1.1The AMD64 Architecture

AMD64 architecture allows end users to run existing, installed 32-bit applications and operating systems at peak performance, while providing a migration path that is 64-bit capable. It is designed to enable 64-bit computing while remaining compatible with the vast x86 software infrastructure. AMD64 architecture represents a new class of computing, enabling a single architecture across 32- and 64-bit environments.
