Well the other thing, and the most likely thing is that R11.5 isn't limited by fpu power at all for BD. Given the scaling on the BD leaks, adding another thread on the same module doesn't drop performance of either thread. If you look at intel HT, it doesn't reach the scaling AMD gets while the fpu is also SMT like. (running 2threads on them is hurting performance of each thread dramatically)

So performance of R11.5 isn't limited by the fpu resources but by something else on BD. Would also expleain why the leaked sisoft and other benchmarks the BD is ahead of the K8like architecture in fpu on a core and clock basis.


edit: i'm with drfedja on this.
