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 full compatibility with existing x86 solutions and world-class 64-bit performance. The AMD Athlon 64 processor allows pervasive adoption of the AMD64 platform for desktop and mobile personal computers. AMD64 replaces terms such as "Hammer" (now AMD64 Platform) and x86-64 (now AMD64 ISA). AMD's 64-bit strategy allows the latest in processor innovation to work smoothly with the existing installed base of 32-bit applications and operating systems, while establishing an installed base of systems that are 64-bit capable. AMD64 can deliver industry-leading performance on all your software applications. The AMD Athlon 64 processors run today's x86 software natively with no "emulation mode" to degrade performance. Software optimized for AMD64 can capitalize on vast addressable memory and the 64-bit architectural enhancements required by the most demanding consumer and enterprise applications, including scientific computing, CAD/CAM/CAE, digital content creation, and ERP/CRM solutions.
