Radeon HD 8870M vs Seria Radeon HD 7700: 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 8870M

2013

Why buy it

  • 300% more VRAM for high-resolution textures and newer games (2 GB vs 512 MB).
  • Draws 50W instead of 250W, a 200W reduction.
  • More future proof: GCN 1.0 (2012−2020) on 28nm with a newer platform for upcoming games.

Trade-offs

  • 2013 hardware with 2 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 10.1 G3D/$ (Unknown MSRP vs $159 MSRP).

Seria Radeon HD 7700

2012

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 10.1 vs 0 G3D/$ ($159 MSRP vs Unknown MSRP).

Trade-offs

  • Less VRAM, with 512 MB vs 2 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.
  • 400% higher power demand at 250W vs 50W.
