Quick Answers

Which GPU is faster for gaming right now?

GeForce RTX 3070 is the faster gaming card right now. In our data, it leads by 1840.9% in average FPS across 50 tracked games in our benchmark data and by 2224.1% in PassMark G3D (22,172 vs 954), so the answer here is pretty clean.

Which GPU is the safer long-term pick for 2026 and beyond?

GeForce RTX 3070 is the safer long-term pick for 2026 and beyond. The case is simple: 8 GB vs 512 MB of VRAM, a 8nm process instead of 28nm, 46 vs 0 ray-tracing units, and a newer 2020 generation instead of 2019. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

GeForce RTX 3070 makes the most sense to buy today. It is $399 more expensive on MSRP at $499 vs $100, and it leads G3D-per-dollar by 365.8% (44.4 vs 9.5), so the value case lines up with the gaming result.
