Iris Plus Graphics 645: FPS benchmarks and laptop guide
Iris Plus Graphics 645 — 17 games benchmarked at 1080p.
Iris Plus Graphics 645 — 17 games benchmarked at 1080p . This guide covers what the chip delivers in games, where it sits among mobile GPUs in 2026, and which laptops carry it.
The Iris Plus Graphics 645 is one of Intel's Generation 9.5 integrated GPUs, the base graphics of the 2019 13-inch premium ultrabook tier. This benchmark-only page covers its 17 games at 1080p (16 on the high preset, one with medium data); no laptop model in the catalog is matched to this chip record.
Where the Iris Plus Graphics 645 sits in 2026
A catalog score of 15.5 ranks it 230th of 341 — below the middle. The neighborhood is a collision of eras: the RTX A500 (15.8) and Quadro M1000M (15.8) above, its own sibling Iris Plus 650 (15.6) just above, then the MX570 A (15.2), Radeon Vega 8 (14.8) and Quadro K4100M (14.6) below. A 2019 thin-and-light iGPU ranked level with 2015 professional cards and modern entry discrete options — fair for a 15W part.
What the chip brings
Generation 9.5 architecture on 14nm with system-shared memory in a 15W envelope. Public benchmarks: PassMark 1730, Time Spy 550, Fire Strike 1893, compute at 7811 (Vulkan) and 6359 (OpenCL). The 645 sat one SKU below the 650 in the same family — the difference between the tiers is modest, as their adjacent ranking shows.
FPS in games at 1080p
At the high preset: the legacy capped titles at 240/140, Valorant at 55, DOTA 2 at 29, Fortnite at 24, X-Plane 11 at 23 (26 on medium — a coherent headroom step), Forza Horizon 4 at 20, Counter-Strike 2 at 18, Battlefield 5 at 16. The heavy tier is not viable: The Witcher 3 and Far Cry 5 at 12, Forza Horizon 5 at 10, Cyberpunk 2077 at 8, the Resident Evil 4 remake at 6 and Metro Exodus at 8 fps. Light esports at 1080p, lighter titles on medium — the honest ceiling of the class.
Bottom line
The Iris Plus 645 is a display-first integrated GPU with a modest esports habit. Its table clears Valorant and DOTA 2 comfortably and nothing modern at 1080p high. For 2026 shoppers the machines carrying it are seven-year-old premium ultrabooks — buy them for build and battery, consult the table below for what to expect, and treat any gaming ambition as strictly 720p territory.
