Intel does not think you need a GPU for HPC
 

Nvidia might have scored a few wins by touting its GPU’s in the HPC market, but it is starting to lose ground to the co-processor, according to Intel’s Diane Bryant.

In an IDC interview Intel’s data centre boss said that Nvidia gained an early lead in the market for accelerated HPC workloads when it positioned its GPUs for that task several years ago. However there is a perception that processors used for machine learning today are GPUs like those from Nvidia and AMD.
