Intel Core Ultra 5 225H

The Intel Core Ultra 5 225H is a mobile high-end CPU for larger notebooks based on the Arrow Lake architecture. It offers 14 cores consisting of 4 fast performance cores (Lion Cove) with up to 4.9 GHz and 8 smaller efficiency cores (Skymont) with up to 4.3 GHz clock speed and two additional "low power" efficiency cores with up to 2.5 GHz (Skymont). The CPU has access to 24 MB of cache and is specified with a TDP of 28 watts (PL1, 115W PL2).

The SoC integrates a small dedicated NPU called AI Boost with 13 TOPS (Int8) and optionally supports vPro Essentials. The integrated memory controller supports up to 192 GB LPDDR5/x-8400 or DDR5-6400 (dual channel). The integrated GPU (iGPU) is an Intel Arc 130T graphics card which offers eight Xe cores with up to 2.2 GHz.

Performance - High End

Compared to the more powerful variants (such as the top model Core Ultra 9 285H) due to the lack of two P-cores. However, thanks to the improved IPC of the cores (especially the efficiency cores), the CPU should be able to hold its own against its Raptor Lake predecessors. As a result, the CPU is also very suitable for demanding tasks such as gaming and content creation.

Chiplet design

Like the desktop and HX chips, the Arrow Lake-H chips are based on individual chiplets that are placed on a 22nm base tile using Foveros 3D packaging. The CPU part comes from TSMC using the modern N3B (3nm) process. As with HX, the GPU also comes from TSMC and is manufactured using the N5P process. SoC and I/O Tile also from TSMC but in the older N6 process.
