Lunar Lake an Intel Mobile Processor: SoC Architecture Overview (2024)

Lunar Lake (LNL) is the codename for Core Ultra Series mobile processors designed by Intel, released in September 2024. LNL took ambitious targets to cope with core and graphics performance, performance/watt, battery life, and AI compute for an outstanding user experience. To address that, a ground up architecture was defined. LNL enhanced the partition of cores to performance and efficient clusters with the ability to contain SW load to the desired HW at runtime, it optimized performance cluster with single threaded core, revised the idle state management, reduced frequent CPU wakes, enhanced the memory sub system power states and added fine grain power delivery. LNL added premium capabilities such as Memory-On-Package (MOP), Power Management IC (PMIC), powerful Neural Processing Unit (NPU), memory side cache, and Total Storage Encryption (TSE) for NVMe. LNL architecture scales from 8W to 30W+ and supports LPDDR5 frequencies up to 8533Mhz.
