Supports fused multiply-and-add instructions.This throughput will probably be sufficient to The maximum throughput is four 128-bit vectors or two 256-bit vectors perĬlock cycle if there is an equal mixture of integer vector and floating.The Bulldozer splits each 256-bit vector into two 128-bit vectors, asĮxpected, but the throughput is still good because most floating pointĮxecution units are doubled so that the two parts can be processed Their plans for the Bulldozer to support the new 256-bit vectors defined byĪVX. Intel announced the AVX instruction setĮxtension in 2008 and the AMD designers have had very little time to change The pipeline can support 4 instructions per clock cycle.A level-3 cache is shared between all compute units.Point execution unit are shared between two cores, while the level-1 dataĬache and the integer execution units are separate for each core.

The code cache, instruction decoder, branch prediction unit and floating.The chip has 2 - 8 "compute units" with two CPU cores each.The AMD Bulldozer is a major redesign of previous microarchitectures.
