GeForce GTX 670MX vs Iris Pro Graphics 580 Performance Spectrum

About G3D Mark

G3D Mark is a standard benchmark that measures graphics performance in real-world gaming scenarios. It simplifies comparing cards from different brands, where higher scores directly correlate with better fps and smoother gaming experiences.

GeForce GTX 670MX vs Iris Pro Graphics 580: 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 670MX

2012

Why buy it

  • 100+% more VRAM for high-resolution textures and newer games (3 GB vs Unknown).
  • Iris Pro Graphics 580 is already obsolete for modern gaming, so GeForce GTX 670MX is the less risky modern option long term.

Trade-offs

  • 2012 hardware with 3 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 66.7% higher power demand at 75W vs 45W.

Iris Pro Graphics 580

2015

Why buy it

  • Draws 45W instead of 75W, a 30W reduction.
  • More future proof: Generation 9.0 (2015−2016) on 14nm with a newer platform for upcoming games.

Trade-offs

  • Less VRAM, with Unknown vs 3 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.
