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.

According to AMD, it will be much less expensive, yet will have plenty of […]
