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 228.2% in average FPS across 50 tracked games in our benchmark data and by 186.9% in PassMark G3D (22,172 vs 7,728), so the answer here is pretty clean.

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

Radeon RX 6400 is the safer long-term pick for 2026 and beyond. The case is simple: the newer feature stack, with FSR 3 (2023) and FSR Frame Generation + AFMF (2023), while GeForce RTX 3070 is limited to DLSS 2 Super Resolution (2020) and no comparable frame-generation support, a 6nm process instead of 8nm, and a newer 2022 generation instead of 2020. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Radeon RX 6400 makes the most sense to buy today. It is $340 cheaper on MSRP at $159 vs $499, and it leads G3D-per-dollar by 9.4% (48.6 vs 44.4), which is enough to swing the recommendation its way. GeForce RTX 3070 still makes more sense if max raw gaming performance matters more than value.

Advanced Features (DLSS/FSR)

The clearest feature edge for the Radeon RX 6400 is support for FSR Frame Generation + AFMF. In games that support it, that can smooth out motion and lift perceived FPS. The GeForce RTX 3070 does not have comparable native support in the same tier.The GeForce RTX 3070 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.
