Quick Answers

Which GPU is faster for gaming right now?

GeForce 820M is the faster gaming card right now. In our data, it leads by 419.6% in average FPS across 16 tracked games in our benchmark data and by 0.2% in PassMark G3D (482 vs 481), so the answer here is pretty clean.

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

GeForce 820M is the safer long-term pick for 2026 and beyond. The case is simple: 2 GB vs 512 MB of VRAM, a 28nm process instead of 40nm, and a newer 2014 generation instead of 2012. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon HD 7660G 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, Radeon HD 7660G is the easier value choice. If you care more about 1080p and some 1440p headroom, GeForce 820M has the stronger long-term case.
