GeForce 8400M GS: FPS benchmarks and laptop guide

The GeForce 8400M GS is the second-weakest record in this catalog's entire 341-chip ranking — 16 cores from 2007, the halved sibling of the 8600M GT. This guide covers its 10 recorded game benchmarks at 1080p and its single catalog host.

Where the 8400M GS sits in 2026

The composite ranks it #340 of 341 (score 0.2). Above it: the 8600M GT (#337, 0.4), HD 6320 (#338, 0.4) and Mobility HD 4530 (#339, 0.4); below it only the Quadro K1100M record (#341, 0.2) — a part whose composite, as documented elsewhere in this catalog, badly understates its own game table. Second-to-last is where 2007's smallest shader count lands in 2026.

What the chip brings

The record lists 16 CUDA cores, DDR2 memory, an 80nm process, an 11W envelope and 0.026 TFLOPS. Public benchmark: PassMark 100 — the lowest figure recorded anywhere in this catalog. This was the display-adapter tier of its generation: enough for Vista's glass effects and video decode, nothing more.

FPS in games at 1080p

At the high preset: legacy ceilings (CS:GO/Overwatch 240, GTA V/PUBG 140), Valorant 24, Dota 2 9, The Witcher 3 5, Forza Horizon 4 3, Counter-Strike 2 2, Fortnite 1, Cyberpunk 2077 1. The Dota 2 row at 9 is the lowest on any page in this batch — the honest floor of the entire bottom tier.

Laptops that carry it

One host: the Dell Inspiron 1520 — the 15-inch consumer laptop of 2007-08, recorded without a price. The same chassis generation as the 8600M GT's Inspiron 1720 one rung up: one screen size apart, one shader halving apart.

Bottom line

The 8400M GS is a display adapter that can also run old games: 16 cores, a PassMark of 100, and second-to-last place in a ranking that spans nineteen years. Its single host is a collector's machine — and this page is the complete, honest specification of what that machine can play.
