title: Looking for a research: PNG Sprite vs SVG sprite vs Icon fonts
body: <p>We are currently using PNGs in production for icons, but as a designer I'm trying to push for using SVG's for the benefit of:<br>
  a. Rendering on Retina.<br>
  b. Visually impaired users that zoom in.<br>
  c. An easier workflow when creating icons.  </p>
  
  <p>Are there any researches that compares the 3 methods? (PNG Sprite vs SVG sprite vs Icon fonts) in terms of performance? </p>
  
  <p>If not, what and how would you compare them? (For example, I heard SVG requires more CPU power, and I have no idea how to test it or what are the consequences).</p>
  
  <p>Thanks a lot! You are an amazing community.</p>
  
  <p>BTW, this is what I could find:<br>
