GeForce 770M vs Iris Graphics 550: 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 770M
2013Why buy it
- ✅100+% more VRAM for high-resolution textures and newer games (512 MB vs Unknown).
- ✅Iris Graphics 550 is already obsolete for modern gaming, so GeForce 770M is the less risky modern option long term.
Trade-offs
- ❌2013 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 Graphics 550
2015Why buy it
- ✅Draws 15W instead of 75W, a 60W 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 512 MB for high-resolution textures and newer games.
