AMD FX 'Bulldozer' processor

Bulldozer-based implementations built on 32nm SOI with HKMG arrived in October 2011 for both servers and desktops. The server segment included the dual chip 16-core Opteron processor codenamed Interlagos (for Socket G34) and single chip 4–8 core Valencia (for Socket C32), while the 4–8 core Zambezi targeted desktops on Socket AM3+.[5][6]
Bulldozer is the first major redesign of AMD’s processor architecture since 2003, when the firm launched its Athlon 64/Opteron (K8) processors, and also features two 128-bit FMA-capable FPUs which can be combined into one 256-bit FPU. This design is accompanied by two integer cores each with 4 pipelines (the fetch/decode stage is shared). Bulldozer will also introduce shared L2 cache in the new architecture. AMD calls this design a "Bulldozer module". A 16-core processor design would feature eight of these modules,[7] but the operating system will recognize each module as two physical cores.
The module, described as two cores, can be contrasted with a single Intel core with HyperThreading. The difference between the two approaches is that Bulldozer provides dedicated schedulers and integer units for each thread, whereas in Intel's core all threads must compete for available execution resources.
