Industrial embedded systems, point-of-sale terminals, and CNC machines still run on 32-bit Atom, Geode, or Pentium M processors. A purpose-built 32-bit OS can shave off tens of megabytes of RAM usage compared to a 64-bit OS running the same services. For example, a stripped 32-bit Linux kernel with no 64-bit compatibility layer can boot in under 8 MB of RAM, leaving more for actual application data.
