If it is not obvious, try this: Again draw 8 small squares, representing cores, on a paper. Now partition them into two groups of four with a dashed line down the middle. Fully connect the cores in each group (6 links each).Do you actually believe you use less with IF connecting 2x CCXs ??
Now you can start experimenting with interconnecting the two groups across the dashed line. Note that at a minimum a single additional link will do. But you will be able to decrease the maximum number of hops between any two cores in separate groups by adding more links. You may add additional intermediate nodes (routers). Draw these as small circles. You are now creating complex topologies (hyper-cube, fat tree, etc.).
