I'd have to agree with your assessment of the PPro, but...

Why do you say that only the 21164 is a "True 64 bit architecture"?

There are other, earlier, members of the alpha family that have all of
the 64-bitness traits that the 21164 does...  In fact, there are
no members of the Alpha family that _don't_.  You might mean that the
Alpha is, but "Alpha" != just 21164.
