Core i3-1005G1: CPU benchmarks and laptop guide

The Intel Core i3-1005G1 is an Ice Lake processor from 2019 that powered affordable student and home laptops, and 17 catalog models carry it. Against the 69 games the catalog tracks it meets the recommended CPU requirement in just 7 of them. This guide covers where the chip ranks among laptop CPUs, what two cores at 15 W mean in practice, and which cheap machines still carry it.

Where the Core i3-1005G1 sits in 2026

A catalog score of 41.2 places the chip 354th of 737 scored laptop CPUs — the middle of the table, leaning down. The neighborhood is classic budget territory: the Core i7-8650U (41.6), Ryzen 3 2300U (41.4) and Core i5-7267U (41.2) just above, and the Core i7-6567U (41), Core i7-8550U (40.8) and Pentium 6805 (40.7) below. An entry i3 holding rank with U-series i7s of neighboring generations is the familiar budget-chip story — near-parity throughput a tier below the badge.

What the chip brings

Ice Lake gives it 2 cores and 4 threads on a 10 nm process at a 15 W U-series rating: a 1.2 GHz base with boosts to 3.4 GHz. Public benchmarks record a GeekBench single-core score of 1,286, a multi-core of 2,388, and an overall PassMark of 4,795 — entry-level figures by any modern measure. Two cores handle one or two applications comfortably and run out of headroom quickly beyond that.

Games: CPU-side readiness

Measured purely as a processor, the chip clears the recommended CPU tier for only 7 of 69 cataloged games: Grand Theft Auto V, Overwatch, Civilization 6, Rainbow Six Siege, Rise of the Tomb Raider, Mafia Definitive Edition and Batman: Arkham Knight. Twenty titles fall below its minimum bar — Counter-Strike 2, Alan Wake 2 and every recent blockbuster among them — and the remaining 42 sit at the minimum tier. These verdicts are CPU-only, and with a median GPU score of just 14 across the roster, the whole machine, not only the processor, sets the limit.

Laptops that carry it

The 17-model roster is budget hardware from 2019–2021: Lenovo's V15-IIL at $264 and IdeaPad 3 at $373, Dell's Inspiron 15 3511 at $321 and Latitude 3420 and 3520 at $357, HP's 240 G7 at $339, 250 G7 and ProBook 450 G7 at $604, ASUS's VivoBook 14 X413 at $399, up to the IdeaPad Flex 5 convertible and HP 250 G8 at $666–$686. The laptops around it typically show a median office comfort of 75, a performance index of about 39, energy efficiency of 71 and portability of about 50 — basic machines for basic work, priced accordingly.

Bottom line

The Core i3-1005G1 is an honest budget part now in the bottom half of its useful life: ranked 354th of 737 with 7 of 69 games at the recommended CPU tier, it suits browsing, documents, streaming video and schoolwork on the cheapest machines in the catalog — the $264–$399 models here fit that brief exactly. Anything heavier calls for a step up, and even a modest one buys a visibly smoother machine.
