Current architecture on mother boards (except for high-end) stuff does not support multiple channels to memory or multiple memories.

So we have the bottleneck for performance being transferred from the processor(s) to the memory system, and to the I/O systems.

It reminds me of through-put studies for a ticket booth.

With a single queue, are you better off with one server working at speed 2X or two servers working at speed X?

Actual measurements and queuing theory algorithms say, faster processors, but fewer of them, are the better answer.
