Intel® Xeon Phi™ Processor

Access a unique combination of the following performance monitoring capabilities:

  • Core performance monitoring units (PMU) in the Intel Atom® processor 
  • Server-class uncore capabilities that are based on the Intel® Xeon® processor

Many programs written for the Intel Xeon processor also run on the Intel® Xeon Phi™ processor. Programs that make calls directly to a vector-intrinsic programming model may require the most changes.
