Core i3-N305: CPU benchmarks and laptop guide

The Intel Core i3-N305 is an Alder Lake-N processor from 2023 — eight efficiency cores on a 15-watt budget, built for inexpensive thin laptops. It appears in 18 catalog models, and measured as a processor it clears the recommended CPU tier in 36 of the 69 games the catalog tracks. This guide covers where the chip sits among laptop CPUs, what it brings, and which laptops carry it.

Where the Core i3-N305 sits in 2026

A catalog score of 53.4 places the chip 229th of 741 scored laptop CPUs — the middle of the table. The neighborhood reaches back a few years: the Core i5-9400H (53.7), Core i5-10200H (53.5) and Xeon E3-1545M v5 (53.4) just above, the Ryzen AI 5 435 (53.3) and Xeon E3-1535M v5 and v6 (53.2) just below. Matching 2019-era 45-watt gaming-class i5s on a fraction of the power is the chip's whole story — efficiency-first design that trades peak speed for battery life and price.

What the chip brings

Alder Lake-N is an unusual design: 8 cores and 8 threads — all efficiency cores, no performance cores — on a 7 nm-class process, boosting up to 3.8 GHz inside a 15 W envelope. Public benchmark results read 1,140 single-core and 4,190 multi-core on the GeekBench scale, a profile that leans on thread count rather than per-core speed. Memory and graphics details were not captured for this entry, so the table above sticks to what the catalog verifiably holds.

Games: CPU-side readiness

Measured purely as a processor, the chip clears the recommended CPU tier for 36 of 69 cataloged games — including Dying Light 2, Far Cry 5, Diablo 4, F1 24, Flight Simulator 2020, Doom Eternal, Grand Theft Auto V and Civilization 6. The tier just below is broad: Cyberpunk 2077, Counter-Strike 2, Red Dead Redemption 2, The Witcher 3 and PUBG all list it above minimum but below recommended. Starfield, Helldivers 2, Baldur's Gate 3, Elden Ring and Fortnite ask for more than it delivers even at minimum. These verdicts are CPU-only — the laptop's GPU and RAM decide actual playability, and N-series machines almost always ship with integrated graphics.

Laptops that carry it

The 18-model roster is modern budget territory: ASUS Vivobook Go 14 and Go 15 OLED from $246, Acer Aspire 3 and Aspire 3 Spin 14, Lenovo IdeaPad Slim 3i in 14- and 15-inch sizes, HP Laptop 14 and 17 at $553, the HP Pavilion SE 14 at $650, Acer Aspire Go 15 up to $765, and the HP 250 G10 business machine at $886 — spanning 2023 to 2025. The laptops built around it typically show a median office comfort score of a perfect 100, energy efficiency of 86.5, mobility of 61.5 — but a gaming index of just 29, confirming the graphics-light, battery-first character of these machines.

Bottom line

The Core i3-N305 is a chip for buyers who value battery life, quiet operation and price over speed: it clears the recommended CPU tier for half the game catalog at a 15 W draw, in laptops from $246 to $886. What it cannot do is single-core muscle — the heaviest modern titles sit beyond its minimum tier, and the machines around it rarely carry a GPU to compensate. For study, office work and older or lighter games, it is an honest, efficient choice.
