Intel Raptor Lake-S supports DDR5 at 7,600 MHz and uses its cores more intelligently

The presentation of Intel Raptor Lake-S occurred just a few days ago, and how could it be otherwise we already tell you its most important keysboth in terms of performance and in terms of the innovations introduced by this generation in terms of architecture.

In general terms, we are facing a generation that maintains the base we saw at Alder Lake-Sthat is, it has a block of high-performance cores and another of high-efficiency cores, but at the same time introduces important changes that mark, as a whole, a remarkable evolution.

Intel Raptor Lake-S

Undoubtedly, one of the most relevant advances is found in their performance. Intel Raptor Lake-S processors improve single-wire performance by 15%thanks to the use of the new Raptor Cove architecture, and multithread performance by 41%. This latest leap in multi-threaded performance has been made possible by that cumulative improvement in single-threaded performance and an increase in the total number of high-efficiency cores, which has been doubled across all “K” and “KF” models.

The LGA1700 platform with the 700 series chipset will be the great champion of this new generation of processors, and will maintain compatibility with DDR4 and DDR5 memories. We know that the Intel Raptor Lake-S processors will have native support for 5,600 MHz DDR5 memory, but thanks to the Intel XMP 3.0 profiles they will be able to reach much higher frequencies. At first there was talk of speeds that would be around 6 GHz, but thanks to a new leak we have been able to discover that DDR5 memory support will reach some impressive 7,600MHz

This information has official validity, that is, it is not a simple rumor or speculation, since it has been extracted from profile data associated with the G.SKILL DDR5 memory for the ASUS Z790 ROG Maximus Hero motherboard. As we can see in the attached image, its XMP 3.0 profiles start at 7,200 MHz and peak at 7,600 MHz.

The list also cites different supported processors, the Core i7-13700K and Core i9-13900K, though only these last they could work with configurations at 7,466 MHz and 7,600 MHz, at least according to those listings. With respect to the latencies we see that these are very tightand it is that the 7,600 MHz DDR5 kits would remain at CL36, a very good figure if we take into account that the 6,000 MHz kits are around CL30 and CL36 latencies.

This confirms that Intel Raptor Lake-S processors will support faster memory kits than the Ryzen 7000since these reach their optimum point at 6,000 MHz. However, it is important to keep in mind that right now we can only find DDR5 kits at a maximum of 6,600 MHz on the market, and that we do not know the exact launch date of those kits at 7,200 MHz, 7,466 and 7,600 MHz. The price has not been revealed either, but it is clear that it will be high.

Secondly, Intel has also confirmed improvements to the Thread Director. of the Raptor Lake-S. This system is responsible for intelligently distributing the workload depending on the situation, and as we can see in the attached video, it fine-tunes the distribution between the P cores (high performance) and E cores (high efficiency) depending on the tasks that are in the foreground or background.
