LONG
Formulas:
Branch rate = BR_INST_RETIRED_ANY/INSTR_RETIRED_ANY
Branch misprediction rate = BR_INST_RETIRED_MISPRED/INSTR_RETIRED_ANY
Branch misprediction ratio = BR_INST_RETIRED_MISPRED/BR_INST_RETIRED_ANY
Instructions per branch = INSTR_RETIRED_ANY/BR_INST_RETIRED_ANY
-
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.
Instructions per branch is 1/branch rate.
