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 320.5% in average FPS across 18 tracked games in our benchmark data. PassMark G3D leans toward Radeon R4E instead at 487 vs 482, 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?

GeForce 820M is the safer long-term pick for 2026 and beyond. The case is simple: 2 GB vs 512 MB of VRAM. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon R4E 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 R4E is the easier value choice. If you care more about 1080p and some 1440p headroom, GeForce 820M has the stronger long-term case.
