AMD64 is AMD's official name for the instruction set.

Intel call it EM64T.

It is all one, though, and it better named x86-64.

99% compatible. Intel's original implementation missed out a couple of
AMD's instructions, so the first code targetted at AMD's chips would
not run correctly on the later Intel chips that copied AMD's design.

The code was quickly fixed to run on both. I believe that later Intel
chips fixed the problem and are now even more code-compatible but
there are still a few instructions that behave differently. However,
pretty much all current x86-64 bit code targets the common subset and
will run perfectly on either.

That's "Core Duo". The Core Solo & Core Duo are 32-bit processors with
no 64-bit support whatsoever. They can only run ordinary x86-32 code,
in common with every x86 chip since the 80386 in 1987.

The forthcoming Intel processors currently codenamed "Merom" and
"Conroe" will be the first of the new Core-architecture chips to
support x86-64.
