Core i3-4000M: CPU benchmarks and laptop guide

The Intel Core i3-4000M was the entry-level Haswell of 2013 — a hyper-threaded dual-core for mainstream laptops — and five catalog machines carry it, all ThinkPads from the same year. Against the modern catalog it meets the recommended CPU tier in 0 of the 69 tracked games, though a set of lighter titles does clear the minimum bar. This guide covers its ranking, its specifications, and the laptops built around it.

Where the Core i3-4000M sits in 2026

A catalog score of 22.8 places the chip 435th of 741 scored laptop CPUs — the lower half of the table. The neighborhood straddles eras: the Core i7-7500U (23.4), Core i5-7300U (23.3) and Core i5-3350P (23) just above, and the Pentium G4560 (22.6), Athlon Silver 3050U (22.6) and Core i5-4210U (22.4) just below. Sitting level with Kaby Lake low-power chips is decent longevity for entry-level 2013 silicon — but entry-level is the operative phrase, and it stays that way in 2026.

What the chip brings

Haswell gives the chip two cores and four threads on a 22 nm process with a 37 W rating, running at a flat 2.4 GHz with no boost clock — the i3 line did without turbo then. Public benchmarks read 722 single-core and 1,446 multi-core in Geekbench. Four threads keep basic multitasking alive, but the dual-core foundation is what caps this chip against everything the modern catalog asks of a processor.

Games: CPU-side readiness

As a processor, the chip meets the recommended CPU tier for 0 of 69 cataloged games — but it is not below every bar. A group of lighter titles clears the minimum tier: Minecraft, Valorant, Dota 2, League of Legends, Sims 4, Diablo 4, F1 24, Doom Eternal, Star Wars Jedi Fallen Order, Hitman 3, God of War and Horizon Zero Dawn all list it above minimum but below recommended. Everything heavier — Cyberpunk 2077, Elden Ring, Fortnite, Baldur's Gate 3 and up — is out of reach. These verdicts are CPU-only; actual playability depends on the laptop's GPU and RAM, and this era of ThinkPad was rarely configured with strong graphics.

Laptops that carry it

The roster is five 2013 ThinkPads: the L540 at $137, T540p at $147, L440 at $174, T440p at $145 and E540 at $132. The laptops built around it typically show a median best CPU score of 41.7 and best GPU score of 45.9, with a performance index of 39.1. Median office comfort sits at just 30, energy efficiency at 49.3 and mobility at 15 — these were heavy, no-frills work machines, and the metrics say so plainly.

Bottom line

The Core i3-4000M is honest budget territory in 2026: enough processor for browsing, documents and lightweight games at minimum settings, inside durable ThinkPad chassis that cost $132–$174 today. It suits a student spares-pool machine or a cheap office workhorse, provided expectations stay at the basics. For anything approaching modern gaming or sustained heavy work, step up the catalog — even the neighboring i5-class chips buy meaningfully more capability.
