Actually, it was AMD themselves who started switching the name from AMD64 to x86_64... Now x86_64 is the "generic" name for AMD64 and EM64T (Extended Memory 64-bit Technology) as Intel named its implementation.

Yup - x86_64 is the name for the architecture, like i386, i686 or x86. AMD [Processor Name] 64 is usually what AMD uses to denote their processors that are 64-bit capable (ie AMD Athlon 64 X2)

Actually AMD were the first to come up with a 64-bit capable x86 chip, hence at the beginning it was called AMD64, as Intel followed suit and also made their x86 chips 64-bits capable, the architecture changed name to x86_64 (even though each company have their own name for their implementation of the architecture).
