GeForce GT 705 vs Mobility Radeon HD 3850: 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 GT 705

2014

Why buy it

  • Costs $90 less on MSRP ($60 MSRP vs $150 MSRP).
  • Delivers 152.7% more G3D Mark for each dollar spent, at 6.2 vs 2.4 G3D/$ ($60 MSRP vs $150 MSRP).
  • 100% more VRAM for high-resolution textures and newer games (1 GB vs 512 MB).

Trade-offs

  • 2014 hardware with 1 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 28% higher power demand at 64W vs 50W.
