Based on the IA-32-x86 architecture (which was introduced with the intel 80386 CPU), AMD and intel both developed an extension to allow 64 bit addressing. intel first started with a new architecture known as IA-64 (Itanium) which is not compatible with previous software. AMD instead developed a compatible extension x86-64, and intel realized how useful it is to continue using existing 32-bit software while developing 64-bit software with mostly the same instruction set for the future, and developed AMD's x86-64 architecture further with own extensions...
So if you don't have specifically an Itanium Server software for Windows running on an Itanium CPU, which I doubt a lot, then you will have a 64-bit Windows running on a CPU compatible to the AMD64 or x86-64 instruction set architecture. But there are also other operating systems running on such processors, it doesn't have to be Windows.
Talking about a 64-bit Windows, you can see Win64 and AMD64 and x86-64 (sometimes even x64) as more or less equal. As long as it does
not explicitly say IA-64 / Itanium.
