Front End Bandwidth

Front End Bandwidth

TITLE: Front End Bandwidth

ISSUE_NAME: Frontend^FE_bandwidth

DESCRIPTION:

Cycles some uops were delivered by front end when asked to deliver, but maximum bandwidth was not achieved

RELEVANCE:

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.
