GeForce GTX 960M vs Iris Graphics 550: 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 960M

2015

Why buy it

  • 100+% more VRAM for high-resolution textures and newer games (4 GB vs Unknown).
  • Iris Graphics 550 is already obsolete for modern gaming, so GeForce GTX 960M is the less risky modern option long term.

Trade-offs

  • 2015 hardware with 4 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 400% higher power demand at 75W vs 15W.

Iris Graphics 550

2015

Why buy it

  • Draws 15W instead of 75W, a 60W reduction.

Trade-offs

  • Less VRAM, with Unknown vs 4 GB for high-resolution textures and newer games.
  • 2015 hardware with Unknown of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
