I think only Strix Halo will be three nanometers. They need that shrink to save power for the huge GPU! Also, i think Strix Halo might be only for oem (console, handheld) partners - i dont think it will be available for laptops or mini PCs, we'll have to wait and see about that ...
Who do you think makes laptops and mini PCs?
Strix Halo is for
laptops before anything else, challenging laptops with dGPUs, which are expensive products that can use a lot of power. They are often treated like desktops and plugged in constantly.
It may do well in handhelds, but it could use more power than desired to get good results. We will have to see about that one. I don't see it being relevant to whatever non-handheld "consoles" means. It won't be found in a PS5 Pro for instance.
If you are right about Strix Halo using TSMC N3 chiplets for the CPU, that would be exciting. I think there was a rumor that Strix Halo will use all Zen 5 cores, but not the same chiplet as Ryzen 9000. If that's true, then the interview answer about Zen 5 on two nodes makes much more sense. But I still think it could refer to Zen 5c on 3nm.
I can see AMD following Intel with core counts for consumer market, at some point performance cores will standardise probably at 6 or 8, with or without HT, at higher clock speeds and it will be the efficiency cores that will increase in number definitely with HT and at will be speed capped with very tight variable power usage.
8 performance cores needs to be easy to get to, if not the minimum. After that, slower cores are going to be fine for most. This is at least true until a couple of years after the release of next-gen consoles.
