    Post will be updated once more reviews are available.

    Note:
    Earlier drivers don't seem to allow for any control of PowerTune from CCC. It appears that driver support for that seem to start with Catalyst 8.79.6.2 RC2

    Edit 2:
    2 Observations so far.
    1. EQAA seems to be AMD's version of CSAA. So IMO would be worth using over MSAA for a performance boost.
    2. Powertuner doesn't seem to help at stock clocks. I'm guessing there maybe something there if the card is over clocked but I've not come across any reviews showing this yet.

    I'm still going over everything right now. Below are a list of features that are available with the card.

    [​IMG]
    This switch allows for a second nonprogrammable bios.





    [​IMG]
    What's interesting is the use of 2xEQAA for gaming should give you AA quality close to 4xMSAA but with a performance benefit. :cool: (taken from one of the reviews)




    [​IMG]
    The use of EQAA is compared to MSAA. (taken from one of the reviews)



    [​IMG]
    Power Tune is a new functioned added with CCC (not the switch on the card). This feature (as written in the slide) seems to be more apt when overclocking (when using the + aspect of Power Tune). Not for stock clocks. But the reviews I've read so far haven't explored using this feature when overclocking the card.

    Edit:

    Check out Sapphire's Website for amd_radeon_hd_6900_series_win7_vista_dec8 drivers.

    very interesting info... i've been reading about voltage adustment... looks like powertune is going to need modding and the real excitement is seeing the improvement above and beyond tdp.... interesting...

    hopefully my card will arrive in the am tommorow, although thats an unlikely prospect...

    as soon as it arrives i'll start benching.... cant wait... first bit of new tech in ages... :D

    Look forward to your findings. I'm interested to know if at +10 (according to w1z's review that's all you need) if overclocking actually improves or not in games. Versus keeping power tune at 0.

    ------
    It's disappointing that AMD has not released a hotfix driver allowing for EQAA and MLAA for 5000 series. I thought perhaps today another drivers would be release. However, apparently they had no such thing planned.

    Odd, all the sites that were doing wow benches stopped. Even tpu did the wow DX11 bench as recently as the 580 review.

    i like the fact that even though there are less shaders than the 5870, the 6970 has more complex stream shaders

    quote from wizards review...
    Compared to the older VLIW5 design in which an SIMD core consisted of four simple and one complex stream processors with some common resources, the new design, dubbed VLIW4, combines four equally-capable complex stream processors, with two of the four getting special functions.

    I didn't include tech report after reading this:
    source

    That comment was so far removed from the review itself that I draw pause and decided to just omit it for the time being. The other's I've not come across yet.

    i think we will be looking at a new release of graphics cards in around 6 months or whenever TMSC gets the act together and works out the 28nm or 32nm.

    Hopefully AMD can get out some really good drivers early that will make use of the changes they have made.

    Only time will tell.

    I don't see how. He makes a very good point that unless sites (or anyone who posts reviews) state what they are setting it to, it just becomes another way to skew bench results does it not?

    Let me put it another way: I can see problems when people start overvolting their cards and even with it set to 20% max, run in to clock gating when playing a game. This will be especially interesting to see when the 6990 comes as the 300w PCIe limit is going to be obliterated with 900Mhz cores. Will 20% be enough? Will there be a higher limit then 20%? Is there any kind of work around?

    Please also add the Bit-tech reviews:

    HD6950
    HD6970

    Benchmarks are lacking (something I have been quite vocal about) but the architecture analysis is there.

    Sorry, but if you believe that is what he was implying then it should have been stated that way. However, that's not the case. So for now I'm not including it.

    Hmm, bit-tech's reviews don't offer any information as to which drivers they are using. As you can see from the OP many are using various drivers

    Well I just took the plunge, I couldn't resist and ordered a 6950 with express shipping so here is to hoping I get it tomorrow and not Monday :cry:

    Maybe he was imply this by that statement (Though I agree that if it was, he should have been more clear. Maybe some more time and another article will allow him to expand on that comment. This is Scott Wasson (not THG if you'll excuse the analogy) and I'd be surprised if it was just an off hand comment. Idk, maybe he just had a bad week..............but anyway.)

    Now this is interesting. Not sure if there's any truth to this but still worth the look :D

    Here is a good way to get an idea of what the slider actually does:

    This is a very sharp difference between his comment and someone getting down into showing data of what the slider actually does.

    I think he may of realised that mussles and may of found it amusing himself and perhaps not of realised everyone else ever has seen it.

    Way to be really patronising dude :laugh:

    hotfix 10.12 was updated. It is called amd_win7_vista_radeon_hd6900_8.79.6.2rc3_dec16.exe making it 2 days old. So click on the link in the news section and download them (d/l it again if you got the previous RC2 version dated Dec 9th). This is for the 6900 series.
