TITLE: Front End Bandwidth
Cycles some uops were delivered by front end when asked to deliver, but maximum bandwidth was not achieved
When the front end cannot deliver enough uops when the back end is requesting uops, this can potentially indicate a front end limitation which is affecting performance. The recommendation is to look into the other Frontend metrics to root cause why this occurred.
