GeForce GTX 680M KY_Bullet Edition vs GRID K520 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 GTX 680M KY_Bullet Edition vs GRID K520: 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 680M KY_Bullet Edition

2013

Why buy it

  • Draws 122W instead of 225W, a 103W reduction.
  • Measures 105mm instead of 267mm, a 162mm shorter card that is more SFF-friendly.

Trade-offs

  • 2013 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
