GeForce RTX 4090: FPS benchmarks and laptop guide

The GeForce RTX 4090 laptop chip is the biggest GPU ever put in a portable — the full AD102 die with 16,384 shader cores and a terabyte-per-second memory system. The catalog matches 42 models to it, with benchmarks in 117 games at 1080p. This guide covers its 2026 ranking, its frame rates and the desktop-replacement machines that carry it.

Where the RTX 4090 sits in 2026

This record scores 75.0 and ranks 22nd of 341 scored mobile GPUs, alongside the RTX A4000 (75.6), Radeon RX 6800M (75.1), RTX 2080 (75) and the RTX 4070 Laptop record (74.6). The honest footnote: the same silicon holds a second catalog record under its laptop name at 84.9 — fifth place, the consumer ceiling — and the gap between the two records is the largest implementation spread of any chip on the site. A 4090 in a thick chassis with full cooling and a 120 W budget is a different machine from one squeezed into a slim body; the rankings reflect which examples fed which record.

What the chip brings

The specification is halo-tier everything: the AD102 die on a 4 nm-class process, 16,384 shader cores, 16 GB of GDDR6 on a 384-bit bus moving a terabyte per second, over 82 TFLOPS of theoretical throughput and a 120 W-class thermal design. Ray tracing cores, DLSS frame generation, Resizable BAR and CUDA compute complete the stack, and the 16 GB pool doubles the memory of most of the table. Public benchmarks for this record: around 27,000 PassMark points and a 3DMark Time Spy graphics score near 21,300.

FPS in games at 1080p

At 1080p the chip is CPU-bound in most of the table: the Witcher 3 runs 394 FPS at the high preset, Diablo 4 361 rising to 374 on medium, Valorant 350, the Rainbow Six Extraction record 346, F1 2020 344, Counter-Strike 2 and Fortnite 300 each, Forza Horizon 5 281 and Hunt Showdown 262. The demanding catalog is equally one-sided — the Resident Evil 4 remake at 218 rising to 190, God of War at 167 rising to 177, Far Cry 5 at 173, Metro Exodus at 156 rising to 161, Cyberpunk 2077 at 147 rising to 107, Dying Light 2 at 145 rising to 197 and The Last of Us at 103 rising to 111. Elden Ring sits at its engine's 60 cap. The honest number for 2026: this chip's real workload begins where 1080p ends.

Laptops that carry it

The 42-model roster is the 2024 halo class, and the pricing is strikingly uniform: ASUS ROG Strix SCAR 16 and SCAR 18, the ROG Zephyrus G16, Acer Predator Helios 18 and a deep MSI contingent — Raider 18 HX and A18 HX, Titan 18 HX, Vector 16 and 17 HX, Stealth 16 and Creator 16 AI Studio — all cluster at $1,152. The Alienware M18 R2 tops the roster at $2,485. Roster medians: best-CPU score 94, gaming index 79, 64 games clearing recommended settings, portability 16.7 — uncompromised machines built to feed the die.

Bottom line

A used RTX 4090 laptop at $1,152 is the most performance money can buy in the catalog — a terabyte of memory bandwidth, 16 GB of VRAM and frame rates that make 1080p look easy, in machines that also carry the strongest mobile processors. The catch is written in the rankings: implementation variance is enormous at this tier, so the specific chassis matters more here than anywhere else. Buyers eyeing the 4080 tier one step down should weigh the doubled memory and extra headroom against the price gap; buyers below that should read the compare pages first — this is the ceiling, and everything else measures against it.
