The manual doesn't mention the role the AGUs play in mem + op at all, not even as a footnote. It also indicates that loads use the EX ports when they're supposed to be AG port only.
The obvious difference between K10 and BD is one less execution port. Does that not constitute as a significant difference to you? Of course it's not like K10 was the performance leader (nor was K8 in the end) so remaining the same wouldn't exactly be anything to brag about. But BD manages to take a step back in some regards. Still it'd seem to you that the execution arrangement per core is fine and the cache hierarchy is fine so I guess BD must be fine, and everyone who disagrees is just testing it wrong.
