Cycles of 2 Ports Utilized

Metric Description

This metric represents cycles fraction CPU executed total of 2 uops per cycle on all execution ports. Tip: Loop Vectorization - most compilers feature auto-Vectorization options today- reduces pressure on the execution ports as multiple elements are calculated with same uop.

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.
