost but the TSMC goes to 3nm.

Intel renamed their nodes, "Intel 7nm" is what they were previously called "Intel 10nm". So the node numbers are now (semi) compatible between Intel and TSMC.

To be clear, the node formerly known as Intel 10nm is now called Intel 7. There's no unit attached, which is probably for the best, as what was being measured in nanometers previously was super subjective and varied per manufacturer.
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.
