Branch misprediction ratio PMC3/(PMC2+PMC3)
Instructions per branch PMC0/(PMC2+PMC3)
LONG
Formulas:
CPI = CPU_CYCLES/INST_RETIRED
Branch rate = BR_PRED/INST_RETIRED
Branch misprediction rate = BR_MIS_PRED/INST_RETIRED
Branch misprediction ratio = BR_MIS_PRED/(BR_PRED+BR_MIS_PRED)
Instructions per branch = INSTR_RETIRED_ANY/(BR_PRED+BR_MIS_PRED)
-
The rates state how often in average a branch or a mispredicted branch occured
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.

Profiling group to measure L2 cache bandwidth. The bandwidth is computed by the
number of cacheline loaded from the L2 to the L1 data cache and the writebacks from
the L1 data cache to the L2 cache. The group also outputs total data volume transfered between
L2 and L1. Note that this bandwidth also includes data transfers due to a write
allocate load on a store miss in L1 and cachelines transfered it the instruction
cache.
