Ryzen 3 5400U: CPU benchmarks and laptop guide

The AMD Ryzen 3 5400U brought the Zen 3 architecture to the budget end of the 2021 ultrabook market, and six catalog laptops carry it — HP EliteBooks and ProBooks plus Lenovo ThinkPad L-series machines. As a processor it meets the recommended CPU tier in 49 of the 69 games the catalog tracks, an unusually strong showing for a chip with "Ryzen 3" on the lid. This guide covers its ranking, its specifications and the laptops built around it.

Where the Ryzen 3 5400U sits in 2026

A catalog score of 58.3 places the chip 184th of 741 scored laptop CPUs — the upper third of the table. The neighborhood is remarkable for a budget part: the Ryzen 3 5425U (58.5), Ryzen 7 250 (58.4) and Core i7-12700H (58.4) sit just above, while the Ryzen 5 4600U (58.1), Core Ultra 7 155H (58) and Core i5-13450HX (58) sit just below. Scoring level with a 14-core H-class gaming processor while running at a fraction of the wattage is the whole Zen 3 proposition: modest silicon, used extremely well.

What the chip brings

Cezanne is a four-core, eight-thread design on a 7 nm process with a 15 W U-class rating: 2.6 GHz base and up to 4.0 GHz boost. The integrated Radeon Graphics with 384 shader processors handles everyday display work and light titles. Public benchmarks read 1,453 single-core and 4,345 multi-core in Geekbench — the single-core figure is the highlight, competitive with mainstream chips several price tiers up.

Games: CPU-side readiness

Measured as a processor alone, the chip clears the recommended CPU tier for 49 of 69 cataloged games — including Counter-Strike 2, Metro Exodus, PUBG: Battlegrounds, Ghost of Tsushima, Black Myth Wukong, Returnal, The Last of Us Part 1 and Dead Space Remake. A second group sits at the minimum tier: Cyberpunk 2077, Baldur's Gate 3, Elden Ring, Fortnite, Hogwarts Legacy, Apex Legends and Red Dead Redemption 2 all list it above minimum but below recommended. Only Starfield and Helldivers 2 ask for more processor than this. These are CPU-only verdicts — actual playability depends on the laptop's GPU and RAM, and every machine in this roster relies on the modest integrated Radeon graphics.

Laptops that carry it

All six catalog machines are business portables from 2020–2021: HP's EliteBook 845 G8 at $309 and ProBook 445 G8 at $256, the ProBook 440 G9 at $317, Lenovo's ThinkPad L14 Gen 2 at $345 and ThinkPad L14 at $328, plus the ThinkPad L13 Yoga Gen 2 convertible at $410. The laptops built around it typically show a median best CPU score of 68.9, office comfort of 97.5, energy efficiency of 88.9 and mobility of 75.5 — a fleet tuned for battery life and work, not frames. The median best GPU score of 14.6 and gaming index of 44 underline that integrated graphics remain the ceiling.

Bottom line

The Ryzen 3 5400U is proof that the budget end of 2021 aged gracefully: processor-side it handles nearly the whole tracked game catalog at recommended CPU settings, and the business laptops carrying it deliver excellent efficiency and comfort in the $256–$410 used range. It suits students, office buyers and anyone wanting a quiet long-lasting daily machine that can still dabble in esports titles. What it cannot promise is graphics muscle — for gaming beyond light titles, a discrete-GPU laptop further up the table is the better spend.
