  BTW, what actually is “Strix Halo” anyway? I’m confused about whether it’s what they’re calling all the latest-generation APUs, or just the high-end ones, or Asus co-branding, or what.

  Strix Halo is the “high-end” ones (and currently the latest), in terms of gaming they are closer to previous gen discrete GPU (hence they use the naming scheme Radeon 8XXX series).

  There are smaller ones as well, the one that is “mid-tier” is Strix Point, which has the Radeon 800M series GPU, i.e. closer to what one had in previous generations of integrated GPUs.

  In terms of gaming performance, you can compare using Notebookcheck, as an example; Kingdom Come Deliverance 2 on low preset at 1080P:

  CPU	GPU	Average FPS
  Ryzen AI 9 HX 370	AMD Radeon 890M	19.9
  Ryzen AI Max Pro 390	AMD Radeon 8050S	76.6
  Ryzen AI Max+ 395	AMD Radeon 8060S	101.7

  So, there’s a pretty big leap going from Strix Point (mid tier) to Strix Halo (high-end)

  I would assume the total area is larger for the separate CPU+GPU die when compared a single unified chip, sure. But the cost per millimeter doesn’t necessarily scale linearly either (larger chip, lower yields), so it might be cheaper to buy CPU+GPU rather than the unified chip even though the total area is larger.

  For reference, TechPowerUp lists:

  RX 7600M: 204 mm² @ TSMC 6 nm Strix Halo: 308 mm² @ TSMC 4 nm

  Not sure what kind of area one could expect for the CPU alone (without the integrated GPU) for this kind of process

  Custom in this case doesn’t really need to carry any weight either, it could be a simple voltage bump, clock bump, laser cutting cores etc. and they would still call it custom.

  It’s not a “from the ground up” custom chip. Unified still requires a significant amount of chip area per die, especially if they want to have a relatively beefy GPU (somewhere below Radeon 8060S, but above Radeon 780M).

  I would imagine this gives the best perf./buck from Valve’s POV, without costing an arm and a leg

  I don’t think there are any ‘cheap’ Strix Halo chips out there, Valve probably got a massive discount (relatively) by using previous gen. laptop parts
