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 GT 640 vs Iris Pro Graphics 5200: 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 640

2012

Why buy it

  • ✅Costs $51 less on MSRP ($99 MSRP vs $150 MSRP).
  • ✅Delivers 51.1% more G3D Mark for each dollar spent, at 11.8 vs 7.8 G3D/$ ($99 MSRP vs $150 MSRP).
  • ✅100+% more VRAM for high-resolution textures and newer games (4 GB vs Unknown).
  • ✅Iris Pro Graphics 5200 is already obsolete for modern gaming, so GeForce GT 640 is the less risky modern option long term.

Trade-offs

  • ❌2012 hardware with 4 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • ❌116.7% higher power demand at 65W vs 30W.

Iris Pro Graphics 5200

2013

Why buy it

  • ✅Draws 30W instead of 65W, a 35W reduction.
