GeForce 6600 vs RADEON X800 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.

GeForce 6600

2012

Why buy it

✅Draws 140W instead of 300W, a 160W reduction.

Trade-offs

❌2012 hardware with 256 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌
8.4% HIGHER MSRP
$270 MSRPvs$249 MSRP

RADEON X800 GT

2020

Why buy it

✅Costs $21 less on MSRP ($249 MSRP vs $270 MSRP).
✅GeForce 6600 is already obsolete for modern gaming, so RADEON X800 GT is the less risky modern option long term.
✅More future proof: RDNA 2.0 (2020−2025) on 7nm with a newer platform for upcoming games.

Trade-offs

❌Older hardware, 256 MB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
❌114.3% higher power demand at 300W vs 140W.

Quick Answers

Which GPU is faster for gaming right now?

GeForce 6600 is the faster gaming card right now based on the synthetic data we have. It leads by 2.4% in PassMark G3D (86 vs 84), which is the best performance signal available in this matchup.

Which GPU is the safer long-term pick for 2026 and beyond?

RADEON X800 GT is the safer long-term pick for 2026 and beyond. The case is simple: the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 7nm process instead of 28nm, 72 vs 0 ray-tracing units, and a newer 2020 generation instead of 2012. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

RADEON X800 GT makes the most sense to buy today. It is $21 cheaper on MSRP at $249 vs $270, and it leads G3D-per-dollar by 5.9% (0.3 vs 0.3), which is enough to swing the recommendation its way. GeForce 6600 still makes more sense if max raw gaming performance matters more than value.
