The chip itself is becoming a NUMA-like system, with its own internal
network, a crossbar switch and its own internal topology. At some
time, if the number of cores continues to grow, it wouldn't be that
surprising to see some locality emerge, in the form of local clusters
of cores, tightly coupled on a bus ring, 


Kilian, I agree.  I was just being a bit jocular about the complexity of this thing.
Yes, it’s a little NUMA system on a chip - which is quite exciting really.
Take a four-socket one of these, and a bucketload of RAM, and you have a pretty nice
personal system.
