Table B-1 Pentium 4 Processor Performance Metrics (continued)
Metric Description
Speculative Number of uops
Uops Retired retired (include both
instructions executed
to completion and
speculatively
executed in the path
of branch
mispredictions).
Branching Metrics
Branches All branch
Retired instructions executed
to completion
Tagged The events counts
Mispredicted the number of retired
Branches branch instructions
Retired that were
mispredicted. This
stat can be used with
precise event-based
sampling.
Mispredicted Mispredicted branch
Branches instructions executed
Retired to completion. This
stat is often used in a
per-instruction ratio.
Misprediction Misprediction rate
Ratio per branch
All returns The number of return
branches
All indirect All returns and
branches indirect calls and
indirect jumps
All calls All direct and indirect
calls
