Quick Answers

Which GPU is faster for gaming right now?

Radeon R9 M485X is the faster gaming card right now. In our data, it leads by 20.6% in average FPS across 50 tracked games in our benchmark data and by 2.2% in PassMark G3D (3,801 vs 3,720), so the answer here is pretty clean.

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

GeForce MX450 is the safer long-term pick for 2026 and beyond. The case is simple: a 12nm process instead of 28nm and a newer 2020 generation instead of 2016. 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 to buy today. It is $200 cheaper on MSRP at $250 vs $450, and it leads G3D-per-dollar by 76.2% (14.9 vs 8.4), which is enough to swing the recommendation its way. Radeon R9 M485X still makes more sense if max raw gaming performance matters more than value.
