AMD64 is AMD’s 64-bit computing platform that extends x86 and defines a new class of computing. AMD's enhancements to the venerable x86 architecture allow users of personal computer clients, workstations and servers to migrate seamlessly to the superior performance of 64-bit computing.

This new class of computing was designed to be directly in the evolutionary path of x86, allowing the technology industry to build a unified 64-bit computing infrastructure fully compatible with the ubiquitous x86 architecture. The AMD64 computing platform allows the latest in processor innovation to work smoothly with the existing installed base of 32-bit applications and operating systems, and builds momentum towards an increasing installed base of native 64-bit environments.

AMD64 Technology enables the industry to advance software development on all fronts, with x86 compatibility, while providing the capability of delivering 64-bit technology benefits.
