CPU Intel: the “Core X” HEDT are back and there is already talk of Raptor Lake Core 13 to gen

18 November 2021 2

While the attention of insiders is directed to the Intel Core 12 to gen “Alder Lake-S” announced in at the beginning of November, the US company continues to work to bring the leadership of the consumer CPU market back to Santa Clara. Alder Lake has been positively received, but the manufacturer is already working on the next generation of desktop CPUs, let’s talk about the Core series 13 to gen “Raptor Lake” which, according to the latest rumors, is expected to debut on the market one year from now .

According to a recent tweet from the leaker momomo_US , Intel Raptor Lake (-S, we assume) will debut in the third quarter 2022, therefore in line with the autumn presentation of the Cores 12 in Jan of this year. But that’s not all, Intel would be preparing a return of the Intel Core X platform “High End Desktop” (O HEDT) with Sapphire Rapids-X processors code name Fishhawk .

Sapphire Rapids-X will resume Intel 7 production node from Alder Lake- S (10 nm SuperFin Enhanced) but it is not clear in which configurations core / thread i may arrive. Xeon versions of Intel Sapphire Rapids are credited with 56 core / 112 thread, but honestly it seems a bit too much for a solution that would be placed in the prosumer range; hold off 56 P-Core like those of Core i9 – 12900 K would not be feasible (even with halved frequencies), unless a large number of E-Cores are used (but here we are already going further with the assumptions).



The platform, which should be based on the W chipset 646, it will obviously support DDR5 memories (2021 MHz base a 8 channels assumed) and something like 36 PCI-E 5.0 lanes. Returning instead to the “mainstream” segment, Raptor Lake will see an update of the P-Cores with the new Raptor Cove probably flanked by efficient Gracemont cores revisited and in greater numbers. Below is an overview of what the Core line-up could be 13 a gen desktop (currently unofficial):

  • Intel Core i9 K (8 P-Core + 16 E-Core) = 24 Core / 32 Thread / 36 MB
  • Intel Core i7 K (8 P-Core + 8 E-Core) = 16 Core / 24 Thread / 30 MB
  • Intel Core i5 K (6 P-Core + 8 E-Core) = 14 Core / 20 Thread / 24 MB
  • Intel Core i5 S (6 P-Core + 4 E-Core) = 14 Core / 16 Thread / 21 MB
  • Intel Core i3 S ( 4 P-Core + 0 E-Core) = 4 Core / 8 Thread / 12 MB
  • Intel Pentium S (2 P-Core + 0 E-Core) = 2 Cores / 4 Threads / 6 MB

If these characteristics are confirmed (which is very likely), Raptor L ake-S should allow Intel to further boost multi-threaded performance, while ensuring that it takes advantage of the speed of Raptor Cove cores in gaming and other more demanding applications. U Further rumors on Raptor Lake concern consumption and in particular the support for the Digital Linear Voltage Regulator (DLVR) technology which, in a nutshell, consists in the integration of an additional voltage regulator connected in parallel to the primary regulator; this option applied to a motherboard would allow to reduce the energy consumption of the processor core, all without impacting on the complexity of the circuit and above all on costs.

The first data emerged on the web in recent days, show that the implementation of DLVR allows to decrease the VCORE of the CPU of approximately 160 mV , positively impacting on consumption since 20 to the 25% and allowing a performance increase in the order of 7% . Last note, unfortunately negative (if confirmed), always comes from momomo_US and concerns the socket; in fact, according to a tweet yesterday, it seems that Raptor Lake can use the new LGA socket 1800 which, in fact, would make the current (and excellent) LGA motherboards incompatible 1700 series 600.
