What is AMD64?
AMD64 is AMD’s 64-bit platform that extends the industry-standard x86 instruction set architecture and defines a new class of computing. The AMD64 platform is the first designed to deliver compatibility with existing x86 solutions and world-class 64-bit performance. Since the introduction of the AMD64 architecture in 2003, the AMD Opteron™ processor for servers and workstations and the AMD Athlon 64 processors for desktop and notebook computers have earned more than 80 awards for innovation and performance and the support of more than 2,000 OEMs, hardware and software developers, system builders and distributors.
