Except that they are much larger chips, that will be much more sensitive to yield issues. They could do that, but they will be expensive. Maybe that's ok.

- cma 4y agoTheir biggest (m2 max in studio) are more like chiplets with interposers, which exponentially lowers the yield problems depending on how much you can split it up. Also larger chips can still set a threshold on gpu cores to disable due to defects and that kind of thing, where a mobile one might just throw out the chip with a much lower number of (or any?) defects. Nvidia can make tons of tiers out of the same chip by just setting different thresholds on the number of usable cores, it isn't all just price discrimination (though sometimes I think they have been found to be fusing off much more than needed for the number of defects as a pure price discrimination play, or that might have been Intel with cache size).
- BackBlast 4y agoM2 Pro/Max chips will be huge. Only the ultra is using an interconnect between dies, but that's two full max dies. M1 Max is 432 mm^2, that's enormous. M2 is 25% bigger than M1. There's not a lot of lower core count SKUs for these chips either. There's a few GPU tiers and CPUs tiers but not lots of room to go down. Pro has 8/10 CPU cores and 14/16 GPUs. Max is 10 CPU and 24/32 GPU. There is no 4-7 CPU core segments like AMD does with their chiplets. Intel has much lower tiers for their dies. The dies are just huge huge huge.
