Ryzen AI 5 340: CPU benchmarks and laptop guide

The AMD Ryzen AI 5 340 is the value entry into the Ryzen AI 300 generation — 50 catalog models carry it. A 6-core, 12-thread design on a 4 nm process with the Radeon 840M integrated graphics, it meets the recommended CPU requirement in 68 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 Ryzen AI 5 340 sits in 2026

A catalog score of 82.5 places the chip 34th of 672 scored laptop CPUs — the top five percent. The neighborhood is stacked with pricier silicon: the Core Ultra 7 256V (83.9), Core Ultra 7 258V (83.9) and Ryzen 5 7640HS (82.6) just above, the Ryzen 7 PRO 7840U (81.6), Ryzen 7 8840U (81.6) and Ryzen 5 PRO 7640HS (81.2) just below. Outranking 7840U-class 8-core parts from a 6-core budget position is the chip's argument: current-generation architecture doing the heavy lifting that core count used to do.

What the chip brings

Krackan Point pairs 6 cores and 12 threads on a 4 nm process at a 28 W P-class rating: 2 GHz base, up to 4.8 GHz boost. The integrated Radeon 840M clocks to 2,900 MHz — quick for integrated graphics and the reason the cheaper entries in this roster work without a discrete GPU. GeekBench places the chip at 2,344 single-core and 9,186 multi-core: single-thread performance within a few percent of the flagship 350, multi-thread honestly reflecting the two fewer cores.

Games: CPU-side readiness

As a processor, the chip clears the recommended CPU tier for 68 of 69 cataloged games — Cyberpunk 2077, Baldur's Gate 3, Elden Ring and Fortnite included. The single miss is Starfield, above its minimum but under its recommended CPU requirement. These verdicts are CPU-only: on the integrated-Radeon entries the 840M handles display duty, and real frame rates in heavy titles depend on the discrete GPU and RAM of the specific laptop.

Laptops that carry it

The 50-model roster leans everyday-premium: the Zenbook S 16, Zenbook 14 OLED and Acer Swift lines at $1,232, ThinkPad T16 Gen 4 at $1,284, and the Vivobook 14/16/S14 trio at $765 — the cheapest current-generation ticket in the catalog's top tier. Roster medians read balanced rather than extreme: office comfort a perfect 100, energy efficiency 87.2, photo and design 79, mobility 73 — with gaming index 21, because most of these machines run integrated graphics.

Bottom line

The Ryzen AI 5 340 is the smart-money entry into the current AMD generation: within a handful of ranking places of chips costing hundreds more, recommended-tier CPU clearance for everything but Starfield, and a $765 Vivobook floor that undercuts every neighbor in its bracket. Buyers who need the multi-thread headroom should step up to the Ryzen AI 7 350; everyone else is paying for cores they will not miss. The compare pages against the 350 and the Ryzen 7 7730U draw the line precisely.
