AMD Zambezi core
AMD Zambezi core and the first FX-Series microprocessors were launched in October 2011. Zambezi is based on Bulldozer microarchitecture, and it is manufactured on 32nm process. Internally, the core is organized as 2, 3, or 4 Bulldozer modules, coupled with shared 8 MB level 3 cache and on-chip DDR3 memory controller. Each Bulldozer module integrates two CPU cores, that share some circuitry, such as instruction fetch and decode logic, L1 instruction cache, L2 cache, and Floating-Point Unit. The core incorporates all technologies, found in AMD K10 microarchitecture, and adds SSE4.1, SSE4.2, AES and AVX extensions to instruction set. Currently (January 2012), Zambezi core is utilized only in desktop processors.
