Quick Answers

Which GPU is faster for gaming right now?

Radeon HD 6990 is the faster gaming card right now. In our data, it leads by 51.8% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Radeon 740M instead at 3,045 vs 3,014, 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 740M is the safer long-term pick for 2026 and beyond. The case is simple: a 4nm process instead of 40nm, 4 vs 0 ray-tracing units, and a newer 2024 generation instead of 2011. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

Radeon HD 6990 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 6990 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon 740M has the stronger long-term case.
