Intel Core Ultra 7 255H

The Core Ultra 7 255H is the main Core Ultra 7 model in Intel's 200H family, the Arrow Lake based successor to the Core Ultra 7 155H. It has 16 cores split into 6 performance cores, 8 efficient cores and 2 low-power efficient cores, with 16 threads in total. Performance cores run from 2.0 GHz up to 5.1 GHz and share 24 MB of Intel Smart Cache. It supports LPDDR5X-8400 or DDR5-6400 memory in two channels, up to 128 GB, plus Thunderbolt 4 and up to 28 PCIe lanes including PCIe 5.0.

Six performance cores make the 255H a strong all-rounder. Office work and browsing feel instant, and it has the headroom for video editing, 3D work, code compiles and gaming with a dedicated GPU. The 28 W base power and 115 W maximum turbo power let makers tune it for a quiet thin laptop or a thicker machine that holds high clocks for longer, so the same chip can perform quite differently from one laptop to the next.

The integrated Intel Arc 140T GPU has 8 Xe-cores running at up to 2.25 GHz. It is one of the stronger integrated GPUs in Intel's lineup, good for 4K video, multiple displays, creative apps and many games at low to medium settings when paired with fast dual-channel memory. The NPU is rated at 13 TOPS, and Intel lists 96 TOPS for the chip as a whole. That covers Windows Studio Effects and local AI tools, but not Copilot+ PC features, which need a 40+ TOPS NPU.

Against the Core Ultra 7 155H it replaces, the 255H keeps 16 cores, drops Hyper-Threading and uses newer cores with a higher boost clock. AMD's Ryzen AI 7 350 is the direct rival, with 8 cores, 16 threads and a Copilot+ class NPU, and the Ryzen 7 8845HS is a common 8-core alternative in similar laptops. The Core Ultra 7 265H is a slightly faster sibling with vPro, and the Core Ultra 9 285H sits at the top of the family. The comparison pages below show each spec side by side.

Yes, for most people who want a fast laptop for work, creative apps or gaming with a dedicated GPU. It is often the value pick in the 200H range, since the 265H mainly adds higher clocks and vPro business features. Pick a model with good cooling and 16 GB or more of dual-channel memory. If you need Copilot+ features or the longest battery life, look at Ryzen AI 300 or Core Ultra 200V laptops.
