![]() ![]() The extra capacity reduces how often the CPU has to pull data out of the relatively slow system memory, which is why faster RAM didn't make a big difference.Īlso read: AMD explains how the new 3D V-Cache improves over the original The reason for the 5800X3D showing such a small improvement was entirely down to the larger 元 cache. We did notice that in more demanding games, the margin could be as high as 5%, but that's still not much of a difference. In testing, we found that going from DDR4-3200 to DDR4-3800 (a 19% increase in speed) only improved performance by 2%, on average. ![]() The best solution to this was discovered when AMD introduced the Ryzen 7 5800X3D, the first model to employ an additional 64 MB of 元 cache, stacked on top of the standard 32 MB, giving an enormous total of 96 MB. This is an issue for AMD, as Intel's Raptor Lake architecture isn't nearly as sensitive to memory speeds and timings. It's no different with the current Zen 4 architecture, with the Ryzen 7 7700X being extremely sensitive to memory bandwidth and latency, seeing on average 17% greater gaming performance using DDR5-6000 C元0 as opposed to DDR5-5200 CL40. When we carried out this type of test with the Ryzen 5 5900X, in the games that tasked the CPU the most, going from standard DDR4-3200 CL14 to manually tweaked DDR4-4000 CL16, the average frame rate increased by as much as 16%. So it's time to see how the Ryzen 9 7950X3D fares when using a variety of memory kits, with different bandwidths and latencies. Using faster RAM could give a sizable increase in gaming performance, especially in cases where the game is very CPU-demanding. Ever since AMD introduced Zen, all CPUs based on the architecture have shown that they are especially sensitive to memory speed, as well as other timings.
