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 705M vs Mobility Radeon HD 4670: 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 705M

2015

Why buy it

  • ✅More future proof: Maxwell (2014−2017) on 28nm with a newer platform for upcoming games.

Trade-offs

  • ❌Less VRAM, with 512 MB vs 1 GB for high-resolution textures and newer games.
  • ❌2015 hardware with 512 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 6.9 G3D/$ (Unknown MSRP vs $67 MSRP).
  • ❌150% higher power demand at 75W vs 30W.

Mobility Radeon HD 4670

2009

Why buy it

  • ✅Delivers 100+% more G3D Mark for each dollar spent, at 6.9 vs 0 G3D/$ ($67 MSRP vs Unknown MSRP).
  • ✅100% more VRAM for high-resolution textures and newer games (1 GB vs 512 MB).
  • ✅Draws 30W instead of 75W, a 45W reduction.

Trade-offs

  • ❌2009 hardware with 1 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
