GeForce GTX 1080 SLI (móvel) vs GeForce RTX 4090 Mobile: Pros, Cons & Final Verdict

See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

GeForce GTX 1080 SLI (móvel)

2016

Why buy it

  • Competitive enough if your priority is price, power, or specific feature preference.

Trade-offs

  • Lower average FPS than GeForce RTX 4090 Mobile across 50 tracked games in our benchmark data.
  • No equivalent frame-generation stack like DLSS 3.5 + Frame Generation (2023).
  • Older hardware, 16 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
  • 150% higher power demand at 300W vs 120W.

GeForce RTX 4090 Mobile

2023

Why buy it

  • 139.8% more average FPS across 50 tracked games in our benchmark data.
  • Access to a newer frame-generation stack with DLSS 3.5 + Frame Generation (2023).
  • Better long-term bet: Ada Lovelace (2022−2024) on 4nm gives it a newer hardware base for upcoming games.
  • Draws 120W instead of 300W, a 180W reduction.

Trade-offs

  • Fewer clear downsides in this head-to-head, aside from the usual pricing and availability swings.

Quick Answers

Which GPU is faster for gaming right now?
GeForce RTX 4090 Mobile is the faster gaming card right now. In our data, it leads by 139.8% in average FPS across 50 tracked games in our benchmark data and by 1.9% in PassMark G3D (27,048 vs 26,543), so the answer here is pretty clean.
Which GPU is the safer long-term pick for 2026 and beyond?
GeForce RTX 4090 Mobile is the safer long-term pick for 2026 and beyond. The case is simple: the newer feature stack, with DLSS 3.5 Super Resolution (2023) and DLSS 3.5 + Frame Generation (2023), while GeForce GTX 1080 SLI (móvel) is limited to no meaningful modern upscaling stack and no comparable frame-generation support, a 4nm process instead of 16nm, 76 vs 0 ray-tracing units, and a newer 2023 generation instead of 2016. That gives it the more rounded hardware package for newer games.
Which GPU is the better buy today?
GeForce RTX 4090 Mobile makes the most sense today based on the pricing and value data we have for this matchup.
