It's fairly well known that APUs especially benefit from faster RAM speeds moreso than rigs with dedicated GPUs. It can be harder to come by details for specific APUs so as to make the best value decision about which parts to buy. Some outlets have laid out the benches comparing say 1600/1866/2133 for one APU, but often reviews will simply note that faster RAM enhances the performance and move on without detail.

I don't know how much hardware HH has, but I'm always eager to see those comparisons. As long as AMDs processors stay on the market, that's some fairly evergreen content that can drive search traffic for years.

i think this video from jayztwocents shows the advantage of different ram speeds but in general after a certain speed you dont benefit as much. http://m.youtube.com/watch?v=Cv57qDXpEPU

I've seen other tests with consistent 20%~ gains all the way up. IMHO, the limited numebr of non-casual benchmark based tests makes this good content for HH to develop.

I don't follow. Did I mistype something or was that some kind tagging the forum supports, or?

in general increases in ram speed is good but the price to performance drops out at ddr3 1866mhz as ram that is faster gets a lot more expensive.

That doesn't sound true, and I was just shopping for RAM last week.

example, newegg right now g.skill ares ddr3 8GB (2x4GB): 1600 $37, 1866 $38, 2133 $39, 2400 $45. And that's without deal watching. Even $6 for that last jump is a good value if you could get a 20% boost in FPS. Try getting that with a processor $6 more expensive.

if you dont care which brand you could actually save money btw ddr3 1600 2x4 kit 31dollars. 40 bucks for ddr3 1866 and same with 2133. honestly get a ram brand you trust and get the fastest supported one for your mobo that you are willing to pay for.

You said gains in the post above mine, and I was referencing a meme: http://www.urbandictiona...om/define.php?term=Gains

Thanks, I was not familiar with that meme. I tend to believe that if a meme doesn't come with a picture of a cat, it's just not trying hard enough.

Slow memory is perhaps the biggest inhibitor of integrated graphics performance, since built-in GPUs generally rely on shared system RAM to do their job. Discrete graphics processors have their own dedicated pools of memory, often composed of the latest technologies attached to very wide interfaces, enabling hundreds of gigabytes per second of throughput.

We're thrilled, then, that the Trinity design's memory controller supports data rates up to DDR3-2400. Although 19.2 GB/s per channel is quite a ways off from the 288 GB/s you get from a Radeon HD 7970 GHz Edition's 3 GB of GDDR5, every little bit of bandwidth helps, particularly in games. And that's what we'll be testing today.

I plan on upgrading my RAM just so I can use my APU better :P

Today we’ll see just how much extra performance can be gained by pushing the components past their rated specs on this particular build, and attempt to answer at least a few of the many questions about APU gaming. Of course, this is not a perfect study, and there might be faster or less expensive options out there for any of the components chosen here. The scope of this article is limited to one system, but will serve to show how memory bandwidth can affect gaming performance with an APU.

Mantle results in Thief or BF4 would have been welcomed here, to see how much the combination of faster RAM and Mantle helps with the average and maybe more important, with minimum frames. Or maybe just to see if faster RAM has the same or different impact under Mantle compared to DX11.
