Quick Answers

Which GPU is faster for gaming right now?

Radeon RX 6900 XT is the faster gaming card right now. In our data, it leads by 6.4% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward GeForce RTX 4070 instead at 26,919 vs 26,729, 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 4070 is the safer long-term pick for 2026 and beyond. The case is simple: a 5nm process instead of 7nm and a newer 2023 generation instead of 2020. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

GeForce RTX 4070 makes the most sense to buy today. It is $400 cheaper on MSRP at $599 vs $999, and it leads G3D-per-dollar by 68% (44.9 vs 26.8), which is enough to swing the recommendation its way. Radeon RX 6900 XT still makes more sense if max raw gaming performance matters more than value.
