Description
The number of
clockticks.while a
processor is not in
any sleep modes.
The number of
clockticks that the
processor is in not
halted nor in sleep.
Non-bogus IA-32
instructions executed
to completion. May
count more than
once for some
instructions with
complex uop flow
and were interrupted
before retirement.
The count may vary
depending on the
microarchitectural
states when counting
begins.
Cycles per
instruction for a
physical processor
package.
Cycles per
instruction for a
logical processor.
Non-bogus μops
executed to
completion
μop per cycle for a
logical processor
