On a related note, check out the diagrams in the associated article:

Yikes! Nehalem without a Quick Path Interconnect. And the memory
controller is right on the same die as the CPU. I haven't seen
innovation like this since Alpha EV7. Alphacide was in 2002 so it only
took Intel 7 years to finally get where Alpha was. Ah, if only Carley
and Curley hadn't been seduced by the shadows (sorry, I'm re-watching
5 years of Babylon 5)
