    Phoronix: AMD Radeon HD 7950: Southern Islands Isn't Yet A Penguin Holiday

    The Radeon HD 7900 series were announced at the end of 2011 and since then the Linux support status for this hardware has remained a big question. For the Radeon HD 7000 series "Southern Islands" GPU launch, they did not send over any hardware samples so Linux consumers have left to be confused over the state of the non-Windows support for AMD's hardware based on the "Graphics Core Next" architecture. Fortunately, here is finally an extensive look at the Radeon HD 7000 series on Linux with testing of a Radeon HD 7950.

    Thanks for mentioning the ignore list Q is now added

    Unless you have the equipment to directly measure at PCIe slot and extra cable the most convenient method should be to put a power meter directly between wall and computer. That's what I do. Of course you can't actually read the power usage of each component but you can estimate some things and compare. E.g. I did so with CPUs in the same board or GPUs or same GPU with different drivers and operating systems.

    There's a watermark, there isn't.... you just need the official driver, Catalyst 12.2 and you won't have it? It depends on the model of card, no it doesn't.

    Typical AMD. There's tons of confusion and yet, it's the same old story. The support is wanting. I hate to praise Nvidia but there's really no other choice but to compare the two. The support for the proprietary driver is relatively punctual. If the support isn't immediate, you can go to the other related web site and post or read posts and sometimes a Nvidia person replies and asks for someone to test. That's how it should be done.

    AMD has a website for inquiries but guess what, gents, it's for.....WINDOWS!

    One or two AMD ppl post here but it's mostly for OSS driver issues. Once again, repeat after me.... AMD DOESN'T SUPPORT LINUX!

    Oh yeah, I agree with Q. The watermark is pointless. I think people will figure out something's not working and if the hardware is fairly new, that it's not supported yet. What is with AMD and Linux?

    no I'm not bridgmans a spam accound
    really no i'm not a insider ! i'm a jon doe user phoroix member.

    Another way can be, not to alter the original text, but only to update him by adding some sentences at the very end under the title "update", "correction", "addition" or so. This way you get consistency and actuality at the same time. There also may be an "update" notification in the main-title.
    yes i also vote for a disclaimer!

    yes "update" many websites do this in this way for example heise.de

    but you get more clicks and readers if you push out new articles instead! (this is a fact)

    the information can be wrong 1 minute after releasing the article!...
    michael should really make clear that he do not edit his articles to fix the "Future" in the "Past"

    If that is your guideline, I respect that, even if it sounds a bit "old fashioned" for me. But that?s ok for me, I?m old fashioned with other things. It is just important to know such things, so that I can read phoronix articles in the right way. So thanks for the info - good to know.
    Thanks, I am. Already got my own blog since quite a time
    its not my guidline its the micheael/phoronix guideline.

    for myself ""old fashioned"" i like it and i don't like it i like it for other members stuff but i don't like it for my own stuff because i need to edit my stuff a lot because of fixing my shitty writing errors.
    but on the other way its really confusion if you read a text and next time the text do have a different content. for me its better of a book stay fixed in the same words and the new content goes into a new book. (but i don't like it for my own words because i prever to rework them all the time)

    yes this is really a problem because most of the phoronix readers don't know this-

    michael really should write a disclaimer about that and post it in every article to make sure that the information in the article is only right in the "past"fixed by the date of the aricle.

    so yes i'm happy that i can help you in this tropic.

    Thanks if you answer!
    Wow, many questions.
    - 2D-performance: I use KDE and noticed no change in 2D performance, both cards are pretty fast with full effects/compositing under KDE. Only thing is that catalyst restricts my monitor to 60hz instead of possible 75hz. I don?t know if this was the case with nvidia also because I changed monitor (good old CRT 21" to LCD 27") and graphics-card at the same time, and at CRT the whole frequency thing is a completely other story
    - Wine: I made no benchmarks, but wine works as before - I did not test 3D things in wine yet.
    - Video acceleration works through vaapi via vlc 2.0 since some months - in xbmc directly through xvba - so there is also no big difference for me compared to nvidias vdpau
    - OpenCL: don?t use it
    - Win7: for gaming yes. superfast! a big update compared to the gtx260 and even highly overclocked more quiet with my gigabyte windforce 3 model
    - EnergyDrain: don?t know how to measure that, but as win-gaming-performance, this is covered by all the benchmarks out there. To sum them up: idle-power-drain is much lower than with gtx260 (or any other current card not amd7000series). I assume this is also valid for linux? How can I test?
    - bugs: none so far
    - change: was worth it in respect of lower idle-powerdrain, lower noise, lower temperature at load and idle state and higher gaming-performance
    - money: it may a bit too expensive right now, because there is no competition from nvidia right now (delayed kepler). The old GTX580 can?t compete in terms of power drain, noise-level. Only if you look only at perfomance-for-money the 7950 is too expensive. So if you want to save 50-80 bucks wait until Nvidia Kepler arrives... and maybe Kepler is even better, but then it is again quite sure, that the price will also be higher, I think
    - difficulties: none
