Amd in general has allowed their mobile cpus to power scale. I don’t see why this would be any different. 15w on the go. 120 with plug

Edit: per article these are positioned from 45w up

FTA (emphasis mine):

"All of the AI Max chips have a 55W base TDP, but also a configurable TDP that ranges from 45 to 120W to unleash more horsepower in designs that can handle the thermal output."

The quoted tdps seem to be for CPU+GPU combined and these SKUs have huge increases in GPU size (40 CUs up from a max of 16 last gen). The M4 Pro and M4 Max fall into the same tdp range.

That's for both CPU, supposedly no-longer puny iGPU and the NPU. You'll get ≥80% real-world throughput for about half the power budget which is can easily be cooled in a 14" laptop that's thin for a gaming laptop without shattering your eardrums. I'll grant that you'll have to pick between acceptable acoustics, thermal throttling, or form factor when you go beyond 60W continuous heat output.
