Formulas:
Branch rate = BR_INST_RETIRED_ALL_BRANCHES/INSTR_RETIRED_ANY
Branch misprediction rate = BR_MISP_RETIRED_ALL_BRANCHES/INSTR_RETIRED_ANY
Branch misprediction ratio = BR_MISP_RETIRED_ALL_BRANCHES/BR_INST_RETIRED_ALL_BRANCHES
Instructions per branch = INSTR_RETIRED_ANY/BR_INST_RETIRED_ALL_BRANCHES
-
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.

Group to measure cache transfers between L1 and Memory. Please notice that the
L3 to/from system metrics contain any traffic to the system (memory,
Intel QPI, etc.) but don't seem to handle anything because commonly memory read
bandwidth and L3 to L2 bandwidth is higher as the memory to L3 bandwidth.

False-sharing of cache lines can dramatically reduce the performance of an
application. This performance group measures the L3 traffic induced by false-sharing.
The false-sharing rate uses all memory loads as reference.
Intel SandyBridge EP CPUs do not provide the events to measure the false-sharing
over CPU socket boundaries.

Profiling group to measure L2 cache bandwidth. The bandwidth is computed by the
number of cache line allocated in the L1 and the number of modified cache lines
evicted from the L1. The group also output total data volume transferred 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 traffic caused by misses in the
L1 instruction cache.

This group measures the locality of your data accesses with regard to the
L2 cache. L2 request rate tells you how data intensive your code is
or how many data accesses you have on average per instruction.
The L2 miss rate gives a measure how often it was necessary to get
cache lines from memory. And finally L2 miss ratio tells you how many of your
memory references required a cache line to be loaded from a higher level.
While the data cache miss rate might be given by your algorithm you should
try to get data cache miss ratio as low as possible by increasing your cache reuse.

This group returns information about the instruction pipeline. It measures the
issued, executed and retired uOPs and returns the number of uOPs which were issued
but not executed as well as the number of uOPs which were executed but never retired.
The executed but not retired uOPs commonly come from speculatively executed branches.
