Quick Answers

Which GPU is faster for gaming right now?

GeForce RTX 3080 is the faster gaming card right now. In our data, it leads by 107.9% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward GeForce GTX 1080 SLI (móvel) instead at 26,543 vs 25,071, 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 3080 is the safer long-term pick for 2026 and beyond. The case is simple: the newer upscaling stack, DLSS 2 Super Resolution (2020) instead of no meaningful modern upscaling stack, a 8nm process instead of 16nm, 68 vs 0 ray-tracing units, and a newer 2020 generation instead of 2016. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

GeForce RTX 3080 makes the most sense today based on the pricing and value data we have for this matchup.
