AMD's next-generation "Zen" x86-64 CPU micro-architecture will support up to 32 cores per socket, according to leaked Linux kernel patch on LKML. We know from older reports, that AMD clumps groups of four cores in subunits it calls "Zen quad-core units." Not to be confused with its current "module" design, a quad-core unit is a group of four completely independent cores, which share nothing other than an L3 cache. TechFrag used this bit to deduce that the "Zen" architecture is scalable up to eight quad-core units per socket, or 32 cores per socket.
