Formulas:
|
|
Branch misprediction ratio = BR_MISSP_EXEC / BR_INST_EXEC

-
|
|
The rates state how often on average a branch or a mispredicted branch occurred
|
|
per instruction retired in total. The branch misprediction ratio sets directly
|
|
into relation what ratio of all branch instruction where mispredicted.
