Quick Answers

Which GPU is faster for gaming right now?

GeForce MX450 is the faster gaming card right now. In our data, it leads by 3.5% in average FPS across 18 tracked games in our benchmark data. PassMark G3D leans toward Radeon 840M instead at 3,803 vs 3,720, 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 840M 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 4nm process instead of 12nm, and a newer 2024 generation instead of 2020. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

GeForce MX450 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 MX450 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon 840M has the stronger long-term case.
