The design of Bulldozer is heavily revamped from the previous generation. With Bulldozer, the two 128-bit FMA-capable FPUs can be combined into one 256-bit FPU. This design is accompanied with two integer cores each with 4 pipelines, the fetch/decode stage is shared. AMD names this design as a "Bulldozer module". A 16-core processor design would feature eight of these modules. But the operating system will see each module as 2 physical cores.
The fpu's are not the entire chip, its still a 64bit chip, just with larger floating point units.
