The only thing I would add is that Intel, an effort to not appear completely buffoonish, does not refer to amd64. They might use x86_64 more commonly now (I'm not certain), but for a quite some time they used the designation "em64t" (standing for something like "ehananced memory 64-bit something or other"). Occasional references to em64t can be found in some places. It refers to the same thing: amd64 <-> x86_64 <-> em64t. It was a bitter pill to swallow for Intel that they, as the originators of the x86 architecture could have been so far off when it came to the development of the successor 64-bit architecture.
