TITLE: Back End 2 Uops Executed
Cycles where the core executed a total of 2 uops
This metric represents how often the core executed a total of 2 uops in a cycle. Depending on the instruction mix, when 2 uops are executed, this could indicate a bottleneck since the maximum bandwidth of uops in execution was not achieved.
If this metric is high, and you expect more than 2 uops executed per cycle you will want to look at the other Backend metrics to try and root cause why the core executed 2 uops in a cycle.
