> AMD says this delivers groundbreaking capabilities for thin-and-light laptops Laptops with 120W cpus aren't thin or light.

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

  AMDs slides say 45-120W.

    Base TDP is 45. I think you could go below base, if you really wanted, but AMD wants you to design for 45.

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.

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."

  Like a SFF desktop with a big 140mm fan on top. Here's hoping.

    Yeah. I'd love to have one of these in mini-ITX or micro-ATX form. I wonder if at this point, NVMe further becomes a bottlenecking factor?

      Seems unlikely, at least for any normal use case. PCIe 5.0 (the current standard that is widely shipping) has 16GB/sec in each direction (32GB/sec total) with a x4 connection. Doubly so that for the last decade or so memory sizes haven't increases. Seems like the vast majority of machines these days are 8-16GB ram and have a max of 64GB ram unless you are buying workstation parts. How many times a second do you need to load 100% of ram from storage? At least the strix halo supports 128GB of ram.
