Radeon R5 M330 vs Radeon R6 M255DX: 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 R5 M330

2015

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 5.0 vs 0 G3D/$ ($120 MSRP vs Unknown MSRP).
  • 700% more VRAM for high-resolution textures and newer games (4 GB vs 512 MB).
  • More future proof: GCN (2012−2015) on 28nm with a newer platform for upcoming games.

Trade-offs

  • Lower average FPS than Radeon R6 M255DX across 50 tracked games in our benchmark data.
  • 2015 hardware with 4 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 150% higher power demand at 75W vs 30W.

Radeon R6 M255DX

2014

Why buy it

  • 6.5% more average FPS across 50 tracked games in our benchmark data.
  • Draws 30W instead of 75W, a 45W reduction.

Trade-offs

  • Less VRAM, with 512 MB vs 4 GB for high-resolution textures and newer games.
  • 2014 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
