GeForce GTX 285 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 285

2008

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 4.1 vs 0 G3D/$ ($359 MSRP vs Unknown MSRP).
  • 100+% more VRAM for high-resolution textures and newer games (1 GB vs Unknown).
  • Iris Plus Graphics 645 is already obsolete for modern gaming, so GeForce GTX 285 is the less risky modern option long term.

Trade-offs

  • 2008 hardware with 1 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 1260% higher power demand at 204W vs 15W.

Iris Plus Graphics 645

2019

Why buy it

  • Draws 15W instead of 204W, a 189W reduction.
