Quick Answers

Which GPU is faster for gaming right now?

Radeon 620 is the faster gaming card right now. In our data, it leads by 5.4% in average FPS across 50 tracked games in our benchmark data and by 0.8% in PassMark G3D (954 vs 946), so the answer here is pretty clean.

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 40nm and a newer 2019 generation instead of 2012. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Radeon HD 6670/7670 makes the most sense to buy today. It is $1 cheaper on MSRP at $99 vs $100, and it leads G3D-per-dollar by 0.2% (9.6 vs 9.5), which is enough to swing the recommendation its way. If you are mainly targeting 1080p and some 1440p, Radeon HD 6670/7670 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon 620 has the stronger long-term case.
