With new high-performance P-cores and high-efficiency E-cores coupled to complete diversified structure creation, the Intel Alder Lake processor family ushered in a wave of hybrid designs that swept the client market. The next-generation Intel Raptor Lake CPUs will continue to be supported in the future Linux kernel, according to Phoronix.

The application ecosystem is presently preparing for Intel’s unique Raptor Lake design, which is anticipated to arrive in the fourth quarter of this year. Audio support for the new Intel Raptor Lake processors has recently been added to the Linux kernel 5.18.

Raptor Lake processors will include a next-generation Raptor Cove core arrangement with up to 24 cores and 32 threads. The highest SKU for the 13th generation Intel CPUs will have 8 Raptor Cove and 16 Gracemont Enhanced cores, accessing a total of 32 threads. The new Intel family will have a total of 54 MB of Smart Cache, with 36 MB of L3 cache for all bodies and 18 MB of L2 cache for the premium Raptor Core chipset.


Each Raptor Cove core is expected to have 2 MB L2 / 3 MB L3 cache, while each Gracemont Cluster will have 4 MB L2 and 3 MB L3 cache, for a total of 36 MB L3 cache across all cores, 16 MB (2×8) P-cores, and 16 MB (4×4) E-cores. The 125W Intel Raptor Lake-S model will have PL1 ratings of 125W, 188W, and 238W, respectively. Raptor Lake is said to provide anywhere from 125W to 314W in performance settings.

According to the source, Raptor Lake enabling is a process that has been ongoing since Skylake was first noticed, in which adding new IDs to the drivers improves the end product. Regardless, Intel’s decision to take their time prepping Raptor Lake’s software enablement across the board to ensure the product’s functionality is noteworthy. Intel’s Raptor Lake-S Gen 12-based graphics card received initial software assistance in Linux kernel 5.17. Once the software packages are fully mature, support for Raptor Lake will be fully available when the new processors arrive at the end of this year.
