We’ve extensively covered Intel’s 15th Gen Arrow Lake processors in the past. They will be the first “true” next-generation chips for gamers from Team Blue since the release of Alder Lake. An advanced process node and upgraded core architectures should offer a 15% performance uplift at the same or lower power consumption. The P-cores will be upgraded to Lion Cove and the E-cores to Skymont on the 20A process node.
The above holds for the Arrow Lake-S desktop processors, but the 28W U-series lineup will be a Meteor Lake node shrink to the Intel 3 (3nm) process node. Bionic_Squash (X) claims that “Arrow Lake-U is a cheaper alternative to Lunar Lake.” It’ll leverage the same core architecture (Redwood Cove/Crestmont) as Meteor Lake, optimized for the refined Intel 3 node. You can expect a 10% performance-per-watt improvement in multi-threaded workloads.
Lunar Lake will feature the same core design as Arrow Lake but will be fabbed on TSMC’s 3nm node (N3B). It is designed as a mobile-first SoC for always-on notebooks and convertibles. Like most such devices (Microsoft Surface, LG Gram, Lenovo Yoga), the prices will likely be over the top. To make the low-power segment more accessible, Intel is readying a Meteor Lake node shrink on the 3nm process.
