Quick Answers

Which GPU is faster for gaming right now?

Radeon RX 6400 is the faster gaming card right now. In our data, it leads by 32.0% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Radeon 880M instead at 7,729 vs 7,728, 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 880M is the safer long-term pick for 2026 and beyond. The case is simple: the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of FSR 3 (2023), a 4nm process instead of 6nm, and a newer 2024 generation instead of 2022. 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 today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p and some 1440p, Radeon RX 6400 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon 880M has the stronger long-term case.
