Mobility Radeon X1700 vs Radeon HD 4270 Performance Spectrum

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.

Mobility Radeon X1700 vs 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.

Mobility Radeon X1700

2010

Why buy it

  • Costs $1 less on MSRP ($49 MSRP vs $50 MSRP).
  • Draws 50W instead of 150W, a 100W reduction.
  • More future proof: TeraScale 2 (2009−2015) on 40nm with a newer platform for upcoming games.

Trade-offs

  • Less VRAM, with 256 MB vs 512 MB for high-resolution textures and newer games.
  • 2010 hardware with 256 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Radeon HD 4270

2008

Why buy it

  • 100% more VRAM for high-resolution textures and newer games (512 MB vs 256 MB).

Trade-offs

  • 2008 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 200% higher power demand at 150W vs 50W.

Quick Answers

Which GPU is faster for gaming right now?
Radeon HD 4270 is the faster gaming card right now based on the synthetic data we have. It leads by 4.8% in PassMark G3D (110 vs 105), which is the best performance signal available in this matchup.
Which GPU is the safer long-term pick for 2026 and beyond?
Mobility Radeon X1700 is the safer long-term pick for 2026 and beyond. The case is simple: a 40nm process instead of 55nm and a newer 2010 generation instead of 2008. That makes it the less risky pick as game demands keep moving.
Which GPU is the better buy today?
Radeon HD 4270 makes the most sense to buy today. It is $1 more expensive on MSRP at $50 vs $49, and it leads G3D-per-dollar by 2.7% (2.2 vs 2.1), so the value case lines up with the gaming result. If you are mainly targeting 1080p and some 1440p, Radeon HD 4270 is the easier value choice. If you care more about 1080p and some 1440p headroom, Mobility Radeon X1700 has the stronger long-term case.
