No, they don't both use the exact same name, and there appears to be no
consistent naming scheme. Currently, we have:

x86-64: Old official name from AMD, used by as a target name in
        binutils, gcc, autoconf, etc. Cannot be used as part of an 
        identifier in C and some other programming languages.
i386:x86-64: Used in some places in binutils. Not useful for much else.
x86_64: Used in the kernel and in RPM. Cannot be used as an arch 
        identifier for dpkg.
x8664:  Used only in a few strange places, e.g. http://arecorlib.sf.net/.
        Can always be an identifier but looks like a number.
AMD64:  Official marketing term, works fine but is not used in any source
        code so far. If Intel ever starts shipping x86-64 CPUs, they won't
        like this.
amd64:  The same as AMD64 without the shouting.
