The Bulldozer has a completely new microarchitecture which differs in some interesting ways from the old one. The most important one is that cores come in pairs called "compute units", they share a FPU, L2 and L1 instruction caches and a frequency domain.
It is indeed an interesting design. Desktop Bulldozer CPUs seem best avoided but Opteron 6200 seems quite useful and turns in very good SPEC benchmark results. Opteron 6200 is competitive with much more expensive Xeon CPUs for threaded server and HPC type loads.
With assistance from a local hardware vendor, I hope to observe OpenIndiana running (or not) on a two-socket Opteron 6200 system, at least for an hour or two.
