Looking for a new set of RAM

Two out of five game tests, F1 2012 and The Elder Scrolls V: Skyrim, showed us that that both bandwidth and latency can influence frame rates significantly. Both variables appear equally important, too. We might have guessed we'd see the results we did; after all, both titles are already known to be less graphics-bound than the others.

On the other hand, Metro 2033, Battlefield 3, and Aliens vs. Predator demonstrated no changes at all. The performance of the first two titles is most consistently associated with the speed of a given machine's graphics subsystem, so it makes sense that we don't see a big impact from memory bandwidth or timings. And when it comes to the high frame times that impose perceived choppiness, those appear tied exclusively to graphics performance, not memory throughput or latency.

Getting back to the games that were affected by memory performance, only one title exhibited differences significant enough to be noticeable during real-world play. Even then, the average frame rates were so high that your eyes (and displays) would need to be about twice as fast as ours to realize the real-world benefits of faster RAM.

Well, first, you want timings to be LOWER, not higher. Second, you are correct (speed doesnt matter0. In the vast majority of applications and games (that don't use the iGPU) will not benefit much if any at all. Ram bandwidth is not a bottleneck.

Do you think it is worth it to pay more for almost no perceivable gains?
