basically BD witll be equal to SB in AVX if all things are equal, due to having 4 pipelines of 256bit
but since not everything is on avx yet, what happens when theres only 128bit commands? then BD has 8 pipelines, and SB has only 4.

so in your opinion the ONLY thing thats missing from calling all 8 BD cores, actual cores, is that its missing 4 avx pipes?
