    Corps aren't your friends. "Bottleneck calculators" are BS. Only suckers buy based on brand. It's your PC, do what makes you happy.  If your build meets your needs, you don't need anyone else to "rate" it for you. And talking about being part of a "master race" is cringe. Watch this space for further truths people need to hear.

    The difference is about one tick. 

     

    In the performance world, roughly .5ns latency difference average. (Guestimate) bu even the latency difference would matter to the rest of the timing set, ram frequency, cache, frequency and Infinity Fabric frequencyand cpu frequency taken at the time of measurement.

     

    So each timing could produce essentially the same latency depending on a bunch of other factors involved.

    would it make a big diiffrence between 16 and 18? also why does ddr3 have less?

    Not really a huge difference no. If you are on the quest for performance, that's a different story. 

     

    DDr3 is a lower frequency, and thus a lower latency. 

    DDr4 is much faster and requires looser timings to accomplish it. 

    DDr5 will be faster yet and will have much looser timings sets as a result. 

    It's just the nature of physics I guess....
