Mobility Radeon HD 5165 vs Radeon HD 8400: 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 5165

2010

Why buy it

  • 100% more VRAM for high-resolution textures and newer games (1 GB vs 512 MB).
  • Draws 50W instead of 200W, a 150W reduction.

Trade-offs

  • 2010 hardware with 1 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 63.3% HIGHER MSRP
    $49 MSRPvs$30 MSRP
  • Lower G3D Mark per dollar, at 5.8 vs 9.0 G3D/$ ($49 MSRP vs $30 MSRP).

Radeon HD 8400

2012

Why buy it

  • Costs $19 less on MSRP ($30 MSRP vs $49 MSRP).
  • Delivers 55.9% more G3D Mark for each dollar spent, at 9.0 vs 5.8 G3D/$ ($30 MSRP vs $49 MSRP).
  • More future proof: GCN 1.0 (2012−2020) 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.
  • 2012 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 300% higher power demand at 200W vs 50W.
