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 1423.3% in average FPS across 50 tracked games in our benchmark data and by 1395.5% in PassMark G3D (26,919 vs 1,800), 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 512 MB of VRAM, native frame generation with DLSS 3.5 + Frame Generation (2023), while Radeon R6 M340DX has no comparable frame-generation support, a 5nm process instead of 28nm, and 46 vs 0 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.

Advanced Features (DLSS/FSR)

The clearest feature edge for the GeForce RTX 4070 is support for DLSS 3.5 + Frame Generation. In games that support it, that can smooth out motion and lift perceived FPS. The Radeon R6 M340DX does not have comparable native support in the same tier.The GeForce RTX 4070 gets NVIDIA DLSS, which still tends to look cleaner in motion. The Radeon R6 M340DX leans on FSR, which is flexible and widely supported, but usually a bit rougher at the same settings.
