Intel Arrow Lake-S Nucleus with separate L3 cache, LGA 1851 platform will continue until 2026 according to sources

IT Home, August 20: Recent news reveals that the upcoming generation of Arrow Lake S-series processors will be called “Core Ultra”. This processor line is expected to be launched in late 2024 under the name Meteor Lake series as the successor of Core Ultra processors. The flagship of this processor line will be based on the LGA 1851 socket and feature an 8-core 16-core design. This corresponds to the current top model i9-13900K. A CPU boost of up to 21 percent compared to Raptor Lake is expected, as well as a doubling of the Core graphics unit’s performance thanks to the new architecture.

According to the TLC@leaf_hobby source, who communicated via Twitter or text messages, the core of the Intel Arrow Lake processor will have a standalone L3 cache. Likewise, it is reported that the Intel LGA 1851 platform will be available by 2026. This spans a three-year period, from 2024 to 2026, but it is unclear if Intel will launch three generations of LGA 1851 chipsets, as indicated by the source. In addition, the source also mentions that the Intel Arrow Lake processor might be different in some ways than expected. It is assumed that the processor, which will take the position of the i5-15600 (possibly called Ultra 5-160), will consist of 8 pure P cores and will not contain small cores.

Another informant, @miktdt, adds that the Arrow Lake processor was originally supposed to be based on Intel’s 20A process. However, it is now reported that it will come in a 6 P-core and 8 E-core model. The 8-core model, on the other hand, will be based on TSMC’s N3 process. There is speculation that the launch of the Intel 20A process may be delayed. According to @GoldenPigUpgradePack, the L2 cache will be increased to 3 MB per large core in the next-generation Arrow Lake S-series processors. This represents a 50% increase over Raptor Lake. The L2 cache of Arrow Lake-S will thus be equivalent to 2.4 times that of Golden Cove. The CPUs, on the other hand, will keep the same L3 cache as Raptor Lake.

According to rumors, the Intel Arrow Lake-S processor will be launched in conjunction with 800-series motherboards based on Lion Cove (P-Core) and Skymont (E-Core). The same architecture is also used by Lunar Lake, which is expected to target low power consumption platforms. Originally, Arrow Lake-S was supposed to be manufactured on the “Intel 20A” process, but recently rumors have surfaced that Intel has decided to outsource production to the TSMC N3 process.
