GeForce 705M vs Radeon HD 7640G: 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 705M

2015

Why buy it

  • 41.9% more average FPS across 50 tracked games in our benchmark data.
  • More future proof: Maxwell (2014−2017) on 28nm with a newer platform for upcoming games.

Trade-offs

  • 2015 hardware with 512 MB 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 9.1 G3D/$ (Unknown MSRP vs $50 MSRP).
  • 66.7% higher power demand at 75W vs 45W.

Radeon HD 7640G

2012

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 9.1 vs 0 G3D/$ ($50 MSRP vs Unknown MSRP).
  • Draws 45W instead of 75W, a 30W reduction.

Trade-offs

  • Lower average FPS than GeForce 705M across 50 tracked games in our benchmark data.
  • 2012 hardware with 512 MB 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 705M is the faster gaming card right now. In our data, it leads by 41.9% in average FPS across 50 tracked games in our benchmark data and by 0.4% in PassMark G3D (456 vs 454), so the answer here is pretty clean.
Which GPU is the safer long-term pick for 2026 and beyond?
GeForce 705M is the safer long-term pick for 2026 and beyond. The case is simple: a 28nm process instead of 40nm and a newer 2015 generation instead of 2012. That makes it the less risky pick as game demands keep moving.
Which GPU is the better buy today?
Radeon HD 7640G 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 7640G is the easier value choice. If you care more about 1080p and some 1440p headroom, GeForce 705M has the stronger long-term case.
