The AMD Athlon 64 processor is the first and only Windows-compatible 64-bit PC processor. The AMD Athlon 64 processor runs on AMD64, a revolutionary technology that allows the processor to run 32-bit applications at full speed while enabling a new generation of powerful 64-bit software applications. Advanced 64-bit operating systems for the AMD64 platform from Microsoft, Red Hat, SuSE, and TurboLinux have already been announced, and they only run on processors with AMD64 technology.
Features: Native execution of 32-bit software, allowing today's PC software to provide leading-edge performance while enabling a seamless migration to 64-bit software.
The AMD64 core provides leading-edge 32-bit performance and support for future 64-bit applications: AMD64 technology provides full speed support for x86 code base for uncompromising 32-bit performance, with readiness for 64-bit applications.
40-bit physical addresses, 48-bit virtual addresses.
