GeForce 8400 SE vs GeForce 8400M GT: 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 8400 SE

2014

Why buy it

  • 100% more VRAM for high-resolution textures and newer games (512 MB vs 256 MB).
  • More future proof: Maxwell (2014−2017) on 28nm with a newer platform for upcoming games.

Trade-offs

  • 2014 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

GeForce 8400M GT

2014

Why buy it

  • Competitive enough if your priority is price, power, or specific feature preference.

Trade-offs

  • Less VRAM, with 256 MB vs 512 MB for high-resolution textures and newer games.
  • 2014 hardware with 256 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
