nope.

BA is the fixed B1 rev that patches AMD errata 281 (stream, int, float performance). No production systems will use B1 chips. PERIOD. straight from AMD's mouth about 30 minutes ago from the field application engineer who has to support this. 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.
