AMD bulldozer module represents a new direction in microarchitecture and includes a number of firsts for AMD, including AMD multithreaded X86 processor, implementation of a shared level 2 cache, and X86 processor to incorporate floating-point multiply-accumulate (FMAC). This article discusses the module multithreading architecture, power-efficient micro architecture, and subblocks, including the various microarchitectural latencies, bandwidths, and structure sizes.
