Hardware Event Sample Count

Hardware Event Sample Count is a performance metric used by the
Intel® VTune™
Profiler
 when interpreting event-based sampling analysis results. The Hardware Event Sample Count metric shows the sample count for all collected processor events. While the Hardware Event Count metric estimates the number of times an event occurred during the analysis, the Hardware Sample Count metric provides the actual number of samples collected for this event.
To view the Hardware Event Sample Count data, choose the Hardware Events viewpoint and click the Sample Count tab.

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.
