Quick Answers

Which GPU is faster for gaming right now?

Radeon X1650 SE 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 and by 6% in PassMark G3D (71 vs 67), so the answer here is pretty clean.

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

Radeon X1650 SE is the safer long-term pick for 2026 and beyond. The case is simple: 512 MB vs 256 MB of VRAM, the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 7nm process instead of 28nm, and a newer 2023 generation instead of 2014. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

GeForce 8400M GT 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, GeForce 8400M GT is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon X1650 SE has the stronger long-term case.
