GeForce GTX 680MX vs P104-100: 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 GTX 680MX

2012

Why buy it

  • 100% more VRAM for high-resolution textures and newer games (4 GB vs 2 GB).

Trade-offs

  • 2012 hardware with 4 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 306.7% higher power demand at 122W vs 30W.

P104-100

2017

Why buy it

  • Draws 30W instead of 122W, a 92W reduction.
  • More future proof: Pascal (2016−2021) on 16nm with a newer platform for upcoming games.

Trade-offs

  • Less VRAM, with 2 GB vs 4 GB for high-resolution textures and newer games.
  • 2017 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
