Bill. AMD Zen's architecture is like it is.
They use a lower density design "uncore" in the middle.

I/O does not need as high density processes and often consists of mostly large contact pads.
If you use a lower density process, which likely has better yields, and has less demand, then you get better cost effectiveness this way.
