What I want to know is approximately the amount of latency induced by PCIe and by RAM? I want the latency from the CPU to the DIMM slot and to the PCIe slot (so no round-trip latency).
I was just curious.
Also, are those memory latency from the CPU and back or are they just CPU to RAM? (This is because I found it is about 100ns (in 2010) to access the DRAM (so CPU to memory) (https://stackoverflow.com/questions...cost-to-access-various-caches-and-main-memory)).
Also, by any chance, do you know the approximate latency of PCIe?
