    Looks like AMD might be back to playing the high-end GPU game

    "Quality" is now the default setting for all boards, so if you compare the default quality on Cypress on Cat 10.9 to Cat 10.10 you will actually get opts on, where you didn't before. Because the filtering is improved in NI the default setting is most closely matched to NVIDIA's setting.
    Most of the test show a marked improvement in tessellation, to the point where Brts is pretty much the same performance as GTX 460 in Unigine.
    As mentioned the “default” setting most closely matches NVIDIA’s default setting.

    But why the distinction between EG and NI in driver settings ? why not use the same settings scale ?

    And? This is the 5870, too. But what it with Stone Giant? Or the DX11 Samples from SDK?

    Do you have a proof for it? Because the reviewer, who have a clue, don't think so. PCGH.de finds is worse than nVidia's Quality and Computerbase.de comes to the same conclusion.
    Maybe, and that's my opinion, AMD should not only talk but they should do something for their customers. Cheating and complaining is the wrong way to win.

    Wasn't StoneGiant the one which at High settings throws away 75% of the done tesselation work anyway? (regardless of if you have nV or ATI card)
    I don't see that as valid comparison point for anything

    There isn't any distinction in terms of what software optimizations are applied over the hardware capabilities with these settings; we are using the same setting scale. At the same quality level, though, NI will be better than EG.

    Not yet. OpenMM is the development branch were the OpenCL work is being done and OpenMM is running on Northern Islands. You can read Vijay's updates into umpteen threads on the folding forums about status of the OpenMM support for OpenCL going into a Folding@Home client.

    And its all improved.

    Quality provides similar optimizations at the software level to NVIDIA, High Quality provides native texturing. PCGH also does not take into account the high precision LOD and pure angle invaraint AF that is offered in all modes but not available in NVIDIA hardware.

    It is all good and well to say these things, but at the end of the day, what matters is what my eyes see on the screen. Clearly AMD has remedied the transitions issue; however, if AMD cards are still sparkling/shimmering/flickering/whateveryouwanttocallit where Nvidia cards are not, then it is just an epic failure on AMD's part (it has been 6 years FFS). I'm reserving judgement for now, but the comments in the computerbase.de article do not seem very promising...

    Without a real improvement in perfomance.

    So how would you explain that PCGH thinks your new Quality setting is worse than A.I Standard on Cypress and Quality on Geforce? Do you really think that they are lying?

    There is no "Cat AI standard" going forward. The optimization behaviour has been unified across all boards from Cat 10.10 onwards, so the default beviour on Cypress is different, but you can get back to Cat 10.9 quality on Cyress by changing the slider to high quality.

    You didn't answer my question.
    And why would someone go back when the new setting is as good as the old one?!

    only you sontin could think AMD dropped the ball, if you want to be spercific AMD have relased 3 new "sweet spot" cards in the time NV have release 1 ( the 280's were released like 2 weeks before 4870).

    the chip is 80mm sq smaller then cypress hits almost the same performace at the same power on the same node and its only been a year since cpyress came out, how isn't that hitting the mark? remeber that according to dave that the sweet spot card was juniper not cypress and thats why there is the naming confusion right now because evergreen family wasn't named like it should have been.

    you/NV should thank there lucky stars that 32nm got canned otherwise that 255mm sq die would be tiny, it actually would have been funny (in a sad way) seeing NV having to price the 470 to compete with it.

    I did actually. The default behaviour between Cypress on Cat 10.9 and Barts on 10.10 will be different, and you will get different tradeoff's / IQ between them (i.e the AF band on Cypress and some optimizations on Barts), however the optimization panel had to be unified across all products and now the optimization behaviour is consistent but NI will always offer higher quality.

    Don't feed the troll, he already has a hard time coping with the fact that both GF100 and GF104 have just become obsolete and 6870 Crossfire probably looks like a better option than a single GTX580.

    I don't know about the GF104 being obsolete; I was pretty damn surprised at how well the EVGA 460 FTW card performed in Anand's review. It's $10 cheaper than the 6870 at the moment as well.

    And why do you change the default setting? Why do you decrease your default IQ?
    What was wrong with A.I Standard for the last 3 1/2 years?

    He already answered that too, why don't you actually read his posts?

    Cat AI was becoming cumbersome and confusing in terms of what it did and what got enabled when. This is a much clearer interface, with more control over the settings for the users, without destroying things like Crossfire performance. This is also very similar (perhaps even less confusing) than NVIDIA's options and sets similar optimizations by default. In all, you should be pleased about the new options as its offering more transparency.
