Quick Answers

Which GPU is faster for gaming right now?

GeForce RTX 4070 is the faster gaming card right now. In our data, it leads by 655.7% in average FPS across 50 tracked games in our benchmark data and by 1112% in PassMark G3D (26,919 vs 2,221), so the answer here is pretty clean.

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: 12 GB vs 2 GB of VRAM, native frame generation with DLSS 3.5 + Frame Generation (2023), while RadeonT 660M has no comparable frame-generation support, a 5nm process instead of 6nm, and 46 vs 6 ray-tracing units. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

GeForce RTX 4070 makes the most sense today based on the pricing and value data we have for this matchup.
