If I recall correctly (sorry, don't have time to verify via Wikipedia, etc.)...
Intel's original 64-bit architecture/instruction set (for Itanium processors) was not a commercial success... at least not in the consumer space. The instruction set used by Intel's non-Itanium processors is more-or-less the same as the one that AMD adopted for their original 64-bit processors (Itanium competitors?)... I'm not really sure who created that instruction set (AMD, Intel, other?)... but AMD is usually given the "credit" as you have found... although I feel the "x86-64" phrasing to be more clear/accurate (although more easily mistaken for just plain old "x86". I'm sure someone here has a deeper understanding, better recollection, and/or or more time to look it up right now than I do... hopefully I haven't led you too far astray. :-) On Tue, Jan 15, 2013 at 5:21 PM, Richard C.
