Up to this point I assumed the graphics stack for Intel was open source and included in the standard repositories. However, I just became aware that Intel hosts their own special repositories of graphics drivers and software for each of the popular distribution on 01.org. Many of the packages, like xorg-x11-drv-intel and cairo, duplicate what's available in my distribution's repository. Are the Intel-hosted packages any different? What is the benefit of the Intel-hosted ones?

What do the changelogs say? – Ignacio Vazquez-Abrams Jan 27 '14 at 2:36
@IgnacioVazquez-Abrams Can you access changelogs from rpm or yum? – drs Jan 27 '14 at 2:37
Yes. From either. – Ignacio Vazquez-Abrams Jan 27 '14 at 3:03

From the about page on 01.org:

01.org is the online presence of OTC, where we pull together all the open source work that Intel engineers are involved in. Here’s where you can find all the projects we maintain and contribute to in one location, from the most widely known, the Linux kernel, to very focused projects, like oFono and SyncEvolution, to the ones we started here at Intel and provide full hosting for, like PowerTop and the Web Simulator. Each project has its own micro-site, where it’s easy to learn about the project and engage in the community. And Intel open source maintainers and developers will find all the tools needed to host a project.

The packages provided by 01.org would appear to just be the latest that Intel has to offer for packages in which they either develop or participate in the development of said packages.

Example - official Fedora repo

I'm using Fedora 19, if I download the package cairo.

$ yumdownloader cairo
(1/2): cairo-1.12.14-2.fc19.x86_64.rpm               | 689 kB  00:00:01     
(2/2): cairo-1.12.14-2.fc19.i686.rpm                 | 713 kB  00:00:01

Taking a peak at one of these packages meta info:

$ rpm -qpi cairo-1.12.14-2.fc19.x86_64.rpm | head -17

Example - Intel's repo

We can then download the same corresponding .rpm from 01.org, download.01.org, cairo-1.12.16-1.4.x86_64.rpm .

$ wget https://download.01.org/gfx/fedora/19/x86_64/cairo-1.12.16-1.4.x86_64.rpm

Taking a peak at this package's meta info:

$ rpm -qpi cairo-1.12.16-1.4.x86_64.rpm | head -16
warning: cairo-1.12.16-1.4.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID 75e52366: NOKEY

So if you notice, the version of the software from Intel is slightly newer.
