Is my i7 920 Intel processor considered ia64 or x64?
ia64 is a reference to the relative flop that is Itanium.
The i7's use x64, aka: amd64 or x86-64, or Intel 64 (EM64T). They all refer to essentially compatible 64-bit extensions. For more info on those, check here

Too bad about the ia64 architecture. Really slick. If it (and the required compilers) got the kind of development that we keep dumping into x64, I believe we'd all be better off. :-( – Brian Knoblauch Aug 12 '09 at 19:46
x64. ia64 is the Itanium architecture which is found mostly on enterprise class servers.
In layman terms, current itanium is IA64. It can only run 64 bit. I7 is x86-64, can run both.
