GeForce GTX 580M SLI vs Iris Plus Graphics 950: 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 580M SLI

2011

Why buy it

✅100+% more VRAM for high-resolution textures and newer games (512 MB vs Unknown).
✅Iris Plus Graphics 950 is already obsolete for modern gaming, so GeForce GTX 580M SLI is the less risky modern option long term.
✅More future proof: Fermi (2010−2014) on 40nm with a newer platform for upcoming games.

Trade-offs

❌2011 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌566.7% higher power demand at 100W vs 15W.

Iris Plus Graphics 950

Why buy it

✅Draws 15W instead of 100W, a 85W reduction.

Trade-offs

❌Less VRAM, with Unknown vs 512 MB for high-resolution textures and newer games.
❌Older hardware with Unknown of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Quick Answers

Which GPU is faster for gaming right now?

Iris Plus Graphics 950 is the faster gaming card right now based on the synthetic data we have. It leads by 1% in PassMark G3D (1,789 vs 1,771), which is the best performance signal available in this matchup.

Which GPU is the safer long-term pick for 2026 and beyond?

GeForce GTX 580M SLI is the safer long-term pick for 2026 and beyond. The case is simple: 512 MB vs Unknown of VRAM and a newer 2011 generation instead of 0. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Iris Plus Graphics 950 makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p, Iris Plus Graphics 950 is the easier value choice.
