Architecture Overview
The Meteor Lake-PS architecture represents Intel's transition to a disaggregated chiplet design for the desktop market. The Core Ultra 5 125HL utilizes a multi-tile approach where the compute tile is manufactured on Intel's 7nm process, while the SoC and I/O tiles are produced by TSMC on its N6 node, and the graphics tile leverages TSMC's N5 process. This heterogeneous integration allows Intel to optimize each functional block for its specific requirements. The processor employs a hybrid configuration with 'Redwood Cove' P-Cores for high-priority tasks and 'Crestmont' E-Cores for background workloads. Notably, it includes two LP E-Cores on the SoC tile designed for extremely low-power operation when the system is idle or performing basic tasks. The integration of an NPU (Neural Processing Unit) capable of 11 TOPS offloads continuous AI workloads from the CPU and GPU, improving overall system efficiency.
CPU Design
4 Redwood Cove P-Cores, 8 Crestmont E-Cores, and 2 Crestmont LP E-Cores.

History
The Core Ultra 5 125HL emerged from Intel's strategic shift toward tile-based architectures, originally debuting in the mobile sector as Meteor Lake before adapting to desktop platforms. Released on April 8, 2024, the Meteor Lake-PS series targeted edge computing and small form factor desktops rather than traditional high-performance gaming rigs. This launch marked a significant milestone for Intel, as it brought the Foveros 3D packaging technology to mainstream desktop processors.
The inclusion of an integrated NPU and Arc Xe-LPG graphics represented Intel's commitment to AI-ready computing. While the Core Ultra 5 125HL was not positioned as a flagship gaming CPU, it served as a foundational product for integrating AI-accelerated workloads into everyday desktop environments. The LGA 1851 socket introduction also provided a new platform foundation, though Meteor Lake-PS was largely seen as a transitional architecture bridging the gap to future generations with more robust desktop-specific optimizations.
