  1. x86-64

    x86-64 is the 64-bit version of the x86 instruction set. It supports vastly larger amounts of virtual memory and physical memory than is possible on its predecessors, allowing programs to store larger amounts of data in memory. x86-64 also provides 64-bit general purpose registers and numerous other enhancements. The original specification was created by AMD, and has been implemented by AMD, Intel, VIA, and others. It is fully backwards compatible with 16-bit and 32-bit x86 code. Because the full x86 16-bit and 32-bit instruction sets remain implemented in hardware without any intervening emulation, existing x86 executables run with no compatibility or performance penalties, whereas existing applications that are recoded to take advantage of new features of the processor design may achieve performance improvements. Prior to launch, "x86-64" and "x86_64" were used to refer to the instruction set. Upon release, AMD named it AMD64. Intel initially used the names IA-32e and EM64T before finally settling on Intel 64 for their implementation. Some in the industry, including Apple, use x86-64 and x86_64, while others, notably Sun Microsystems and Microsoft, use x64 while the BSD family of OSs and several Linux distributions use AMD64.
