I find it interesting that the dies aren’t completely identical like Zen chiplets are. If I am reading the diagram correctly, it looks like the tiles diagonal from each other are the same. Kind of neat that they’ll have left-hand and right-hand wafers.

I wouldn't read too much into such a simple diagram. Early on a lot of people thought Epyc had mirrored dies but they're actually all the same.
Sapphire Rapids is confirmed to have mirrored dies, it’s not just a block diagram.

This is to make routing easier on packaging as well as optimize motherboard layout when it comes to memory, power and IO.
