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.

GRID M6-1Q vs Iris Pro Graphics P580: Pros, Cons & Final Verdict

See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

GRID M6-1Q

2015

Why buy it

  • ✅100+% more VRAM for high-resolution textures and newer games (2 GB vs Unknown).
  • ✅Iris Pro Graphics P580 is already obsolete for modern gaming, so GRID M6-1Q is the less risky modern option long term.

Trade-offs

  • ❌2015 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • ❌
    900% HIGHER MSRP
    $1,500 MSRPvs$150 MSRP
  • ❌Lower G3D Mark per dollar, at 1.4 vs 13.5 G3D/$ ($1,500 MSRP vs $150 MSRP).
  • ❌1400% higher power demand at 225W vs 15W.

Iris Pro Graphics P580

2015

Why buy it

  • ✅Costs $1,350 less on MSRP ($150 MSRP vs $1,500 MSRP).
  • ✅Delivers 879.2% more G3D Mark for each dollar spent, at 13.5 vs 1.4 G3D/$ ($150 MSRP vs $1,500 MSRP).
  • ✅Draws 15W instead of 225W, a 210W reduction.

Trade-offs

  • ❌Less VRAM, with Unknown vs 2 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.

Quick Answers
