GeForce GT 630M vs Mobility Radeon HD 4830 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.

GeForce GT 630M vs Mobility Radeon HD 4830: 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 630M

2012

Why buy it

  • 100% more VRAM for high-resolution textures and newer games (2 GB vs 1 GB).
  • More future proof: Kepler (2012−2018) on 28nm with a newer platform for upcoming games.

Trade-offs

  • 2012 hardware with 2 GB 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 3.9 G3D/$ (Unknown MSRP vs $130 MSRP).
  • 50% higher power demand at 45W vs 30W.

Mobility Radeon HD 4830

2009

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 3.9 vs 0 G3D/$ ($130 MSRP vs Unknown MSRP).
  • Draws 30W instead of 45W, a 15W reduction.

Trade-offs

  • Less VRAM, with 1 GB vs 2 GB for high-resolution textures and newer games.
  • 2009 hardware with 1 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Quick Answers

Which GPU is faster for gaming right now?
GeForce GT 630M is the faster gaming card right now based on the synthetic data we have. It leads by 1.8% in PassMark G3D (521 vs 512), which is the best performance signal available in this matchup.
Which GPU is the safer long-term pick for 2026 and beyond?
GeForce GT 630M is the safer long-term pick for 2026 and beyond. The case is simple: 2 GB vs 1 GB of VRAM, a 28nm process instead of 55nm, and a newer 2012 generation instead of 2009. That gives it more room for heavier textures and higher settings over time.
Which GPU is the better buy today?
Mobility Radeon HD 4830 makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p and some 1440p, Mobility Radeon HD 4830 is the easier value choice. If you care more about 1080p and some 1440p headroom, GeForce GT 630M has the stronger long-term case.
