GeForce 840M: FPS benchmarks and laptop guide

The GeForce 840M is NVIDIA's mainstream Maxwell discrete GPU from 2014 — for years the default "a little better than integrated" option in mid-range laptops. (Don't confuse it with AMD's 2025 Radeon 840M: same name, different vendor, eleven years apart.) This guide covers its 39 benchmarked games at 1080p on high and the 7 catalog listings matched to it.

Where the GeForce 840M sits in 2026

A catalog score of 5.8 ranks the 840M at 271st of 341 — deep in the bottom fifth. Its neighbors: the GeForce 940M (6.2), Radeon Pro WX 4150 (6.2) above, and the Iris Graphics 540 (5.6), Quadro K3000M (5.5) and Radeon 8050S (5.5) below. The pattern repeats across this era of entry discrete cards: they once justified their existence against weak integrated graphics, and modern baseline silicon has simply absorbed their performance level.

What the chip brings

This is the GM108S cut of first-generation Maxwell on the 28nm process: 384 shader cores, a boost clock of 1124MHz, and a 33W envelope. The memory story is the classic budget compromise of its day — 4GB of DDR3 on a 64-bit bus, giving just 16GB/s of bandwidth. The capacity looked good on the sticker; the bandwidth was the real constraint. Peak throughput lands at 0.86 teraflops, with PassMark at 1098 and Fire Strike at 1573.

FPS in games at 1080p

The 840M's table divides cleanly at 2015. Older titles play fine on high: F1 2014 at 58 fps, Valorant at 40, World of Warships at 37, The Sims 4 at 31, DOTA 2 at 27, Call of Duty: Advanced Warfare and Dirt Rally at 23. Modern games are effectively off the menu: Fortnite at 14, Forza Horizon 4 at 12, The Witcher 3 at 9, Counter-Strike 2 at 8, Cyberpunk 2077 at 5 and the Resident Evil 4 remake at 3 fps. There is no medium-preset column in this record — high is all the data there is.

Laptops that carry it

Seven listings, spanning $120–381 and mostly 2015-vintage: Dell's Latitude E7450 ($120), E5450 ($136) and E5550 ($245); HP's Pavilion 15-p258nl ($381); Lenovo's IdeaPad Z710 ($207); and Dell's Inspiron 15 3542 ($123) and Inspiron 17 5748. The corporate Latitudes remain the interesting picks — well-built machines at triple-digit prices where the 840M was the GPU upgrade option. As always with these rosters, the models' catalog medians reflect their full option range, not this chip's configurations.

Bottom line

In 2026 the 840M is a footnote in laptop history: the GPU that millions of people owned without ever thinking about it. The machines it lived in are still serviceable as web and office computers, and the chip handles video playback and multi-monitor duty without complaint. But as gaming hardware it's a decade past relevance — if a listing's pitch is "it has a dedicated graphics card," that card is this one, and it changes nothing. Buy the chassis, ignore the GPU.
