Radeon HD 6480M vs Radeon HD 6620G: 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 6480M

2010

Why buy it

  • 48.9% more average FPS across 50 tracked games in our benchmark data.

Trade-offs

  • 2010 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 6.8 G3D/$ (Unknown MSRP vs $50 MSRP).
  • 235.6% higher power demand at 151W vs 45W.

Radeon HD 6620G

2011

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 6.8 vs 0 G3D/$ ($50 MSRP vs Unknown MSRP).
  • Draws 45W instead of 151W, a 106W reduction.
  • More future proof: TeraScale 2 (2009−2015) on 40nm with a newer platform for upcoming games.

Trade-offs

  • Lower average FPS than Radeon HD 6480M across 50 tracked games in our benchmark data.
  • 2011 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
