Ryzen 3 4300U: CPU benchmarks and laptop guide

The AMD Ryzen 3 4300U was the budget entry of the Renoir generation — the 2020 lineup that made AMD a default choice in mainstream laptops. Four Zen 2 cores in a 15 W envelope put up a fight well above the chip's price class, and 10 catalog laptops carry it today. As a processor it clears the recommended CPU tier in 35 of the 69 games the catalog tracks. This guide covers where it sits among laptop CPUs, what it brings, and which laptops carry it.

Where the Ryzen 3 4300U sits in 2026

A catalog score of 50.4 places the chip 264th of 741 scored laptop CPUs — the middle of the table, which is remarkable for a 2020 budget part. The neighborhood proves the point: the Xeon E3-1505M v5 (50.8), Core i7-1260P (50.8) and Core Ultra 7 155U (50.5) sit just above, while the Core i7-6920HQ (50.2), Core i5-12450H (50.2) and Core i5-1240P (50) sit just below. A entry-level Renoir trading blows with 12th-generation Intel H- and P-series chips is the Renoir story in one line — that architecture has aged exceptionally well.

What the chip brings

Renoir-U is a 4-core, 4-thread Zen 2 design on a 7 nm process, rated at 15 W: a 2.7 GHz base clock that boosts to 3.7 GHz. There is no SMT — four cores, four threads — but the cores themselves are the same Zen 2 design AMD used across the generation. The integrated GPU is a Radeon RX Vega 3, a light iGPU better suited to video output than rendering. Public records show 1,261 single-core and 3,369 multi-core Geekbench-type scores; memory configuration details were not captured for this chip, so the table above sticks to what the catalog verifiably holds.

Games: CPU-side readiness

Measured purely as a processor, the chip meets the recommended CPU tier for 35 of 69 cataloged games — Far Cry 5, Doom Eternal, Death Stranding, Borderlands 3, God of War, GTA V and Civilization 6 among them. Another 27 sit at the minimum tier, including Cyberpunk 2077, Hogwarts Legacy, Counter-Strike 2 and PUBG. Seven titles fall below its reach — Starfield, Helldivers 2, Baldur's Gate 3 and Elden Ring among them. These verdicts are CPU-only: actual playability depends on the laptop's GPU and RAM, and the fleet around this chip is mostly iGPU-only hardware.

Laptops that carry it

The 10-model roster is textbook 2020 office hardware: Lenovo's ThinkPad E14 and E15 Gen 2, L14 and L15, ThinkBook 15 G2 and the IdeaPad 3 family, HP's ProBook 455 G7, plus a Dell Inspiron 5405 — one convertible in the mix, the IdeaPad Flex 5. Priced models run $264–$403. Laptops built around it typically show a median office comfort score of 75, energy efficiency at 89.1, mobility at 67 and portability near 49: efficient, light-duty machines. The gaming medians are modest, which matches the Vega 3 graphics most of these laptops rely on.

Bottom line

The Ryzen 3 4300U is one of the smartest cheap buys in the catalog: for $264–$403 it delivers 35 recommended-tier game clears on the CPU side, near-best-class efficiency and solid office comfort — performance that still matches Intel chips several generations younger. It is not a gaming platform: the Vega 3 iGPU and the thin business chassis around it cap what actually renders on screen. But as a processor for study, office work and occasional light gaming, it punches far above its 2020 budget positioning, and the ranking proves it.
