Quick Answers

Which GPU is faster for gaming right now?

Radeon HD 6790 is the faster gaming card right now. In our data, it leads by 10.6% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Radeon 630 instead at 1,575 vs 1,567, 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 630 is the safer long-term pick for 2026 and beyond. The case is simple: a 14nm process instead of 40nm and a newer 2019 generation instead of 2011. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Radeon 630 makes the most sense to buy today. It is $49 cheaper on MSRP at $100 vs $149, and it leads G3D-per-dollar by 49.8% (15.8 vs 10.5), which is enough to swing the recommendation its way. Radeon HD 6790 still makes more sense if max raw gaming performance matters more than value.
