Quick Answers

Which GPU is faster for gaming right now?

RADEON X700 PRO is the faster gaming card right now. In our data, it leads by 2.0% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward GeForce 8400 instead at 81 vs 76, 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 X700 PRO 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 no meaningful modern upscaling stack, a 5nm process instead of 28nm, 80 vs 0 ray-tracing units, and a newer 2023 generation instead of 2014. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

GeForce 8400 makes the most sense to buy today. It is $134 cheaper on MSRP at $45 vs $179, and it leads G3D-per-dollar by 323.9% (1.8 vs 0.4), which is enough to swing the recommendation its way. If you are mainly targeting 1080p and some 1440p, GeForce 8400 is the easier value choice. If you care more about 1080p and some 1440p headroom, RADEON X700 PRO has the stronger long-term case.
