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.

Iris Graphics 6100 vs Radeon HD 4770: 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 6100

2015

Why buy it

  • Draws 15W instead of 80W, a 65W reduction.
  • More future proof: Generation 8.0 (2014−2015) 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 8.3 G3D/$ (Unknown MSRP vs $109 MSRP).

Radeon HD 4770

2009

Why buy it

  • Delivers 100+% more G3D Mark for each dollar spent, at 8.3 vs 0 G3D/$ ($109 MSRP vs Unknown MSRP).
  • 100+% more VRAM for high-resolution textures and newer games (512 MB vs Unknown).
  • Iris Graphics 6100 is already obsolete for modern gaming, so Radeon HD 4770 is the less risky modern option long term.

Trade-offs

  • 2009 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 433.3% higher power demand at 80W vs 15W.

Quick Answers

Which GPU is faster for gaming right now?
Radeon HD 4770 is the faster gaming card right now based on the synthetic data we have. It leads by 1.1% in PassMark G3D (909 vs 899), which is the best performance signal available in this matchup.
Which GPU is the safer long-term pick for 2026 and beyond?
Radeon HD 4770 is the safer long-term pick for 2026 and beyond. The case is simple: 512 MB 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.
Which GPU is the better buy today?
Radeon HD 4770 makes the most sense today based on the pricing and value data we have for this matchup.
