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 2.8% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Radeon PRO W7800 instead at 27,180 vs 27,048, so for this question the real-game FPS result matters more than the synthetic split.

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: native frame generation with DLSS 3.5 + Frame Generation (2023), while Radeon PRO W7800 has no comparable frame-generation support, a 4nm process instead of 5nm, and 76 vs 70 ray-tracing units. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

Radeon PRO W7800 makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p and strong 1440p, Radeon PRO W7800 is the easier value choice. If you care more about 1080p and strong 1440p headroom, GeForce RTX 4090 Mobile has the stronger long-term case.
