It was exactly the same instruction set.

C compilers didn't offer an "AMD" CPU target* until AMD came out with the "AMD64" instruction set. Today we call this "x86_64" or "x64".

* Feel free to point out some custom multimedia vector extensions for Athlons or something, but the point remains.

And Intel named its licenced implementation of AMD64 as IA-32e, just to make it clear to everyone that it is based on Intel architecture 32bit version with an extension. Luckily they dropped that name few years later
