Arrow Lake-S has a higher priority than the mobile version, and Intel may cancel Arrow Lake-U

Intel is expected to release Meteor Lake, Arrow Lake, and Lunar Lake after Raptor Lake. Arrow Lake is the 15th generation Core processor, and Arrow Lake-S, which is a desktop platform, uses the next-generation LGA 1851 socket, just like Meteor Lake-S.

According to Moore’s Law Is Dead, Intel is expected to release Arrow Lake in the second half of 2024. Surprisingly, Intel has prioritized Arrow Lake-S for desktop platforms and has placed it ahead of the corresponding mobile version. There are rumors that Intel may cancel Arrow Lake-U due to the sufficient supply of Meteor Lake and the more targeted design of Lunar Lake.

It has been reported previously that Lunar Lake uses a new CPU architecture and underlying design, primarily focused on improving performance per watt for mobile devices. It is expected to tape out in 2024 and be ready for production. Its initial design targets the 15W low-power mobile processor submarket, aiming to create ultra-thin and lightweight systems, just like Arrow Lake-U.

As previously stated, the highest configuration of Arrow Lake-S is identical to the existing Raptor Lake-S, with 8 P-Cores and 16 E-Cores, totaling 24 cores and 32 threads. The P-Core using the Lion Cove architecture is the main source of performance improvement for Arrow Lake, with an IPC increase of 20% compared to the Redwood Cove architecture of Meteor Lake and a 45% increase compared to the Golden Cove architecture of Alder Lake.

Moore’s Law Is Dead indicates that the computing module of Arrow Lake-S will be manufactured using TSMC’s 3nm process, while the mobile version will use Intel’s 20A process. This means that the desktop version will be almost entirely manufactured by TSMC. Intel hopes that the Lion Cove architecture-based P-Core will have better performance, with an IPC increase of 22% to 34% compared to the Redwood Cove architecture-based P-Core.
