Another Intel 13th Gen Raptor Lake Core i9-13900K CPU has been spotted within the Intel GFX CI, offering up to 32 threads.

The latest entry comes from within Intel's own Bootlog and this chip is once again, supposedly, the flagship configuration that you will find on the 13th Gen Raptor Lake-S Desktop CPUs that are due for launch later this year. While we have already seen a similar sample leak out earlier, the latest entry has been discovered by Coelacanth-dream.

The supposed Intel Core i9-13900K Raptor Lake-S Desktop CPU features 32 threads and we know from previous information that this chip would also rock 24 cores of which 8 will remain as P-cores but the E-core count would be doubled to 16. Overall, this would mark a 50% improvement in cores and a 33% improvement in thread count. The chip was running on the RPL-S ADP-S DDR5 UDIMM CRB reference platform which makes use of DDR5 memory and the highest clock achieved is 1800 MHz or 1.8 GHz.

This is expected of an early engineering sample since we have seen initial Alder Lake CPUs running around the same frequency but ended up offering higher than 5 GHz clocks (A 5.5 GHz Core i9-12900KS is also in the works). The specific entries in the Intel GFX CI are mentioned below (Credits: Coelacanth-dream)

Other details show that Intel's 13th Gen Raptor Lake-S CPUs will come without AVX-512 support. It is something that Intel has also started disabling for current 12th Gen Alder Lake-S CPUs by making motherboard makers release a new BIOS. Other than that, we know that the first 13th Gen Raptor Lake enablement patches are headed to Linux soon.

Replacing the Intel Alder Lake-S 12th Gen Core family, the Intel  Raptor Lake-S lineup will be part of the 13th Gen Core family and feature two brand new core architectures. These architectures will be featuring Raptor Cove as performance cores & an enhanced Gracemont core which will be serving as efficiency cores.

Intel Raptor Lake-S Desktop CPU Lineup & Configurations

According to previously leaked data, the lineup will consist of three segments that were leaked out in the recent power recommendations. These include the 'K' series enthusiast SKUs rated at 125W, 65W mainstream SKUs, and 35W low-power SKUs. Coming to the top-end variants, we will be getting up to 24 cores followed by 16 core, 10 core, 4 core, and 2 core variants. The SKUs are detailed below:

The enthusiast 125W Intel Raptor Lake-S Desktop SKUs will feature Core i9 models featuring up to 8 Raptor Cove cores and 16 Gracemont cores for a total of 24 cores and 32 threads. Intel's Core i7 lineup will consist of 16 core (8+8), Core i5 models will consist of 14 core (6+8) and 10 core (6+4) & finally, we have the Core i3 models which will feature 4 cores but without any efficiency cores. The lineup will also include Pentium SKUs which will feature just 2 Raptor Cove cores. All Core variants will feature a 32 EU (256 core) enhanced Xe integrated GPU. Certain Core i5 and Pentium variants will also come configured with 24 EU and 16 EU iGPUs.

Intel Raptor Lake-S Desktop CPU Platform Details

Other details include a larger L2 cache which will be branded as Intel's own 'Game Cache' for Core CPUs and clock speeds will feature a boost clock bump of 200 MHz so we can expect up to 5.5 GHz boost clocks considering Alder Lake-S Desktop CPUs will top out at 5.3 GHz.

The Intel Raptor Lake-S chips will also support faster DDR5 memory speeds of up to 5600 Mbps (6500 Mbps LPDDR5(X)) along with retaining support for DDR4 memory as reports suggest. It looks like there will be three main dies which will be configured into these SKUs starting with a top 'Large' die consisting of 8 Cove and 16 Atom cores, a 'Mid' die with 8 Core and 8 Atom cores, and lastly, a 'Small' die with 6 Cove cores and no Atom cores. The Intel Raptor Lake lineup will be compatible with the LGA 1700 socket though will utilize all 1800 contact pads and compete against AMD's Zen 4 powered Ryzen 7000 lineup. Expect more info by the mid of 2022 by Intel.
