General Retirement

Metric Description

This metric represents a fraction of slots during which CPU was retiring uOps not originated from the Microcode Sequencer. This correlates with the total number of instructions executed by the program. A uOps-per-Instruction ratio of 1 is expected. While this is the most desirable of the top 4 categories, high values may still indicate areas for improvement. If possible focus on techniques that reduce instruction count or result in more efficient instructions generation such as vectorization.

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.
