64-Bit Fedora

64-Bit Fedora

Advances in computing saw the introduction of 64-bit, x86-compatible CPUs from AMD in the spring of 2003. The only platform at launch to support the new technology was Linux. Intel's EM64T extensions for x86, which largely mirror the advances made by AMD, have further increased the availability of commodity x86-64 hardware.

As a direct response to the growing 64-bit user base, Fedora released a 64-bit version, allowing the use of Fedora on AMD64 and Intel hardware. If you have a 64-bit CPU, you are strongly encouraged to get involved and give it a try — just bear in mind that, because the architecture is still quite new, there might not be a 64-bit version of all the software you require.

However, because the Intel Itanium platform uses a radically different set of instructions that are not compatible with the x86 instruction set, the 64-bit version of Fedora does not support Itanium or Itanium2. There are members of the community who are working toward making the Itanium a supported platform, but the niche nature of the platform means that this is unlikely.
