Radeon 840M: FPS benchmarks and laptop guide

First, a disambiguation: the Radeon 840M is AMD's 2025 integrated graphics, part of the Krackan Point silicon inside current thin-and-light laptops. It shares its name with NVIDIA's GeForce 840M from 2014 — eleven years and an entirely different vendor apart. This guide covers the modern AMD part: 46 games benchmarked at 1080p on the high preset (with medium-preset data for 31 of them) and 31 catalog models that carry it.

Where the Radeon 840M sits in 2026

With a catalog score of 18.5, the Radeon 840M ranks 214th of 341 — respectable territory for integrated graphics. Its immediate neighbors are the Radeon Pro WX 3100 and Apple A12Z (both 18.8) and the Radeon Vega 10 (18.6) above, with the Quadro M1200 and M620 (18.4) and the GeForce GTX 850M (18.2) below. The pattern in that list is telling: a 2025 integrated GPU comfortably matches entry-level discrete cards from the mid-2010s while sipping 15 watts.

What the chip brings

This is RDNA 3.5 architecture on TSMC's 4nm process — the same generation of graphics silicon AMD ships across its current mobile lineup. The configuration here is deliberately small: 256 shader cores with a boost clock up to 2900MHz, sharing system memory rather than carrying its own. The 15W envelope is the whole point: it lives inside processors built for fanless-adjacent thin machines. Its PassMark rating of 3797 and Fire Strike score of 4854 confirm the positioning — triple the R7 M460-class silicon of a decade ago, at a third of the power.

FPS in games at 1080p

At the high preset, esports titles are genuinely playable: Prince of Persia: The Lost Crown runs at 114 fps (rising to an estimated 163 on medium), Valorant at 85, Counter-Strike 2 at 84, DOTA 2 Reborn at 57 and Fortnite at 55. Middleweight titles land in the 27–40 range — Battlefield 5 and Forza Horizon 4 at 40, Far Cry 5 at 30, Baldur's Gate 3 at 27 (32 on medium). The frontier stops there: Cyberpunk 2077 manages 18 fps on high and the Resident Evil 4 remake 16. This is a chip for competitive titles and well-optimized engines, not maximum-detail AAA gaming.

Laptops that carry it

Every model in the displayed roster is a 2026 machine — exactly what you'd expect from current silicon: Acer's Aspire 16 AI at $900 and Aspire 14 AI at $1400, Lenovo's Yoga 7a Gen 11 convertibles and IdeaPad 5a 2-in-1s around $1500, the ThinkPad T14s Gen 7 at $1300, and on the professional side HP's ZBook 8 G2a workstations at $2200 plus EliteBook X G2a business machines. The roster medians describe this fleet well: a portability index of 65.9 and energy efficiency of 87.2 — these are machines bought for battery life and portability first, with the GPU as capable backup.

Bottom line

If you're shopping the 2026 thin-and-light segment, the Radeon 840M is the graphics you'll likely get by default, and it's a perfectly good deal: esports at high 1080p, modern indies and older AAA titles at comfortable frame rates, and zero additional power draw. Just don't mistake it for a gaming rig — its ceiling is competitive titles and disciplined engines. For heavier rendering, the same money in a thicker chassis buys a discrete GPU that will run rings around it.
