GeForce 8400M GS vs Mobility Radeon HD 3400 Serisi: Pros, Cons & Final Verdict

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

GeForce 8400M GS

2014

Why buy it

  • More future proof: Maxwell (2014−2017) on 28nm with a newer platform for upcoming games.

Trade-offs

  • Less VRAM, with 128 MB vs 512 MB for high-resolution textures and newer games.
  • 2014 hardware with 128 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 2% HIGHER MSRP
    $50 MSRPvs$49 MSRP

Mobility Radeon HD 3400 Serisi

2009

Why buy it

  • Costs $1 less on MSRP ($49 MSRP vs $50 MSRP).
  • 300% more VRAM for high-resolution textures and newer games (512 MB vs 128 MB).
