Summary
Understanding the behavior of a processor when it features high-priority cores and low-priority cores using Intel® Xeon® Scalable Processors
Description
Some processors feature high-priority cores and low-priority cores.
Resolution
High-priority cores and low-priority cores are related to the Intel® Speed Select Technology. Depending on individual choices and needs, it is possible to set some cores as:
- Intel® Speed Select Technology - Turbo Frequency: high-priority cores to give them a turbo frequency that exceeds the nominal turbo frequency limits when all cores are active.
- Intel® Speed Select Technology - Performance Profile: to make them receive the surplus frequency first.
- Intel® Speed Select Technology – Base Frequency: applying to them a higher base frequency.
Please check the specification of your Intel® Xeon® Scalable Processor.
