2011

Why buy it

✅91.4% more average FPS across 50 tracked games in our benchmark data.

Trade-offs

❌Less VRAM, with 512 MB vs 2 GB for high-resolution textures and newer games.
❌2011 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌50% higher power demand at 75W vs 50W.

Quick Answers

Which GPU is faster for gaming right now?

Radeon HD 6900M is the faster gaming card right now. In our data, it leads by 91.4% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward GeForce GT 755M instead at 1,726 vs 1,707, 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 GT 755M 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 2013 generation instead of 2011. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

GeForce GT 755M makes the most sense today based on the pricing and value data we have for this matchup. Radeon HD 6900M still makes more sense if max raw gaming performance matters more than value.
