But you'd also keep each half of the M1 ultra under the limit. I'm not saying it's a good idea, because they'd have done it if it was. They clearly know what they're doing. I'm just saying that it's not an absolute blocker for a design you'd otherwise be connecting over something like EMIB anyway.

... three days later ... Oh, I see: you are wondering why Apple M1 Ultra, as two chips linked by EMIB, couldn't just be the two chips adjacent on the wafer. See the difference? Apple knows what their yields are; if they could be sure to get two matched SoC M1 Max chips right next to one another on the wafer, they could punch that pair out and bypass the whole EMIB thing. I don't know enough about testing and dicing 100-billion-transistor chips to know how expensive that would be.
