Only for marketing-spin meanings of "64 bit CPU".  It implements the
Intel x86 instruction set, which is a 32-bit instruction set.

In fairness to AMD, I can't find any claims that the Athlon is a 64-bit
CPU on their web site.

Yes.

It wouldn't work at all, as the Alpha instruction set has nothing to
do with the Athlon.
