Cache Miss Rates in Intel® VTune™ Amplifier XE

Intel® VTune™ Amplifier XE has the ability to use Performance Monitoring Units (PMUs) on Intel CPUs to count hardware events and use these events to locate performance issues. The most common way to do this is through the General Exploration analysis type. One set of metrics within General Exploration is related to the memory subsystem and can be found in the Back-End Bound > Memory Bound section of the hierarchy. A common question we receive about memory metrics is "can I calculate cache hit and miss rates?".
