GeForce 770M 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 770M

2013

Why buy it

✅Draws 75W instead of 100W, a 25W reduction.
✅More future proof: Kepler (2012−2018) on 28nm with a newer platform for upcoming games.

Trade-offs

❌Lower average FPS than Radeon HD 6990M across 50 tracked games in our benchmark data.
❌Less VRAM, with 512 MB vs 2 GB for high-resolution textures and newer games.
❌2013 hardware with 512 MB 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

✅47.3% more average FPS across 50 tracked games in our benchmark data.
✅300% more VRAM for high-resolution textures and newer games (2 GB vs 512 MB).

Trade-offs

❌2011 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌33.3% higher power demand at 100W vs 75W.

Quick Answers

Which GPU is faster for gaming right now?

Radeon HD 6990M is the faster gaming card right now. In our data, it leads by 47.3% in average FPS across 50 tracked games in our benchmark data and by 0.6% in PassMark G3D (3,264 vs 3,246), so the answer here is pretty clean.

Which GPU is the safer long-term pick for 2026 and beyond?

GeForce 770M is the safer long-term pick for 2026 and beyond. The case is simple: a 28nm process instead of 40nm and a newer 2013 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 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 is the easier value choice. If you care more about 1080p and some 1440p headroom, GeForce 770M has the stronger long-term case.
