AMD64 is for 64bit Amd and Intel processors,
64-bit Intel *x86* processors. There was once another 64-bit architecture called ia64 used by Intel "Itanium" processors, not compatible with amd64.
i386 is a 32bit system for old pre64 architectures. So even though a 32bit will work on a 64bit system I have yet to find a good reason for doing so.
Here are some good reasons to use a 32 bit system on 64 bit hardware : - You are tight on memory (e.g. embedded system). - You need to run software available only for 32 bit architecture.
