Overview
Fabricated on Intel’s Arrow Lake Refresh microarchitecture, the silicon layout expands core density to a 24-core topology pairing 8 Performance cores with 16 Efficient cores on the LGA 1851 socket. Clock dynamics operate from a 3.7 GHz base up to a 5.4 GHz boost on the Performance cores, while the Efficient cluster scales from a 3.2 GHz base to a 4.7 GHz boost. Memory and expansion routing support high-capacity DDR5 configurations up to 256 GB alongside native PCIe 5.0 and PCIe 4.0 bus lanes, backed by a generous on-die cache structure comprising 40 MB of L2 and 36 MB of L3 cache.
From an integration standpoint, the processor adheres strictly to the LGA 1851 land grid array interface, mating directly with Intel 800-series chipsets via an integrated heat spreader designed for uniform planar pressure. Operating with a 125 W processor base power rating, system builders must pair the chip with an adequate thermal solution to manage heat flux across the multi-tile package during sustained compute bursts. Crucially, the microarchitecture eschews simultaneous multithreading, dedicating exactly 24 hardware threads across its 24 physical cores. This architectural shift prioritizes deterministic thread scheduling and instruction pipeline throughput, delivering stable multi-threaded execution for production workstations and high-refresh gaming rigs while maintaining predictable firmware voltage tables across 800-series motherboards.
