Radeon HD 7550M 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.

Radeon HD 7550M

2012

Why buy it

  • 18.2% more average FPS across 50 tracked games in our benchmark data.
  • 100% more VRAM for high-resolution textures and newer games (1 GB vs 512 MB).
  • More future proof: GCN 1.0 (2012−2020) on 28nm with a newer platform for upcoming games.

Trade-offs

  • 2012 hardware with 1 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 9.1 G3D/$ (Unknown MSRP vs $50 MSRP).

Radeon HD 7640G

2012

Why buy it

Trade-offs

  • Lower average FPS than Radeon HD 7550M across 50 tracked games in our benchmark data.
  • Less VRAM, with 512 MB vs 1 GB for high-resolution textures and newer games.
  • 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?
Radeon HD 7550M is the faster gaming card right now. In our data, it leads by 18.2% in average FPS across 50 tracked games in our benchmark data and by 2.4% in PassMark G3D (465 vs 454), so the answer here is pretty clean.
Which GPU is the safer long-term pick for 2026 and beyond?
Radeon HD 7550M is the safer long-term pick for 2026 and beyond. The case is simple: 1 GB vs 512 MB of VRAM and a 28nm process instead of 40nm. That gives it more room for heavier textures and higher settings over time.
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, Radeon HD 7550M has the stronger long-term case.
