Intel HD and Iris Graphics are integrated GPUs commonly found on Intel CPUs. Their performance and their driver support in, has been improving at a steady pace for several years now. Since 2008 Intel's drivers are open-source, and are generally agreed upon to be excellent in quality and well maintained by Intel. Intel Integrated GPUs seem to be an excellent choice for a MythTV frontend.

If you have any experience with these GPUs in MythTV frontends, please add it to the experience matrix so others can benefit from your experience!

Performance and power consumption

Since the release of the GMA X4500, the 3D performance of Intel GPUs is now within reach of nVidia's integrated offerings, see here. This would seem to indicate that an X4500 is more than enough for typical MythFrontend duties. These GPUs can use the VAAPI libraries for hardware accelerated decoding.

Users and reviewers often claim that Intel GPUs have very low power consumption. There seems to be consensus that integrated GPUs in general (including the Intel GMA) are much more power efficient than discrete ones.


Known Issues with MythTV
