Intel Core Ultra 5 Processor 125H

14C/18T · 4.5 GHz · 28 W

Entry model of the Core Ultra H-series, launched on December 14, 2023 with Intel's first Meteor Lake laptops. It was among the first Intel processors with a built-in NPU and uses a tiled design assembled with Foveros 3D packaging, with the CPU tile built on Intel 4 and the graphics tile made by TSMC. Its seven-Xe-core GPU carries the Arc branding when paired with dual-channel memory, and it was widely used in mainstream thin-and-light and creator laptops.

Notes: Intel's Arc graphics driver for this processor supports Windows 10 (21H2) and Windows 11, while the Intel NPU driver is available for Windows 11 only. Microsoft lists Core Ultra (Series 1) on the Windows 11 24H2 and 25H2 processor lists; 26H2's list is not yet published, so the 25H2 status is carried over. Linux runs from kernel 6.7 onward; the NPU uses the intel_vpu driver.
