На сегодняшний день существуют 2 вида разрядности операционных систем, это 32-х разрядные и 64-х разрядные. Х86 - это старая архитектура оборудования. Для такого оборудования используется 32-х разрядная ОС. Х64 - это современная архитектура оборудования. ОС для такого рода архитектуры обычно носят префикс х64.

Hans and DarkDust answer covered i386/i686 and amd64/x86_64, so there's no sense in revisiting them. This answer will focus on X32, and provide some info learned after a X32 port.x32 is an ABI for amd64/x86_64 CPUs using 32-bit integers, longs and pointers. The idea is to combine the smaller memory and cache footprint from 32-bit data types with the larger register set of x86_64. (Reference: Debian X32 Port page).x32 can provide up to about 30% reduction in memory usage and up to about 40% increase in speed. The use cases for the architecture are: option. When building a kernel, you must include the option. (Reference: Debian X32 Port page and X32 System V Application Binary Interface).Here is some of what I have learned through a recent port after the Debian folks reported a few bugs on us after testing: to install the X32 chroot environment, and (3) to enter into the environment and test your software.
- vserver hosting (memory bound)
- netbooks/tablets (low memory, performance)
- scientific tasks (performance)
syscall.x32=yCONFIG_X86_X32=y- the system is a lot like X86
- the preprocessor defines (and friends) and
__x86_64__, but not__ILP32__/__i386__(and friends)__i686__ - you cannot use alone because it shows up unexpectedly under Clang and Sun Studio
__ILP32__ - when interacting with the stack, you must use the 64-bit instructions and
pushqpopq - once a register is populated/configured from 32-bit data types, you can perform the 64-bit operations on them, like
adcq - be careful of the 0-extension that occurs on the upper 32-bits.
