On current Windows, yes.
But not on OS X nor Linux nor Solaris nor FreeBSD ....
It indicates the type of CPU, or more precisely the instruction set the
CPU is running. x86_64 CPUs (as used by most current Windows boxes) can
emulate i386 CPUs. So the architectures for R on Windows are
x64 (64-bit, the Windows name for x86_64).
