I think in a broadcast snoop cc system, then the bisection bandwidth of the snooping interconnect is more important than just the number of links to a node (although the latter can influence the former of course).

Istanbul is rather crippled by its L3 cache size. 6MB total, 1MB per core. 8 core Nehalem has 3x this much per core, and relatively more than other Nehalems -- not surprising as this is an *MP* server part. Cache just really helps larger systems to scale on smaller interconnects. No prizes for guessing why POWER and IPF CPUs have massive LLCs.

I'm surprised you didn't mention it in your article.
