Quick Answers

Which GPU is faster for gaming right now?

Radeon RX 5300 is the faster gaming card right now. In our data, it leads by 3.0% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Radeon RX 6400 instead at 7,728 vs 7,606, so for this question the real-game FPS result matters more than the synthetic split.

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: 4 GB vs 3 GB of VRAM, the newer frame-generation stack, FSR Frame Generation + AFMF (2023) instead of FSR Frame Generation (2023), a 6nm process instead of 7nm, and 12 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?

Radeon RX 5300 makes the most sense to buy today. It is $30 cheaper on MSRP at $129 vs $159, and it leads G3D-per-dollar by 21.3% (59.0 vs 48.6), so the value case lines up with the gaming result. If you are mainly targeting 1080p and some 1440p, Radeon RX 5300 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon RX 6400 has the stronger long-term case.
