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 6600 vs Mobility Radeon HD 4270: 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 6600

2012

Why buy it

  • More future proof: Kepler (2012−2018) on 28nm with a newer platform for upcoming games.

Trade-offs

  • Lower PassMark G3D performance (86 vs 93).
  • Less VRAM, with 256 MB vs 512 MB for high-resolution textures and newer games.
  • 2012 hardware with 256 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 451% HIGHER MSRP
    $270 MSRPvs$49 MSRP
  • Lower G3D Mark per dollar, at 0.3 vs 1.9 G3D/$ ($270 MSRP vs $49 MSRP).

Mobility Radeon HD 4270

2009

Why buy it

  • +8.1% higher PassMark G3D performance.
  • Costs $221 less on MSRP ($49 MSRP vs $270 MSRP).
  • Delivers 495.9% more G3D Mark for each dollar spent, at 1.9 vs 0.3 G3D/$ ($49 MSRP vs $270 MSRP).
  • 100% more VRAM for high-resolution textures and newer games (512 MB vs 256 MB).
  • Draws 30W instead of 140W, a 110W reduction.

Trade-offs

  • 2009 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Quick Answers

Which GPU is faster for gaming right now?
Mobility Radeon HD 4270 is the faster gaming card right now based on the synthetic data we have. It leads by 8.1% in PassMark G3D (93 vs 86), which is the best performance signal available in this matchup.
Which GPU is the safer long-term pick for 2026 and beyond?
GeForce 6600 is the safer long-term pick for 2026 and beyond. The case is simple: a 28nm process instead of 55nm and a newer 2012 generation instead of 2009. That makes it the less risky pick as game demands keep moving.
Which GPU is the better buy today?
Mobility Radeon HD 4270 makes the most sense to buy today. It is $221 cheaper on MSRP at $49 vs $270, and it leads G3D-per-dollar by 495.9% (1.9 vs 0.3), so the value case lines up with the gaming result. If you are mainly targeting 1080p and some 1440p, Mobility Radeon HD 4270 is the easier value choice. If you care more about 1080p and some 1440p headroom, GeForce 6600 has the stronger long-term case.
