True it won't affect latency. Yet caches are pretty good at ensuring most DRAM requests take advantage of the hardware parallelization available. That’s why despite DRAM having pretty much constant latency for the last 20 years bus speeds and bank counts have been consistently increasing. Optical interconnects will help immensely. We may also see things like off chip SRAM come back into vogue once its feasible to take advantage of their performance.
