Radeon R7 M340: FPS benchmarks and laptop guide

The Radeon R7 M340 is a 2015 entry-level discrete GPU from AMD's OEM lineup — a low-clocked GCN part sold into budget 15/17-inch laptops to add a "dedicated graphics" line to the spec sheet. This guide covers its 35 benchmarked games at 1080p on high and the 2 catalog listings matched to it.

Where the Radeon R7 M340 sits in 2026

With a catalog score of 3.2, the R7 M340 ranks 291st of 341 — the bottom tenth of the table, in one of its most crowded neighborhoods: the Radeon Vega 3 (3.4) and Quadro 3000M (3.4) above, the Radeon R5 M430 (3.2), UHD Graphics 617 (3.2), GeForce GT 750M (3.2) and NVS 5400M (3.0) packed immediately around and below it. That congestion is the legacy-OEM tier in miniature — dozens of near-identical chips separated by fractions of a point, all long since passed by ordinary integrated graphics.

What the chip brings

The M340 is a GCN 3.0 design (codenamed Meso) on the 28nm process: 320 shader cores clocked at up to 1021MHz, 4GB of DDR3 memory on a 64-bit bus moving just 16GB/s, and peak throughput of 0.65 teraflops. PassMark rates it at 644 and Fire Strike at 1209 — figures that place it among the slowest discrete records in the catalog. The one medium-preset measurement in the record is a courtesy; this chip lived its life on low settings.

FPS in games at 1080p

The high-preset table has a short honest band: F1 2014 at 41 fps, Valorant at 35, GRID: Autosport at 27, The Sims 4 at 25, Dirt Rally and DOTA 2 at 21, Alien: Isolation and World of Warships at 17. From there the numbers become a caution against trying: Battlefield Hardline and Metal Gear Solid V at 13, Fortnite at 6, Forza Horizon 4 at 9, The Witcher 3 at 7, Cyberpunk 2077 at 3, and Counter-Strike 2 and the Resident Evil 4 remake at 1 fps.

Laptops that carry it

Two listings: HP's 17-bs153cl, a 2017 17-inch consumer machine at $309, and the ProBook 450 G3, a 2015 business laptop at $195. Both used the M340 as the graphics-upgrade checkbox in otherwise ordinary configurations. The roster medians (best-GPU score 3.2, gaming index 11) align with the chip itself here — these machines never had a stronger GPU tier worth conflating.

Bottom line

The R7 M340 is spec-sheet decoration, and it was barely more than that when new. The two machines carrying it are basic consumer and business laptops from the mid-2010s, worth their low prices for casual use — but the GPU row contributes nothing to that value. In 2026 it handles video decode and desktop compositing, and any game newer than 2014 is out of the question.
