UOPS_ISSUED.ANY & UOPS_RETIRED.ANY

[Tushar_S_]

Hi All,

UOPS_ISSUED.ANY rate/sec is more that UOPS_RETIRED.ANY rate/sec. Is that always correct?

In one test that I am observing that retired UOPs is more than issued UOPs.  Just want to understand in what situation that could happen.

Thanks

UOPS retired all, means "actual retried uops", counts all actually retired uops. 

UOPS issued any, means "Uops that Resource Allocation Table (RAT) issues to Reservation Station (RS)" - uops are issued but not retired.
