Why does CPU=8 in Intel Core i9-12900K have fast access to all other cores?


This Content is from Stack Overflow. Question asked by moep0

This is the original tests. The figure shows that CPU=8 in Intel Core i9-12900K has fast access to all other cores.

Therefore, I am wondering what makes it happen.

Besides, I am also curious about the yellow part in the same figure. Why the core-to-core latency in the same E-core cluster is larger than in the different clusters?
