GeForce FX 5900ZT vs MOBILITY RADEON X300: 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 FX 5900ZT

2011

Why buy it

  • More future proof: Fermi 2.0 (2010−2014) on 40nm with a newer platform for upcoming games.

Trade-offs

  • 2011 hardware with 128 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • Lower G3D Mark per dollar, at 0 vs 0.7 G3D/$ (Unknown MSRP vs $50 MSRP).
  • 630% higher power demand at 365W vs 50W.

MOBILITY RADEON X300

2010

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 0.7 vs 0 G3D/$ ($50 MSRP vs Unknown MSRP).
  • Draws 50W instead of 365W, a 315W reduction.
