Core i5-4300U: CPU benchmarks and laptop guide

The Intel Core i5-4300U is a 2013 Haswell dual-core that brought 15 W efficiency to the business ultrabooks of the mid-2010s, and 14 matched models in the catalog carry it. As a processor it meets the recommended CPU tier in 0 of the 69 games the site tracks. This guide covers where the chip sits among laptop CPUs in 2026, what it brings, and which laptops still run it.

Where the Core i5-4300U sits in 2026

A catalog score of 23.6 places it 430th of 741 scored laptop CPUs — the budget/legacy band. The neighborhood is instructive: the Core i5-5200U (23.9), Core i7-7600U (23.8) and Ryzen 3 3250U (23.7) sit just above, with the Core i3-7020U (23.6), Core i7-7500U (23.4) and Core i5-7300U (23.3) just below. A 2013 15 W i5 landing level with Kaby Lake i7s from 2017 says less about Haswell's brilliance and more about how little ultrabook performance moved in those years — a plateau Intel only broke with more cores later on.

What the chip brings

Haswell-U here is a 2-core, 4-thread design on the 22 nm process, rated at 15 W: a 1.9 GHz base clock with Turbo Boost to 2.9 GHz. Graphics come from the integrated Intel HD Graphics 4400 — adequate for the desktop workloads these machines were sold for, nothing beyond. Public benchmark data shows a Geekbench single-core score of 790 with 1,471 multi-core and a PassMark overall score of 2,487, consistent with its low-power positioning.

Games: CPU-side readiness

Measured purely as a processor, the chip clears the recommended CPU tier for 0 of 69 cataloged games. It does hold above the minimum bar for a long tail of lighter and older titles — Minecraft, Valorant, Dota 2, League of Legends, Sims 4, Doom Eternal, God of War and GTA V among them — while heavier games such as The Witcher 3, Overwatch, Fortnite, PUBG and Cyberpunk 2077 all fall below minimum. These verdicts are CPU-only: actual playability depends on the laptop's GPU and RAM, and the roster is built almost entirely around integrated graphics.

Laptops that carry it

The 14-model roster is classic 2013–2015 corporate hardware: ThinkPads in the T440, T440s, T540p and L450, Dell Latitudes in the E5440, E5540, E7240 and E7440, and HP EliteBooks in the 820 G1, 840 G1, 850 G1 and Folio 1040 G1. Every model is business-class, priced from $120 for an EliteBook 840 G1 to $227 for the Latitude E5540. Laptops built around it typically show a median portability index of 62.6, energy efficiency of 54.7 and office comfort score of 30 — light commuters for their day, modest performers now.

Bottom line

The i5-4300U is a chip for the used-market buyer who wants a cheap, genuinely portable business machine for office work and browsing — the $120–$230 ThinkPad, Latitude and EliteBook tier delivers exactly that. Gaming ambitions should be capped at old or light titles: 0 of 69 games at recommended CPU tier is the whole story. It matches i7s from four years later on paper, but only because that era stood still — anything from the eight-core generation onward is a different league.
