alt Hacker NewsIt used to mean that, but the new M5 Pro and M5 Max have separate CPU and GPU chiplets with an interposer, similar to how the previous generation Ultras were based on connecting two Max full dies. So it's unclear whether there will be any Ultra for the M5.

And here I was hoping they would put an M5 Ultra in a MacBook Pro. Maybe they will add it as an option to the 16” at a later date.

This tells me the Max CPU chiplet has two interfaces to GPU dies. If you can connect two CPU chiplets via the same interface, making an M5 Ultra is doable by joining two CPU chiplets, each with a GPU chiplet attached.
