GeForce GTS 450 vs Iris Plus Graphics 640 Performance Spectrum

About G3D Mark

G3D Mark is a standard benchmark that measures graphics performance in real-world gaming scenarios. It simplifies comparing cards from different brands, where higher scores directly correlate with better fps and smoother gaming experiences.

GeForce GTS 450 vs Iris Plus Graphics 640: 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 GTS 450

2010

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 10.4 vs 0 G3D/$ ($129 MSRP vs Unknown MSRP).
  • 100+% more VRAM for high-resolution textures and newer games (1 GB vs Unknown).
  • Iris Plus Graphics 640 is already obsolete for modern gaming, so GeForce GTS 450 is the less risky modern option long term.

Trade-offs

  • 2010 hardware with 1 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 606.7% higher power demand at 106W vs 15W.

Iris Plus Graphics 640

2017

Why buy it

  • Draws 15W instead of 106W, a 91W 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 1 GB for high-resolution textures and newer games.
  • 2017 hardware with Unknown of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • Lower G3D Mark per dollar, at 0 vs 10.4 G3D/$ (Unknown MSRP vs $129 MSRP).
