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
2012Why 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).
