Iris Graphics 540 vs Radeon HD 8670D + HD 6670 Dual: Pros, Cons & Final Verdict

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

Iris Graphics 540

2015

Why buy it

  • Draws 15W instead of 50W, a 35W reduction.
  • More future proof: Generation 9.0 (2015−2016) on 14nm with a newer platform for upcoming games.

Trade-offs

  • Less VRAM, with Unknown vs 512 MB for high-resolution textures and newer games.
  • 2015 hardware with Unknown 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 12.2 G3D/$ (Unknown MSRP vs $100 MSRP).

Radeon HD 8670D + HD 6670 Dual

2013

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 12.2 vs 0 G3D/$ ($100 MSRP vs Unknown MSRP).
  • 100+% more VRAM for high-resolution textures and newer games (512 MB vs Unknown).
  • Iris Graphics 540 is already obsolete for modern gaming, so Radeon HD 8670D + HD 6670 Dual is the less risky modern option long term.

Trade-offs

  • 2013 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 233.3% higher power demand at 50W vs 15W.
