GeForce GTX 460M SLI vs Iris Plus Graphics 645: 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 460M SLI
2010Why buy it
- ✅100+% more VRAM for high-resolution textures and newer games (512 MB vs Unknown).
- ✅Iris Plus Graphics 645 is already obsolete for modern gaming, so GeForce GTX 460M SLI is the less risky modern option long term.
Trade-offs
- ❌2010 hardware with 512 MB 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 Plus Graphics 645
2019Why buy it
- ✅Draws 15W instead of 75W, a 60W reduction.
- ✅More future proof: Generation 9.5 (2016−2020) on 14nm with a newer platform for upcoming games.
Trade-offs
- ❌Less VRAM, with Unknown vs 512 MB for high-resolution textures and newer games.
