Mobility Radeon HD 4670 vs Radeon R5 M320: Pros, Cons & Final Verdict

See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

Mobility Radeon HD 4670

2009

Why buy it

  • Costs $83 less on MSRP ($67 MSRP vs $150 MSRP).
  • Delivers 118.2% more G3D Mark for each dollar spent, at 6.9 vs 3.2 G3D/$ ($67 MSRP vs $150 MSRP).
  • 100% more VRAM for high-resolution textures and newer games (1 GB vs 512 MB).
  • Draws 30W instead of 75W, a 45W reduction.

Trade-offs

  • 2009 hardware with 1 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Radeon R5 M320

2015

Why buy it

  • More future proof: GCN (2012−2015) on 28nm with a newer platform for upcoming games.

Trade-offs

  • Less VRAM, with 512 MB vs 1 GB for high-resolution textures and newer games.
