    Since 10h could do 1x128bit load and 1x64bit store,basically 2x load capability of K8,without even using the 3rd AGU(look at AT article,3rd AGU was redundant/unused but kept for other reasons-symmetry of the units),i don't see how AMD couldn't double this with BD. BD will have a full OoO load/store capability,different what K8->10h brought(limited to loads only). There are other clues about 2 load/1 store per core,namely GCC source code that describes BD scheduling.
