Core i5-1245U: CPU benchmarks and laptop guide

The Intel Core i5-1245U was the volume 12th-gen Alder Lake engine of thin business laptops — a 10-core design from 2022 built for quiet, cool machines that last a workday. The catalog matches it to 26 models, and it meets the recommended CPU requirement in 17 of the 69 games the site 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 i5-1245U sits in 2026

A catalog score of 46.2 places the chip 291st of 672 scored laptop CPUs — the middle of a table that spans two decades of silicon. The neighborhood mixes eras and badges: the Core i5-1334U (46.6), Core i7-1255U (46.3) and Core i5-10210U (46.2) just above, and the Core 3 100U (46), Core i7-4810MQ (45.8) and Core i7-7567U (45.6) just below. Sitting within half a point of the i7-1255U two places up — and still outranking i7-branded parts below it on a 15-watt budget — is the practical story: in this window the i5 badge gives up almost nothing to its i7 sibling.

What the chip brings

Alder Lake-U is a 10-core, 12-thread design on a 7 nm-class process, rated at 15 W in its U-class configuration: a 1.6 GHz base and up to 4.4 GHz boost. Memory support is broad for the class — DDR5-4800, DDR4-3200, LPDDR5-5200 and LPDDR4x-4267 over two channels, up to 64 GB — and the integrated Iris Xe graphics carry 80 execution units. In public benchmarks the chip posts a PassMark overall score of 12,770; Geekbench results were not captured.

Games: CPU-side readiness

Measured purely as a processor, the chip clears the recommended CPU tier for 17 of 69 cataloged games — older and mid-weight titles like God of War, Horizon Zero Dawn, Control, Forza Horizon 4, Grand Theft Auto V and Civilization 6. Another 37 sit at the minimum tier: Cyberpunk 2077, The Witcher 3, Red Dead Redemption 2, Hogwarts Legacy and Alan Wake 2 all list the chip above their minimum but below their recommended CPU requirement. The remaining 15 — Starfield, Helldivers 2, Baldur's Gate 3, Elden Ring, Fortnite, Counter-Strike 2 and Black Myth Wukong among them — ask for more processor than this. These verdicts are CPU-only — whether a game actually plays well depends on the laptop's GPU and RAM, and this chip's machines lean on integrated graphics.

Laptops that carry it

The 26-model roster is a 2022–2023 corporate fleet: Dell Latitude 5330 through 7530 between $403 and $475, the Latitude 7330 Ultralight at $886, and the HP side running from EliteBook 640 G9 and 840 G9 at $410–$415 through the EliteBook 650 G9 at $476 to the EliteBook 1040 G9 at $536, with the Precision 3570 workstation alongside at $536. Roster medians describe the fleet honestly: office comfort at 95, energy efficiency 86.8 and mobility at 79 are the strengths, while a gaming index of 28 reflects an integrated-graphics fleet rather than anything about the processor itself.

Bottom line

The Core i5-1245U suits a buyer who wants an efficient, modern office portable at used prices in the $400–$560 range — quiet and comfortable for full workdays, with enough processor for lighter and older games at their recommended CPU settings. It is not a gaming engine: most of the tracked catalog sits below its recommended tier, and the 80-unit Iris Xe rules out anything demanding. Judge each listing by its GPU and RAM; for work-first use, the processor will rarely be the reason to say no.
