GeForce GT 750M vs Iris Plus Graphics 640: 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 GT 750M

2013

Why buy it

  • 100+% more VRAM for high-resolution textures and newer games (2 GB vs Unknown).
  • Iris Plus Graphics 640 is already obsolete for modern gaming, so GeForce GT 750M is the less risky modern option long term.

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.
  • 233.3% higher power demand at 50W vs 15W.

Iris Plus Graphics 640

2017

Why buy it

  • Draws 15W instead of 50W, a 35W reduction.
  • More future proof: Generation 9.5 (2016−2020) on 14nm with a newer platform for upcoming games.

Trade-offs

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