Radeon HD 7420G: FPS benchmarks and laptop guide
Radeon HD 7420G — 12 games benchmarked at 1080p, 2 models in the catalog.
Radeon HD 7420G — 12 games benchmarked at 1080p , 2 laptop models in the used-laptop catalog . This guide covers what the chip delivers in games, where it sits among mobile GPUs in 2026, and which laptops carry it.
The Radeon HD 7420G is the smaller Llano integrated part of AMD's 2012 APU generation — 128 shader cores against its 192-core sibling, in the same value-business chassis. This guide covers its 12 recorded game benchmarks at 1080p and its two hosts.
Where the HD 7420G sits in 2026
The composite ranks it #315 of 341 (score 1.6). The neighbors: R7 M365X (#312, 2.1), UHD Graphics 605 (#313, 1.8) and HD 6630M (#314, 1.7) above; the NVS 4200M (#316, 1.6), UHD Graphics 600 (#317, 1.6) and HD 8330 (#318, 1.4) below. Curiously it ranks twelve places above the 192-core HD 7520G (#327) — the smaller Llano recorded ahead of the bigger one, a record-level artifact worth noting rather than explaining away.
What the chip brings
The record lists 128 shader cores, a 35W APU envelope, a 32nm process and 0.17 TFLOPS. Public benchmarks: PassMark 314, Fire Strike 343 — near-identical to the 7520G's 317, which says the two trims were closer in practice than their core counts suggest.
FPS in games at 1080p
The recorded table matches the 7520G's frame for frame: legacy ceilings (CS:GO/Overwatch 240, GTA V/PUBG 140), Valorant 27, Dota 2 12, The Witcher 3 6, Forza Horizon 4 5, Counter-Strike 2 3, Cyberpunk 2077 1, Fortnite 1, Metro Exodus 1. One table, two trims — the catalog's shared-baseline pattern at the bottom tier.
Laptops that carry it
Two hosts: the HP ProBook 6475b ($135) — shared with the 7520G record, the same chassis carrying both APU trims — and the ProBook 645 G1 ($127). Two business notebooks, one family, two recorded names.
Bottom line
The HD 7420G and 7520G tell one story from two records: Llano integrated graphics, bottom-tier table, honest $127-135 business chassis. Whichever name a listing carries, the experience recorded here is the same — and the twelve-place ranking gap between the trims is a catalog artifact, not a buying signal.
