In some tasks I would expect this to be the case.
Very few architectural shifts result in improved IPC in everything. There are usually a few situations where things don't noticeably improve, or even get slightly worse.
Cinebench makes pretty heavy use of double precision FP, but doesn't take advantage of AVX or the like. It's not implausible that six Phenom II FPUs can match, or beat, four BD FPUs in some situations, especially those that have no awareness/optimization for the changes to BDs architecture.
