That is a great question.
There is a great explanation for these architectures (processor types) on wikipedia:
Yeah I tried their first, but X64 and IA64 now lead to the same page. I was looking for a simpler explanation without having to read a gigantic article.

i hope it helps.
I'ts an old question but you must look for the answer on others pages.
For the ones that want a quick response:
x86 versions are for intel compatible 32bits processors
x64 versions are for intel compatible 64bits processors
IA64 versions are for intel itanium processorsbest regards
