2 sockets can allow a server to hold 32 or more cores, and a 2 socket server uses 1U of space. Going to 4 or more sockets typically requires 2 or even 4 Us of space, so they’re less efficient space-wise. Most people dealing with hardware don’t refer to “CPUs” anymore, because there’s a lot of confusion around sockets, cores, and hyperthreads, so it’s better to be more specific in any conversation.
