The difference isn’t huge, but then why would you buy 4,000MHz RAM over 3,600MHz RAM if it’s slower at all? You wouldn’t, and you’ll save a few dollars too. This incurs a latency penalty that we see in the data, with DDR4-3600 generally being slightly faster than DDR4-4000. If you move beyond this, the motherboard will automatically set the Infinity Fabric clock to 1:2, or half the memory speed. Well, actually it's 3,733MHz if you really want to push it as far as you can go. The memory clock and Infinity Fabric clock are tied to each other in a 1:1 ratio up to a speed of 3,600MHz. Very fast memory doesn’t make much sense on a Ryzen 3000 CPUĪs we mentioned above when looking at the latency results, we see one of the quirks of AMD Matisse CPUs reveal itself above DDR4-3600. If you shift to 1080p at maximum settings, you are presented with more of a graphics bottleneck, and at 4K at maximum settings, even an RTX 2080 Ti can and does struggle to put out playable frame rates in some titles. A fast CPU-and as we’ll see-quality memory are also necessary. If you’re gaming at 120 fps and higher, you need more than a powerful GPU. This covers a good chunk of use cases.ġ080p results at low settings give good information for gamers using high refresh rate monitors. We’ve tested at 3 different settings: 1080p at low settings, 1080p at maximum settings and 4K at maximum settings.
