GeForce GTX 680M vs Radeon HD 6990M: Pros, Cons & Final Verdict

See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

GeForce GTX 680M

2012

Why buy it

  • 1.5% more average FPS across 50 tracked games in our benchmark data.
  • 100% more VRAM for high-resolution textures and newer games (4 GB vs 2 GB).
  • More future proof: Kepler (2012−2018) on 28nm with a newer platform for upcoming games.

Trade-offs

  • 2012 hardware with 4 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Radeon HD 6990M

2011

Why buy it

  • Competitive enough if your priority is price, power, or specific feature preference.

Trade-offs

  • Lower average FPS than GeForce GTX 680M across 50 tracked games in our benchmark data.
  • Less VRAM, with 2 GB vs 4 GB for high-resolution textures and newer games.
  • 2011 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Quick Answers

Which GPU is faster for gaming right now?
GeForce GTX 680M is the faster gaming card right now. In our data, it leads by 1.5% in average FPS across 50 tracked games in our benchmark data and by 0.4% in PassMark G3D (3,277 vs 3,264), so the answer here is pretty clean.
Which GPU is the safer long-term pick for 2026 and beyond?
GeForce GTX 680M is the safer long-term pick for 2026 and beyond. The case is simple: 4 GB vs 2 GB of VRAM, a 28nm process instead of 40nm, and a newer 2012 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 GTX 680M makes the most sense today based on the pricing and value data we have for this matchup.
