Quick Answers

Which GPU is faster for gaming right now?
Mobility Radeon HD 3430 is the faster gaming card right now based on the synthetic data we have. It leads by 4.3% in PassMark G3D (98 vs 94), which is the best performance signal available in this matchup.
Which GPU is the safer long-term pick for 2026 and beyond?
GeForce 9400M G is the safer long-term pick for 2026 and beyond. The case is simple: a 28nm process instead of 55nm and a newer 2015 generation instead of 2009. That makes it the less risky pick as game demands keep moving.
Which GPU is the better buy today?
Mobility Radeon HD 3430 makes the most sense to buy today. It is $1 cheaper on MSRP at $49 vs $50, and it leads G3D-per-dollar by 6.4% (2.0 vs 1.9), so the value case lines up with the gaming result. If you are mainly targeting 1080p and some 1440p, Mobility Radeon HD 3430 is the easier value choice. If you care more about 1080p and some 1440p headroom, GeForce 9400M G has the stronger long-term case.
