Core i3-4100M: CPU benchmarks and laptop guide

The Intel Core i3-4100M is the slightly faster sibling of Haswell's entry-level mobile line — a hyper-threaded dual-core from 2013 at 2.5 GHz — and five catalog laptops carry it, all ThinkPads of the same vintage. Measured against the modern catalog it meets the recommended CPU tier in 0 of the 69 tracked games, though a band of lighter titles clears the minimum. This guide covers its position, its specs and its carrier laptops.

Where the Core i3-4100M sits in 2026

A catalog score of 25.3 places the chip 415th of 741 scored laptop CPUs — the lower half of a very long table. The bracket is a mix of old and newer budget parts: the Pentium G4620 (25.9), Core i5-5300U (25.7) and Ryzen 3 3200U (25.6) just above, the Core i3-7100U (25) and Core i5-4310U (25) level below them, and the Core i7-4500U (24.8) rounding out the group. Trading places with chips released up to six years later is respectable for entry silicon — but the absolute capability remains modest.

What the chip brings

Haswell delivers two cores and four threads on a 22 nm process with a 37 W rating, running at a flat 2.5 GHz — no turbo, just a fixed modest clock. Public benchmarks read 766 single-core and 1,554 multi-core in Geekbench. Four threads give it a little breathing room for everyday multitasking, which was the point of hyper-threading on entry parts; everything else about the design is plain 2013 mainstream hardware.

Games: CPU-side readiness

On processor muscle alone the chip meets the recommended CPU tier for 0 of 69 cataloged games. It does clear the minimum tier for a meaningful band of titles: Minecraft, Valorant, Dota 2, League of Legends, Sims 4, Diablo 4, F1 24, Doom Eternal, Death Stranding, Borderlands 3, Gears Tactics, Star Wars Jedi Fallen Order, God of War and Horizon Zero Dawn among them. Everything heavier — Cyberpunk 2077, Elden Ring, Fortnite, Baldur's Gate 3 and above — is beyond it. These verdicts are CPU-only: actual playability depends on the laptop's GPU and RAM, and the ThinkPads in this roster rarely carried graphics to match even the lighter titles well.

Laptops that carry it

All five carriers are 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, office comfort of 30, energy efficiency of 49.3 and mobility of 15. The picture is consistent: chunky, durable business bodies with the kind of internals a 2013 office budget bought.

Bottom line

The Core i3-4100M is a fixed-clock workhorse for the used-market minimum: browsing, office documents and lighter games at minimum settings, inside $132–$174 ThinkPad chassis that refuse to die. It fits buyers who need a cheap secondary machine or a platform for undemanding work. The step from here to a quad-core of the same era costs little more on the used market and opens far more of the catalog — worth taking if the budget allows.
