CPU will still out-perform this memory as current CPU are generally what 4 cores with somewhere around the 32Ghz combined data link speed (talking to memory) where said memory is topping at approx. same speed as the QPI link allows it PLUS effective latency effect 3200 class DDR4 "peak transfer" is 25.6GB/s, so maybe 1/3 slower actual speed then what the processor can use taking into account the latency, the memory simply will not outpace the available speed the cpu can use, cpu is the FASTEST part in a computer system as it is what does the actual "work" and everything even "spinning" at the same speed still relies on it so therefore introduces latency to the mix so the cpu generally is still "waiting" not being outpaced.
Granted A DDR4-3400 class speed is the current "cream of the crop" DDR4-4800 is max that will eventually see the light of day pushing the current fastest memory sub-system to the limit which would give a "peak speed" of 38.4GB/s where the fastest DMI/QPI/HT link set I can find is somewhere in the area of 51.2GB/s theoretical max for both Intel and AMD at this point, though I do not believe either uses this let alone about the only place this would truly see a "use" is in a professional balls to the wall environment.
So blazing fast, crazy expensive, and insane latency with great looks check "{
