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 640M LE vs Intel UHD Graphics 615: 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 640M LE

2012

Why buy it

  • ✅Costs $20 less on MSRP ($80 MSRP vs $100 MSRP).
  • ✅Delivers 21.5% more G3D Mark for each dollar spent, at 8.7 vs 7.2 G3D/$ ($80 MSRP vs $100 MSRP).
  • ✅100+% more VRAM for high-resolution textures and newer games (2 GB vs Unknown).
  • ✅Intel UHD Graphics 615 is already obsolete for modern gaming, so GeForce GT 640M LE is the less risky modern option long term.

Trade-offs

  • ❌2012 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • ❌113.3% higher power demand at 32W vs 15W.

Intel UHD Graphics 615

2018

Why buy it
