GRID K120Q vs Radeon HD 2900 GT 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.

GRID K120Q vs Radeon HD 2900 GT: Pros, Cons & Final Verdict

See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

GRID K120Q

2013

Why buy it

  • Costs $45 less on MSRP ($125 MSRP vs $170 MSRP).
  • Delivers 36.5% more G3D Mark for each dollar spent, at 2.3 vs 1.7 G3D/$ ($125 MSRP vs $170 MSRP).
  • More future proof: Kepler (2012−2018) on 28nm with a newer platform for upcoming games.

Trade-offs

  • 2013 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 800% higher power demand at 225W vs 25W.

Radeon HD 2900 GT

2013

Why buy it

  • Draws 25W instead of 225W, a 200W reduction.
