Intel Processor Events Reference

Intel® VTune™
Profiler
provides a set of hardware event-based analysis types that help you estimate how effectively your application uses hardware resources. These analysis types monitor hardware events supported by your system's
Performance Monitoring Unit (PMU)
. The PMU is hardware built inside a processor to measure its performance parameters such as instruction cycles, cache hits, cache misses, branch misses and many others.
For more information on Intel® 64 and IA-32 architectures, explore
Intel Software Developer Manuals
available at https://software.intel.com/en-us/articles/intel-sdm.
For details on hardware events supported by your system's PMU, use any of the following options:

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
