So, the Bulldozer/Piledriver/Steamroller/Excavator CPUs all have modules. (An octo-core CPU has four modules, eight cores.) Is it correct, that in one module the two cores can run at the same time when only running 128-bit code? Is it true that when the two 128-bit pipelines combine to perform AVX/256-bit operations, only one core can be active?
