GeForce GT 745A vs Iris Graphics 540: 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 GT 745A
2013Why buy it
- ✅Delivers 100+% more G3D Mark for each dollar spent, at 12.5 vs 0 G3D/$ ($99 MSRP vs Unknown MSRP).
- ✅100+% more VRAM for high-resolution textures and newer games (512 MB vs Unknown).
- ✅Iris Graphics 540 is already obsolete for modern gaming, so GeForce GT 745A 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.
- ❌120% higher power demand at 33W vs 15W.
Iris Graphics 540
2015Why buy it
- ✅Draws 15W instead of 33W, a 18W reduction.
