32-bit and 64-bit hardware support All Atom processors implement the x86 (IA-32) instruction set; however, support for the AMD 64 instruction set was not added until the desktop Diamondville and desktop and mobile Pineview cores. The Atom N2xx and Z5xx series Atom models cannot run x86-64 code.[25] The Centerton server processors will support the Intel 64 instruction set.[7]
