Iris Pro Graphics P580 vs Quadro P520 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.

Iris Pro Graphics P580 vs Quadro P520: Pros, Cons & Final Verdict

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

Iris Pro Graphics P580

2015

Why buy it

  • Draws 15W instead of 18W, a 3W 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.

Quadro P520

2019

Why buy it

  • 100+% more VRAM for high-resolution textures and newer games (4 GB vs Unknown).
  • Iris Pro Graphics P580 is already obsolete for modern gaming, so Quadro P520 is the less risky modern option long term.
  • More future proof: Pascal (2016−2021) on 14nm with a newer platform for upcoming games.

Trade-offs

  • 2019 hardware with 4 GB of VRAM already sits in legacy territory for modern games.
  • 20% higher power demand at 18W vs 15W.

Quick Answers

Which GPU is faster for gaming right now?
Quadro P520 is the faster gaming card right now based on the synthetic data we have. It leads by 0.4% in PassMark G3D (2,034 vs 2,026), which is the best performance signal available in this matchup.
Which GPU is the safer long-term pick for 2026 and beyond?
Quadro P520 is the safer long-term pick for 2026 and beyond. The case is simple: 4 GB vs Unknown of VRAM and a newer 2019 generation instead of 2015. That gives it more room for heavier textures and higher settings over time.
Which GPU is the better buy today?
Quadro P520 makes the most sense to buy today. It is priced the same on MSRP at $150 vs $150, and it leads G3D-per-dollar by 0.4% (13.6 vs 13.5), so the value case lines up with the gaming result.
