So unless you are in fact using an Itanium-based Workstation the *_amd64.deb file should run on your system.

32-bit programs are named i386 in honor of the Intel i386, the first commercial 32-bit CPU.

64-bit programs are named AMD64 in honor of the AMD Athlon 64, the first commercial 64-bit CPU.

It's just nomenclature. If it's a 32-bit file, it'll work on AMD or Intel, and the same is true of 64-bit programs.
