title: Approximate Number of CPU Cycles for Various Operations
body: <p>I am trying to find a reference for approximately how many CPU cycles various operations require.</p>
  
  <p>I don't need exact numbers (as this is going to vary between CPUs) but I'd like something relatively credible that gives ballpark figures that I could cite in discussion with friends.</p>
  
  <p>As an example, we all know that floating point division takes more CPU cycles than say doing a bitshift. </p>
  
  <p>I'd guess that the difference is that the division is around 100 cycles, where as a shift is 1 but I'm looking for something to cite to back that up.</p>
  
  <p>Can anyone recommend such a resource?</p>
