Why? Isn't the interesting metric the number of cores, rather than the number
of fully-independent CPUs? It's the number of cores that determines how many
concurrent threads you can have; the fact that some of your cores are on the
same CPU die is mostly an implementation detail.

(For instance, an old server with two separate Pentium II CPUs, and a modern
laptop with one dual-core CPU, could each run two threads at a time.)
