Intel 64 compilers generate 64-bit code for x86-64 operating system. They will not work on 32-bit operating system.
Your oldest Xeon may be a pure 32-bit system, which will not support the 64-bit OS. For at least 3 years, all Xeon systems have been capable of running either 32- or 64-bit OS.
If you are running the x86-64 64-bit OS, you can install both compilers, if you choose. The 32-bit compiler would be used to build an application which can run on either 32- or 64-bit OS. Otherwise, you would likely want only the 64-bit compiler.

The first package, IA-32/Intel 64, which includes both 32- and 64-bit compilers, is just a combination of the separate compilers. You can use it to install either or both compilers on 64-bit OS, but only the 32-bit compiler on 32-bit OS.
When you have both compilers installed, you control which one is active by choice of environment setting script.
