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 244.4% in average FPS across 50 tracked games in our benchmark data and by 248.3% in PassMark G3D (26,919 vs 7,728), 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 4 GB of VRAM, a 5nm process instead of 6nm, 46 vs 12 ray-tracing units, and a newer 2023 generation instead of 2022. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon RX 6400 makes the most sense to buy today. It is $440 cheaper on MSRP at $159 vs $599, and it leads G3D-per-dollar by 8.2% (48.6 vs 44.9), which is enough to swing the recommendation its way. If you are mainly targeting 1080p and some 1440p, Radeon RX 6400 is the easier value choice. If you care more about 1080p and strong 1440p headroom, GeForce RTX 4070 has the stronger long-term case.

Advanced Features (DLSS/FSR)

Both GPUs support Frame Generation, but they get there through different ecosystems. The GeForce RTX 4070 uses DLSS 3.5 + Frame Generation, while the Radeon RX 6400 relies on FSR Frame Generation + AFMF. Both can help smooth out supported games, but they are not on the same feature stack.The GeForce RTX 4070 gets NVIDIA DLSS, which still tends to look cleaner in motion. The Radeon RX 6400 leans on FSR, which is flexible and widely supported, but usually a bit rougher at the same settings.
