Core Ultra 9 285HX: CPU benchmarks and laptop guide

The Intel Core Ultra 9 285HX is a 2025 flagship from the Arrow Lake generation, a 24-core HX-class processor built for gaming laptops and mobile workstations. Eleven models in the catalog carry it, and it clears the recommended CPU requirement in 63 of the 69 games the catalog tracks. This guide covers where the chip sits among laptop CPUs, what it brings, and which laptops carry it.

Where the Core Ultra 9 285HX sits in 2026

A catalog score of 73.3 places the chip 71st of 741 scored laptop CPUs — comfortably inside the top ten percent. The neighborhood mixes mobile Ryzen parts: the Ryzen 5 6600H, Ryzen 5 PRO 6650H and Ryzen 7 7735U sit just above, the Ryzen 9 9955HX and Ryzen 7 PRO 6850U alongside, and the Ryzen 7 6800U just below. The catalog score rewards balanced laptop-class behavior, so raw desktop-replacement grunt is only part of the story here — the PassMark rating of 57,071 shows the untapped headroom.

What the chip brings

Arrow Lake-S brings 24 cores and 24 threads on a 3 nm-class process, running a 2.8 GHz base with up to 5.5 GHz boost. The 55 W HX rating means this silicon is meant for thick, well-cooled chassis rather than thin portables — it sustains clocks that lesser bins cannot. Memory support details were not captured for this chip, so the table above sticks to what the catalog verifiably holds, including that 57,071 PassMark overall score.

Games: CPU-side readiness

Measured purely as a processor, the chip clears the recommended CPU tier for 63 of 69 cataloged games — Cyberpunk 2077, Fortnite, The Witcher 3, Red Dead Redemption 2, Alan Wake 2, Resident Evil 4 Remake, Forza Horizon 5 and Counter-Strike 2 among them. Six demanding titles sit at the minimum tier only: Starfield, Helldivers 2, Call of Duty: Warzone, Baldur's Gate 3, Hogwarts Legacy and Elden Ring all ask for more CPU than the recommended settings specify. These verdicts are CPU-only — actual playability depends on the laptop's GPU and RAM, though most 285HX machines pair it with top-tier discrete graphics.

Laptops that carry it

The 11-model roster splits between big gaming rigs and workstations: MSI's Titan 18 HX AI, Raider 18 HX AI, Vector 16 HX AI and Vector 17 HX AI (all 2025, $1,440), Dell's Pro Max 16 Plus and 18 Plus, plus HP ZBook Fury G1i 16-inch and 18-inch at $1,760 and Dell Precision 7690 and ZBook Fury 16 G11 at $1,408. Lenovo's ThinkPad T16g Gen 3 covers the business side at $1,144. Roster medians describe the fleet honestly: gaming index 88, engineering and modeling indices at 94, photo design 91, office comfort a perfect 100 — but a portability index of 12.5 and mobility of 29, because these are heavy desktop replacements.

Bottom line

The Core Ultra 9 285HX suits buyers who want maximum sustained CPU power in a laptop and accept the weight that comes with it. For gaming, the processor clears the recommended tier for nearly the entire catalog, so the GPU on the specific laptop becomes the deciding factor. For engineering, modeling and rendering work, the roster around it — ZBook Fury, Precision, MSI HX — is built exactly for that. What it is not: a travel machine, with portability medians in the low teens.
