Oh, no, you're misunderstanding it a little bit. Let's take a moment.
Eons (really just many hardware generations) ago, the x86 architecture was invented. Then, some time after that, some smart lad got the bright idea to strap on 32-bit extensions to it (as it did not have any sort of 32-bit instructions before). Some time after that, AMD was like "how can we make more money?", and then some guy flopped his expendable-incock about on the conference room table and proclaimed "64-bit extensions to x86-32!". And that's how x86-64 was born. But then what is x64, you ask? Marketing jargon that makes no goddamn sense, that's what x64 is.
