Why Is It Called Amd64?
The first name for the 64-bit extension to the x86 set was called x86-64. It was later named to AMD64 (because AMD were the ones to come up with the 64-bit extension originally). Intel licensed the 64-bit instruction set and named their version EM64T.

64 bit Processor Architecture

Likewise, is Intel a amd64? A: No. "AMD64" is the name chosen by AMD for their 64-bit extension to the Intel x86 instruction set. Before release, it was called "x86-64" or "x86_64", and some distributions still use these names. The architecture is AMD64-compatible and Debian AMD64 will run on AMD and Intel processors with 64-bit support.

Likewise, is amd64 same as x86_64?

There is no difference: they are different names for the same thing. 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.

Do I have amd64 or i386?

i386 refers to the 32-bit edition and amd64 (or x86_64) refers to the 64-bit edition for Intel and AMD processors. Wikipedia's i386 entry: Even if you have an intel CPU, you should use AMD64 to install 64-bit on your computer (it uses the same instruction sets). I highly recommend using it.
