GeForce GTX 680M SLI vs Radeon HD 6990M Crossfire: 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 SLI

2012

Why buy it

  • 12.7% more average FPS across 50 tracked games in our benchmark data.
  • More future proof: Kepler (2012−2018) on 28nm with a newer platform for upcoming games.

Trade-offs

  • 2012 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • Lower G3D Mark per dollar, at 0 vs 5.0 G3D/$ (Unknown MSRP vs $699 MSRP).
  • 50% higher power demand at 75W vs 50W.

Radeon HD 6990M Crossfire

2011

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 5.0 vs 0 G3D/$ ($699 MSRP vs Unknown MSRP).
  • Draws 50W instead of 75W, a 25W reduction.

Trade-offs

  • Lower average FPS than GeForce GTX 680M SLI across 50 tracked games in our benchmark data.
  • 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 SLI is the faster gaming card right now. In our data, it leads by 12.7% in average FPS across 50 tracked games in our benchmark data and by 2% in PassMark G3D (3,569 vs 3,500), so the answer here is pretty clean.
Which GPU is the safer long-term pick for 2026 and beyond?
GeForce GTX 680M SLI is the safer long-term pick for 2026 and beyond. The case is simple: a 28nm process instead of 40nm and a newer 2012 generation instead of 2011. That makes it the less risky pick as game demands keep moving.
Which GPU is the better buy today?
Radeon HD 6990M Crossfire 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 6990M Crossfire is the easier value choice. If you care more about 1080p and some 1440p headroom, GeForce GTX 680M SLI has the stronger long-term case.
