On Socket AM4, it took just a few generations for AMD to get its reminiscence controller efficiency all maxed-out. The unique Ryzen struggled with DDR4 reminiscence quicker than about 2667 MT/s, and it wasn’t actually till Zen 2 (the Ryzen 3000 sequence) that we began to see extensive help for reminiscence quicker than 3000 MT/s.

That’s all up to now now, after all. Modern Ryzen machines normally don’t have any issues taking a pair of modules as much as DDR4-3800 or greater—though going past that normally requires decreasing the Infinity Fabric clock, which makes the nominal enhance in reminiscence bandwidth a lot much less helpful.

AMD clearly intends for the launch of Socket AM5 to don’t have any such points. The firm already bragged that its upcoming Zen 4-based Ryzen 7000 CPUs must be fairly adept reminiscence overclocking. Indeed, in its personal documentation, the corporate has apparently been testing pre-release silicon with reminiscence clocks as excessive as 6400 MT/s. That’s totally one-third greater than the reminiscence spec for Intel’s Alder Lake CPUs, which mandate DDR5-4800.

The Ryzen 7000 sequence processors certainly will not be spec’d for such a excessive reminiscence clock, however early rumors appear to place these processors down for 5600 MT/s, a minimum of for the fanatic desktop components. We can anticipate that for its Thirteenth-generation Raptor Lake processors, Intel will enhance the reminiscence velocity past Alder Lake’s first-DDR5-generation minimal, however by how a lot?

We might have a clue as to how a lot within the type of the spec sheet for an industrial motherboard. MiTAC, often known as MCT, listed a really curious entry within the specs desk for its PH12ADI Mini-ITX motherboard. This board may be discovered with an H610 or Q670 chipset, and usually it takes DDR5-4800 reminiscence in SO-DIMM format.

Well, till this morning when @momomo_us pointed it out, the motherboard additionally listed help for 5200 MT/s on Raptor Lake-S chips. The point out has since been eliminated, so because of @momomo_us for the screenshot. No doubt Intel was fairly irritated at MCT for revealing this little little bit of trivia about its upcoming CPUs.

Of course, that does not imply that Raptor Lake will essentially be spec’d for 5200 MT/s. It actually doesn’t suggest that the longer term CPUs can be restricted to that velocity; intrepid overclockers have already taken an Alder Lake CPU to 10,000 MT/s. No doubt the Thirteenth-gen CPUs will push ever farther previous that boundary.
