A fabrication disadvantage of this approach is that the four chiplets are actually all different layouts, while AMD uses only two different CCDs (Zen 4 and 4c)

- jeffbee 3y agoIsn't it two different layouts, not four? It seems like on the diagonals they are just rotated.
- formerly_proven 3y agoWhy yes indeed. Still, that's two each of two different ~400 mm² dies instead of just one type of ~70 mm² CCD. AMD also has the IOD of course, which iirc is also around 400 mm². Everything about the Intel solution looks and feels more expensive to make either way.
