    Default The Current State Of Radeon Power Management

    Phoronix: The Current State Of Radeon Power Management

    It's been a while since last looking at the state of power management for Radeon GPUs, but here's an updated look at the various options surrounding power management for modern ATI/AMD graphics processors and their effectiveness. Various drivers, graphics cards, and tuning options are compared.

    Default Power usage

    The idea of power management is to reduce the power used and increase battery life. So a benchmark without actually measuring the used power is quite worthless IMHO. What possible conclusion can be draw from this benchmark? That catalyst is still better in power management then the open source drivers? No surprises there.

    Default Haven't we already covered this?

    It wasn't that long ago that several articles were posted that essentially covered all the information in this article, and no announcements have been made to indicate that anything has changed with regards to power management. What's the point in this article? It's essentially just rehashing the same old story.

    And the one interesting thing to compare, how dynpm stacks up against the 'auto' profile, is sorely missing from the test. On my system, dynpm is still far worse, getting 5C higher just idling on the KDE desktop.

    Recently one of the developers said that people doesnt care much about power management, so its not in high priorities. Can we do something about it? May be some poll? There to many work(opengl, glsl, video acc, new chipset) to see usable pm even in year.

    Missing results on the last graph of page 3, Cayman GPU voltage.

    Where's low from the graph? It's mentioned in the text though.

    Michael, the PTS specs on page 2 are terrible to look at. Is this one of those things that's better with a premium subscription? Despite the tablet trend, some of us still have relatively large desktop monitors..

    http://www.phoronix.com/scan.php?pag..._results&num=1 for example? Where power management isn't far behind the other two useful options (2d is mostly fast enough anyway these days, and Gallium and KMS are just means to an end, not that interesting in themselves for end-users).

    Where did they ever say that? I heard them say that it is a lot of effort to get fixed, but never that they do not care. And keep in mind many of the people who are working on those other priorities may not be able to work on power management as they do not know how or in some cases may be told to work on certain things from their employers. As it stands though, the new chip-set enablement definitely seems more important than the others, with the others being more iffy.

    Though that is my opinion, and I do not have any of the skills needed to change the situation, so I am just going to walk off and shut up now.
