All. Keep in mind strix != strix halo.

You can get tablets, laptops, and desktops. I think windows is more limited and might require static allocation of video memory, not because it's a separate pool, just because windows isn't as flexible.

With linux you can just select the lowest number in bios (usually 256 or 512MB) then let linux balance the needs of the CPU/GPU. So you could easily run a model that requires 96GB or more.

> What Strix Halo system has unified memory?

All of them. The static VRAM allocation is tiny (512MB), most of the memory is unified
