Is DDR3 2133 11-11-11-31 better than DDR3 1600 9-9-9-27?

[Guest]

I would like to know if the DDR3 2133 11-11-11-31 (G.Skill Ripjaws) is better than my current DDR3 1600 9-9-9-27 (HyperX)? In general, do we have a way to compare 2 ram sticks based on speed and timing just by looking at numbers?

Thank you.

Yes, from a purely performance standpoint they are about equal, but the higher bandwidth of the 2133 allows for more to be used at a given time, if you were to downclock the 2133 to 1600 it would run at about the same 1600/9 but you lose the additional bandwidth

The higher speed of 2133 makes it a little better
But the performance between the two is nothing you'd notice other then in benchmarks

Can you elaborate more about the additional bandwidth? Do you mean if multiple programs access memory at the same time, the 2133 will handle better (and the system is more responsive) than the 1600?

If I can remember how to read those numbers correctly, the 2133 will work faster, but it will have 4 additional 'wait' cycles of 4.6*10^-10 seconds between read/write commands. Performance will be very similar I believe.

Yes, when running 1600 you are using 12,800 MT/s (mega Transfers per second) of DRAM - the higher data rate (2133) runs up to 17,000 MTs so you have more DRAM working

Will the looser timings have no bearing on the end result?

Does it also affect the Intel integrated graphics?

I believe so, yes because the integrated graphics uses your system RAM to buffer textures. I question, however the noticable difference because as you may know high-end video cards use GDDR5. I am not sure, how well that translates in terms of DDR3. There should be a benefit, yes, how much? I can not say for sure, There are benchmarks if you want to google it. Faster RAM theoretically SHOULD net you an FPS increase when using integrated graphics. Hope that helps

Timing vs performance doesn't really change much as you are running the wider bandwidth, as far as integrated graphics, the iGPU uses system memory so the faster the better there
