Intel Arrow Lake-S Desktop CPU Platform Leaks Out: 24 CPU Cores, DDR5-6400, 800-Series Motherboard Support

Details of Intel's next-gen Arrow Lake-S desktop CPU platform have been leaked and pointed out up to 24 cores on the 800-series motherboards.

Intel Arrow Lake-S Platform Leak: CPUs With Up To 24 Cores, 8 IA Cores, 800-Series Motherboards, Faster DDR5 Support

The latest platform leak comes from YuuKi_AnS who has published internal documents of the upcoming Arrow Lake-S Desktop CPU platform. While we know a lot about the Intel Arrow Lake CPUs already, it looks like we have a better look at what the platform is going to offer.

Starting with the CPUs, the Intel Arrow Lake-S Desktop CPUs will feature the Lion Cove P-Core and Skymont E-Core architecture. These chips will feature up to 8 P-Cores and 16 E-Cores for a total of 24 cores and 32 threads so similar to the existing 14th and 13th Gen flagship CPUs. The chips will come in up to 125W PL1 TDPs and feature a 3.5 GHz base clock at max (Pre-Alpha state). The CPUs will also get the latest GT1 Xe-LPG iGPU but with reduced Xe-cores compared to the ones featured on Meteor Lake CPUs. Interestingly, Intel separately mentions 8 IA cores with 8 threads and they are mentioned to be disabled in the 125W variant.

According to a previously leaked slide, the Intel Arrow Lake-S Desktop CPUs offer a 5% IPC increase and a 15% increase in multi-threaded performance. There's also mention of the new P-Cores & E-Cores which we already know are based upon the Lion Cove and Skymont architectures. The CPUs will also feature up to 50% larger L2 cache as we reported earlier.

• Arrow Lake-S (Lion Cove P-Core) - 3 MB L2 Cache Per Core
• Raptor Lake-S (Raptor Cove P-Core) - 2 MB L2 Cache Per Core
• Alder Lake-S (Golden Cove P-Core) - 1.25 MB L2 Cache Per Core

The slide mentions the family as the 15th Gen lineup so either it could be old or the company still uses the older branding for the desktop family. The Intel laptop CPUs have shifted
