title: Why can Compute Shaders be used to enhance performance?
body: <p>I'm currently researching compute shaders. It is said, that under certain circumstances compute shaders can produce vastly <em>faster</em> rendering results than the standard (say OpenGL) hardware pipeline.</p>
  <p>I understand that it has something to do with work groups and work group invocations and as such with thread utilization and parallel computation.</p>
  <p>But I still haven't come across a good source that explains the parallels and differences between the standard rendering pipeline and compute pipeline in terms of actual performance.</p>
  <p>Any help is appreciated :)</p>
