The new 64-bit Microsoft Windows® operating systems include full 64-bit support for AMD Athlon™ 64 and AMD Opteron™ processors. Operating systems take advantage of new architectural features of these AMD64 processors to offer improved performance, scalability and security. While the 64-bit OS offers excellent backward compatibility and performance with 32-bit applications, developers can often achieve substantial performance benefits by porting code to native 64-bit mode.

In this area, find compilers, debuggers, technical documentation, downloads, libraries, profilers and performance analyzers for the optimization, porting and testing of AMD64-based processors on Windows.
