That's just plain wrong, ia32 and ia64 are different architectures,
which covers more than just the instruction set; furthermore the
instruction set of an i386 is indeed different to that of a i486,i586 or
i686 since each generation of processors added new instructions. It's
fair to say that the AMD k7 is an ia32 architecture chip that implements
a superset of the i386 instruction set.

The Itanium (and Itanium II) are not newer versions of the Alpha, they
are quite different processors. 

Lastly, it's worth noting that recent Semprons are neither ia32 or ia64,
but x86-64 :-)
