Iris Graphics 540 vs Radeon HD 6770: 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 108W, a 93W 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 1 GB 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 9.9 G3D/$ (Unknown MSRP vs $129 MSRP).

Radeon HD 6770

2011

Why buy it

  • ✅Delivers 100+% more G3D Mark for each dollar spent, at 9.9 vs 0 G3D/$ ($129 MSRP vs Unknown MSRP).
  • ✅100+% more VRAM for high-resolution textures and newer games (1 GB vs Unknown).
  • ✅Iris Graphics 540 is already obsolete for modern gaming, so Radeon HD 6770 is the less risky modern option long term.

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.
  • ❌620% higher power demand at 108W vs 15W.

Quick Answers

Which GPU is faster for gaming right now?
Radeon HD 6770 is the faster gaming card right now based on the synthetic data we have. It leads by 0.1% in PassMark G3D (1,271 vs 1,270), which is the best performance signal available in this matchup.
Which GPU is the safer long-term pick for 2026 and beyond?
Radeon HD 6770 is the safer long-term pick for 2026 and beyond. The case is simple: 1 GB vs Unknown of VRAM and the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack. That gives it more room for heavier textures and higher settings over time.
