Intel's 13th Gen Raptor Lake CPU Family - Hybrid Design Juiced Up!
So starting with the specifications, Intel's 13th Gen Raptor Lake CPUs will utilize the hybrid core design, featuring a mix of Performance-Optimized 'P' and Efficiency-Optimized 'E' cores. For the new chips, Intel will be using a brand new P-Core known as Raptor Cove which will replace the Golden Cove cores featured on the Alder Lake CPUs. For The E-Core, Intel will retain the existing Gracemont core architecture but it will come with minor improvements.
The architecture has seen several optimizations and key refinements that have led to an increase from 16 cores and 24 threads to 24 cores and 32 threads. The new 10nm ESF (Intel 7) process retains Intel's clock leadership, pushing the chips up to 5.8 GHz (up to 6 GHz on the KS variant).
Intel’s Raptor Lake will be built using the company’s new E and P cores, you can read the architectural deep dive over here, and represent a significant evolution in the company’s power efficiency targets. It will be built on the Intel 7 process and scale from 9 watts to 125 watts. DDR5 and PCIe gen5 will be supported (first to market) and feature new technologies like the Intel Thread Director.
Raptor Lake will be fully scalable from Desktop (LGA1700) to ultra-mobile. Interestingly, however, while the platform has 8 P-cores and 16 E-cores, only the P-cores will support hyperthreading making for a total of 32 threads available. The integrated GPU will have 96 EUs of Xe architecture (good but nothing to write home about) but the thing that impressed us the most was the fact that Intel is claiming a 20% IPC uplift over Rocketlake.
Raptor Lake will feature up to 35 MB of noninclusive LL Cache and support DDR5-5200, LP5-5600 DDR4-3200, and LP4x-4266. It will also support two times the PCIe bandwidth thanks to its support of PCIe 5 and will be able to provide up to 16 lanes of PCIe Gen5 with up to 64 GB/s. The new design is fully modular and built like lego and should be completely scalable and flexible. The compute fabric interconnect has a bandwidth of 1000 GB/s while the IO fabric has a BW of 64 GB/s. The memory subsystem supports up to 204 GB/s but more importantly can scale memory frequency (and power) according to the need of the SoC.
Intel Core i9-13900K 24 Core Raptor Lake CPU Specs
The Intel Core i9-13900K is the flagship Raptor Lake CPU, featuring 24 cores and 32 threads in an 8 P-Core and 16 E-Core configuration. The CPU is configured at a base clock of 3.0 GHz, a single-core boost clock of 5.8 GHz (1-2) cores, and an all-core boost clock of 5.5 GHz (all 8 P-Cores). The CPU features 68 MB of combined cache and a 125W PL1 rating that goes up to 253W. The CPU can also consume up to 350W of power when using the "Unlimited Power Mode" which we detailed here.

Intel Core i7-13700K 16 Core Raptor Lake CPU Specs
The Intel Core i7-13700K CPU will be the fastest 13th-Gen Core i7 chip on offer within the Raptor Lake CPU lineup. The chip features a total of 16 cores and 24 threads. This configuration is made possible with 8 P-Cores based on the Raptor Cove architecture and 8 E-Cores based on the Grace Mont core architecture. The CPU comes with 30 MB of L3 cache and 24 MB of L2 cache for a total combined 54 MB cache. The chip was running at a base clock of 3.4 GHz and a boost clock of 5.40 GHz. The all-core boost is rated at 5.3 GHz for the P-Cores while the E-Cores feature a base clock of 3.4 GHz and a boost clock of 4.3 GHz.
- Core i7-13700K 8+8 (16/24) - 3.4 / 5.3 GHz - 54 MB Cache, 125W (PL1) / 253W (PL2)
- Core i7-12700K 8+4 (12/20) - 3.6 / 5.0 GHz, 25 MB Cache, 125W (PL1) / 190W (PL2)
Intel Core i5-13600K 14 Core Raptor Lake CPU Specs
The Intel Core i5-13600K features a total of 14 cores which include 6 P-Cores based on the Raptor Cove and 8 E-Cores based on current Gracemont cores. That's the same P-Core count as the Intel Core i5-12600K but the E-Core count has been doubled. So we are looking at a 40% core count bump and a 25% thread count bump vs the Alder Lake Core i5-12600K. The CPU comes with 24 MB of L3 and 20 MB of L2 cache for a combined total of 44 MB cache. Clock speeds are set at 3.5 GHz base, 5.2 GHz boost, and 5.1 GHz all-core boost while the E-Cores operate at 3.5 GHz base & 3.9 GHz boost clocks.
- Core i5-13600K 6+8 (14/20) - 3.5 / 5.1 GHz - 44 MB Cache, 125W (PL1) /181W (PL2)
- Core i5-12600K 6+4 (10/16) - 3.6 / 4.9 GHz - 20 MB Cache, 125W (PL1) / 150W (PL2)
