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.
