Indeed, indeed it does solve that problem, but other actors need to align. Someone would have to ship a CPU that people want that supports off-world LPDDR (i.e. not Intel Lunar/Arrow Lake), and laptop makes would need to adopt it.

My suspicion is what will actually happen is that CAMM2 is going to make inroads in desktop systems.

Seems like you're not aware of AMD's recent APUs, which seem to be very capable and very popular. I'm not sure if a laptop model sporting one with CAMM2 ram is available yet, but one can safely assume it's just a matter of time.

I'm also not sure what you mean by other actors needing to align. JEDEC has standardized CAMM2 already. Which is how all concerned actors accomplish alignment.

I am aware of them but as you pointed out they don't exist with CAMM. The one that I want is the Ryzen AI Max and all the implementations of it so far — the Framework Desktop, the HP Z2 G1a — have the memory soldered down without CAMMs.

I seem to remember executives from Framework being active in the HN comments at the Framework Desktop launch in which CAMM2 support was a highly requested feature. I suspect they received the message.

Lovely thing about the PC industry which differs from our friends in Cupertino is that it tends to explore the full design space over time. All good things come to those who wait.
