Radeon HD 6430M vs Radeon HD 6450: Pros, Cons & Final Verdict

See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

Radeon HD 6430M

2011

Why buy it

  • 100% more VRAM for high-resolution textures and newer games (1 GB vs 512 MB).
  • More future proof: TeraScale 3 (2010−2013) on 40nm with a newer platform for upcoming games.

Trade-offs

  • 2011 hardware with 1 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 3.6 G3D/$ (Unknown MSRP vs $55 MSRP).

Radeon HD 6450

2010

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 3.6 vs 0 G3D/$ ($55 MSRP vs Unknown MSRP).

Trade-offs

  • Less VRAM, with 512 MB vs 1 GB for high-resolution textures and newer games.
  • 2010 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
