&gt; There are more computers on the Top 500 supercomputer list using AMD GPUs than Nvidia GPUs.<p>I&#x27;d like to see numbers on that.<p>CUDA hits in Google: 24,000,000
OpenCL hits in Google: 1,000,000<p>I tried to use OpenCL a number of years ago and the drivers were brutal.  CUDA just works.<p>The number of great libraries available for CUDA is huge, where as the OpenCL ecosystem is more expensive to participate in because those fundamental libraries are not available.<p>You will get more bang for your buck doing CUDA on Windows or Linux than OpenCL.
