All review systems that you've seen have utilized a BIOS patch to workaround the errata which does in fact impact performance.

B2 is the mask revision for higher speed parts. AMD will announce these in Q4 and ship for rev. either at the end of Dec. or Jan. these will be 2.5 and 2.6 parts.

It seems strange that AMD have been shipping BA chips to customers for a while and then supply bugged B1 chips to the reviewers fixed by a BIOS patch. Something does not add up there.
