The difference between AMD64 and IA64

In fact, a lot of people literally, think AMD64 is for AMD CPU, IA64 is for Intel CPU, in fact, is wrong, I originally think so, it is not:

The Intel 64-bit CPU you buy on the market belongs to the AMD64 category. This architecture should be called x86_64, so whether it's AMD's 64-bit CPU or Intel's 64-bit CPU, it belongs to the AMD64 category.

And IA64 refers to the Intel Itanium series CPU, not the X86 architecture. IA64 is mostly used on servers, not on desktops we normally use, which are usually expensive, related memory and hard drives are also expensive!

So you later your PC CPU is 64-bit [with Intel, also has AMD], non-Itanium CPU, you can download AMD64 os for installation.

There are 3 main types of 64-bit computing available on the market for Intel-compatible processors:

1) Intel IA64, based on the Itanium 2 processor, is not compatible with 32-bit applications, the software version of this mode is called XXX for Linux Itanium.
2) Intel EM64T, based on Xeon DP "Nocona" and MP processor, compatible with 32-bit applications, E software version of this mode is called XXX for Linux x86-64.
3) AMD AMD64, based on Opteron processor, compatible with 32-bit applications, the software version of this mode is called XXX for Linux x86-64.

In addition to the common IA32 architecture of the 32-bit processor, the software is relative to the version of this mode called XXX for Linux x86.
