I also wondered about binning, so I pulled together how heavily Apple's Max chips were binned in shipping configurations.

M1 Max - 24 to 32 GPU cores

M2 Max - 30 to 38 GPU cores

M3 Max - 30 to 40 GPU cores

M4 Max - 32 to 40 GPU cores

I also looked up the announcement dates for the Max and the Ultra variant in each generation.

M1 Max - October 18, 2021

M1 Ultra - March 8, 2022

M2 Max - January 17, 2023

M2 Ultra - June 5, 2023

M3 Max - October 30, 2023

M3 Ultra - March 12, 2025

M4 Max - October 30, 2024

> My guess is that Apple developed this chip for their internal AI efforts

As good a guess as any, given the additional delay between the M3 Max and Ultra being made available to the public.

I’m missing the point. What is it you’re concluding from these dates?

I was referring to the additional year of delay between the M3 Max and M3 Ultra announcements when compared to the M1 and M2 generations.

The theory that the M3 Ultra was being produced, but diverted for internal use makes as much sense as any theory I've seen.

It makes at least as much sense as the "TSMC had difficulty producing enough defect free M3 Max chips" theory.

Gotcha. Thanks!
