After we reported that the anisotropic filter of the HD 5000 series seems to work perfectly angle-undependent - though the slight angle-dependency of the HD 2000- to HD 4000 series would not differ a lot from the better and round blossom of the HD 5000 series -, it leaks through from other sources that the main problem has not been pursued.
So we have information on hand that the filter is still flickering stronger than on current Geforce graphic cards, which relates to under-sampling. By this, although ATI saves two frequencies of the texture units and so gains higher performance, the screen quality has to suffer.
If at least the quality without A.I. will be available with other options, we can not be certain, yet.
Anyway, we can already be disappointed, that AMD did not learn from the past and refuses perfect image quality for the purchasers of a high-end graphic card, although performance is available en masse, as so often.
Almost cynically said, that Crossfire does not work anymore with A.I. deactivated - and so with still acceptable filter performance. So purchasers of multi GPU systems or X2 cards will still be locked out completely.
