GeForce GT 640M LE vs NVS 510: 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 $369 less on MSRP ($80 MSRP vs $449 MSRP).
  • Delivers 475.3% more G3D Mark for each dollar spent, at 8.7 vs 1.5 G3D/$ ($80 MSRP vs $449 MSRP).
  • Draws 32W instead of 68W, a 36W reduction.

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.

NVS 510

2015

Why buy it

  • More future proof: Maxwell (2014−2017) on 28nm with a newer platform for upcoming games.

Trade-offs
