Hardware leaker YuuKi_AnS has leaked a document revealing pre-Alpha specifications for the Intel Arrow Lake platform. More specifically, while CPU specifications such as clock speeds may change, the platform design is almost certain to remain unaltered.
Arrow Lake-S Platform Detailed:
The successor to Raptor Lake on desktop is said to arrive in the second half of this year. Codenamed ‘ Arrow Lake ‘, Intel aims to give Zen5 a run for its money but that is yet to be seen.
Going over the details, Arrow Lake-S (S=Desktop) processors will feature a maximum of 24 total cores. The 24 cores are divided into 8 Performance (Lion Cove) and 16 Efficient cores (Skymont). There is also a mention of 8 IA Cores / 8 Threads, but these will remain disabled in 125W chips.

Arrow Lake on desktop will use GT1 Xe-LPG -based graphics, a large leap from Raptor Lake . Quite notably, the specified pre-Alpha CPU here can boost up to 3.5GHz at best. While concerning, silicon quality is expected to improve so take this number with a grain of salt.
Intel’s Arrow Lake CPUs will use a new socket, LGA 1851 , meaning you will have to purchase a new 800-series motherboard. The document reveals that LGA 1851 packs 24 Total PCIe lanes, 20 based on Gen5 (1×16 + 1×4) and 4 based on PCIe Gen 4 .

Next up, we also have a block diagram of 2 Arrow Lake-S configurations, one with 22 cores and the other with 14 cores. Now this does seem intimidating, but a few key highlights of the diagram are as follows.
Arrow Lake will feature support for dual-channel DDR5-6400 memory (JEDEC). The figure hints that CPUs below 14 cores may be limited in terms of I/O and connectivity since these specs are only applicable to the 6P+8E configuration and higher.
