The Argument For Single-Socket Servers

Joe Chang wants us to think about socket counts:

It might seem that the 2-socket system continues to be a good choice, as two processors with an intermediate number of cores is less expensive than one processor with twice as many cores. An example is the Xeon Gold 6132 14-core versus the Xeon Platinum 8180 28-core processors. In addition, the two-socket system has twice the memory capacity and nominally twice as much memory bandwidth.

So, end of argument, right? Well, no.
