atom_64 (Sub-architecture)

Note

This page describes a sub-architecture for Funtoo Linux, which is a particular set of optimizations that is used for a Funtoo Linux build.

The Intel Atom Processor is the common name for Intel's Bonnell microarchitecture, which represents a partial revival of the principles used in earlier Intel designs such as P5 and the i486, with the sole purpose of enhancing the performance per watt ratio. Successor to the Intel A100 series (Stealey), which was derived from the Pentium M, the Intel Atom has been produced since 2008. Targeted at low-power devices, Atom processors can be found in a wide range of notebooks, tablets and small form-factor desktops and servers.

The atom_64 sub-architecture supports 64-bit capable Intel Atom CPUs. The first 64-bit capable Intel Atom CPUs were the Intel Atom 230 and 330, released in late 2008. However, Intel also continued to produce new 32-bit Atom Processors after this date. For example, the Atom N2xx series Atom Diamondville models cannot support 64-bit operation, while the 2xx and 3xx Diamondville, Pineview, Cedarview and Centerton can. A full list of 64-bit capable Intel Atom Processors can be seen here.

Important

For 64-bit support to be functional, a 64-bit capable Atom Processor must be paired with a processor, chipset, and BIOS that all support Intel 64. If not all hardware supports 64-bit, then you must use the atom_32 subarch instead.
