Quick Answers

Which GPU is faster for gaming right now?

Radeon HD 4850 is the faster gaming card right now. In our data, it leads by 21.2% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Radeon 620 instead at 954 vs 946, 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 620 is the safer long-term pick for 2026 and beyond. The case is simple: a 28nm process instead of 55nm and a newer 2019 generation instead of 2008. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Radeon 620 makes the most sense to buy today. It is $99 cheaper on MSRP at $100 vs $199, and it leads G3D-per-dollar by 100.7% (9.5 vs 4.8), which is enough to swing the recommendation its way. Radeon HD 4850 still makes more sense if max raw gaming performance matters more than value.
