Core Ultra 7 255U: CPU benchmarks and laptop guide

The Intel Core Ultra 7 255U is an Arrow Lake-U processor from the second Core Ultra generation, launched in 2025, and the catalog matches it to 29 models. It is a 12-core, 15-watt efficiency design for thin business laptops, and measured purely as a processor it meets the recommended CPU requirement in 36 of the 69 games the catalog tracks. This guide covers where the chip sits among laptop CPUs, what it brings to a portable, and which laptops carry it.

Where the Core Ultra 7 255U sits in 2026

A catalog score of 52.3 places the chip 245th of 672 scored laptop CPUs — the middle of the table. The neighborhood mixes generations: the Ryzen AI 7 445 (52.6), Core Ultra 5 228V (52.6) and Core i7-8705G (52.3) just above, the Core i5-8279U (52.2), Core Ultra 5 225U (52.1) and Core Ultra 5 235U (51.9) just below. A 2025 chip ranking level with older Core i7 and Core i5 parts — and with its own Ultra 5 siblings — reflects what the table measures: raw processor throughput. The chip's case rests elsewhere, on delivering that throughput inside a 15 W envelope on a 5 nm process.

What the chip brings

Arrow Lake-U gives the chip 12 cores and 14 threads on a 5 nm process, with a 3.8 GHz base clock boosting to 5.2 GHz inside a 15 W U-class rating. The integrated GPU is a 4-core Intel design shared across the Meteor and Arrow Lake generations, clocked up to 2,100 MHz. Memory support details were not captured for this chip. Of the public benchmarks, the catalog holds a PassMark overall score of 17,902.

Games: CPU-side readiness

Measured purely as a processor, the chip clears the recommended CPU tier for 36 of 69 cataloged games — Dying Light 2, Far Cry 5, Diablo 4, Flight Simulator 2020, Escape from Tarkov, Doom Eternal and God of War among them. A further 26 sit at the minimum CPU tier: Hogwarts Legacy, Cyberpunk 2077, The Witcher 3: Wild Hunt, Counter-Strike 2, Black Myth Wukong and Metro Exodus all list the chip above their minimum but below their recommended CPU requirement. Seven fall below minimum entirely: Starfield, Helldivers 2, Call of Duty: Warzone, Baldur's Gate 3, Elden Ring, Apex Legends and Fortnite. These verdicts are CPU-only — actual playability depends on the laptop's GPU and RAM, and this fleet's graphics are almost entirely integrated.

Laptops that carry it

The 29-model roster is uniformly fresh — every displayed laptop is a 2025 machine, and Lenovo dominates. The ThinkPad T14 Gen 6, L14 Gen 6, X13 Gen 6 and X1 2-in-1 Gen 10 Aura Edition all sit at $1,144, with the T16 Gen 4 at $1,284; Samsung's Galaxy Book 5 is $1,232, Acer's TravelMate P4 Spin 14 and Lenovo's IdeaPad 5i 2-in-1 convertibles $1,275, and the Dell 15 is the value entry at $765. Roster medians describe the fleet honestly: office comfort at a perfect 100, energy efficiency 93.2 and mobility 81 — but a gaming index of 19 and a median best-GPU score of zero, because these are integrated-graphics machines.

Bottom line

The Core Ultra 7 255U is the pick for a brand-new, quiet, all-day business laptop: office comfort is flawless and the CPU clears the recommended tier for just over half the tracked games. It is not a gaming machine's processor — the fleet's graphics say as much. The catalog's compare pages against the Core Ultra 7 255H, Core Ultra 7 258V and Core Ultra 9 185H map the modern alternatives.
