Intel wants to launch the new Raptor Lake processors in a good two weeks, which are supposed to compete against AMD’s new Ryzen 7000 CPUs as Core i-13000. The new flagship, the Intel Core i9-13900K, is expected to have more E-cores and a slightly improved manufacturing, among other things. According to the known specifications, the memory controller has also been revised: It should be able to drive significantly faster RAM.
DDR5-7600 and more
This difference already becomes clear with a look at the specifications: According to this, the Intel Core i9-13900K will support DDR5-5600, whereas the Intel Core i9-12900K is officially only suitable for DDR5-4800. However, the memory controller is apparently far from the limit with this: Intel has published a list with XMP-3 profiles, according to which the flagship has been reliably tested with a DDR5-7600 profile.
Specifically, an i9-13900K was run on an Asus ROG Maximus Z790 APE, which in turn had two DDR5 bars from G.Skill (F5-7600J3648G16GX2-TZ5RK) installed. Thus, the CPU ran with DDR5-7600, 1.4 volts and the timings 34-42-42-84 thanks to XMP. In addition, several other configurations can be found in the list, in which the new Raptor Lake processor was combined with DDR5-7466 or DDR5-7200 memory.
So, at least some Raptor Lake processors will probably be able to run with significantly faster memory than the specification without manual overclocking. Moreover, Intel has already held out the prospect that it should even be possible to run with DDR5-10000 and more through manual overclocking. However, it remains to be seen how much such memory speeds will bring in practice: The first official tests will have to show that.
