title: What ARM Floating Point Performance Comparison across the product line A9, A12, A15, A17, A53 etc
body: <p>I've been research the relative performance of ARM parts, and have found it difficult to come up with comparisons... especially for the new A12, A17 and the 64 bit A53 an A57s;</p>
  
  <p>What I've come up with so far, based on Linpack scores of different phone/tablets is this:</p>
  
  <ul>
  <li>A9 = 32 MFLOPS/Core/GHz </li>
  <li>A15 = 100 MFLOPS/Core/GHz </li>
  <li>Apple A7 = 350 MFLOPS /Core/GHz (!)</li>
  </ul>
  
  <p>So a couple questions arise:</p>
  
  <ol>
  <li>Where does the A12, A17, A53, A57 fit into this spectrum</li>
  <li>Why is Apple's A7 floating point so good? It is purely due to the 64bit internals, or something else?</li>
  </ol>
