being desktop doesn't imply AM5. there was a 4-channel threadripper, for instance.
but I was thinking more of a mini-pc, since legacy form-factors don't make that much sense for a high-end APU. being a mini-pc would also make it more palatable to solder on the CPU like a laptop - and of course soldered-on RAM gets to run at higher speed.
Threadrippers exist, but would Strix Halo then use Threadripper sockets? Would it use its own sockets? I don't expect Strix Halo to appear in any socketed form.
I think you're right that it'll appear in SFF PCs, like most of AMD's mobile parts do. And that is pretty exciting IMO.
