title: Benchmarks comparing Intel Xeon Phi and Nvidia Tesla K20
body: <p>To my surprise, I cannot find a comparison of these products using open source OpenCL benchmark suites, such as <a href="https://www.cs.virginia.edu/~skadron/wiki/rodinia/index.php/Main_Page" rel="nofollow">rodinia</a> and <a href="https://github.com/spaffy/shoc/wiki" rel="nofollow">SHOC</a>. Such a comparison could be more interesting than comparisons of theoretical peak performance, or of performance in simple matrix multiplication kernels, which I have been able to find.</p>
  
  <p>Does anyone know where such results might be available? Failing that, do any stack overflow users have access to one or both products, and the time and inclination to run the benchmarks and share the results? Results for any of the versions of either card would be interesting.</p>
