At frequencies of ~1333 MHz. - the default for AMD PII CPUs, there is no tangible gains with either lower latencies or increased frequency - per the link I posted and testing by Tom's Hardware, AnandTech and X-Bit Labs, to name a few sources who have done extensive testing on both AMD and Intel desktop PCs.
If you want to see true changes in performance use Real Applications, not synthetic benches
as they do not 100% represent real apps. The link I posted has Far Cry 2 results from "damric" showing only a 3 FPS gain @ 36 FPS, with a 50% RAM OC to 2000 MHz. with an FX 6100 CPU. It's unfortunate that there are no significant gains with higher RAM frequencies in AMD or Intel desktop PCs but it's understandable when you realize that DDR3 RAM @ ~1333 MHz. is not a system bottleneck and as RAM frequency increase one clock cycle in real time becomes less and less so tighter latencies mean little. It's worth noting that some folks disagree on what is a "significant gain in real apps." so if 1-3 FPS @ 36 FPS is significant to you, then you'll be thrilled to death with the insignificant gains.
As always: I recommend that people buy what makes them happy
. The tech info. referenced is for educational purposes. It will help you understand why you don't see tangible gains in real apps. with the higher clocked RAM.
BTW - The Llano APU is the one exception as the GPU does benefit from the higher RAM frequency.Edited by AMD4ME - 4/6/12 at 10:54am
