Supperduper AA:
The fourth CrossFire mode calls itself "SuperAA". Here both maps provide not for higher Frameraten, separate for increased image quality. Both maps count the same Frame, but on different FSAA Pattern. The combi he chip sums both pictures up then to one. The user receives thus eightfold edge smoothing with 4x-FSAA speed. With SuperAA also the quality of Shader computations improves. With different Bump Mapping computations arise often unpleasant treppeneffekte. Also these surfaces are smoothed by the combination of the two pictures. Note for enthusiasts: ATI explained that the FSAA Pattern (sample) with Radeon X8xx maps is freely programmable. Thus different FSAA Pattern than the standard Radeon maps does not use the CrossFire edition maps.
Advantage: Duplication of the FSAA factor without geschwindigkeitsverlust (compared with an individual map). Maximum 12x AA and/or 14x AA (12x + 2xS) possible.

So basically your feeling = fact?DSC said:Why do I get a feeling if A.I is disabled, all the profiles stored inside will not work..... so much for claims for not needing profiles.....

It seems that unmatched quad capabilities are turned off, e.g. a 4 quad master working with a 3 quad slave will be reduced to a 3 quad master.
So bang goes all those hours spent speculating over asymmetric quad supertiling schemes.

Why do i get the feeling you pee green? And isnt A.I. recomended by ATI to be enabled anyways? Or is this about driver profiles for certin games. yuck yuck. And "the user is therefore clearly more flexible with ATIs CrossFire than with NVIDIAs SLI." that was the conculsion? i guess you dont take in acount that a XT can cross with a XL?. i gues im feeding a troll. srorry.DSC said:

Google translate URL didn't work
"Map" means "card".

Didn't some people hack Nvidia SLI to work on non-SLI motherboards by putting the second card in a PCIe x1 slot? Seems that it is not fundamentally limited to nForce MBs, but this is merely an NV driver decision to force people to buy nForce. A future driver rev could make NVidia SLI work on other chipsets. From an astract standpoint, I don't really see why the MB chipset needs to provide any support at all beyond the PCIe spec itself.
Two of the reasons the SLI-capable NForce4 chipset has sold well is that
- it was the first PCI-Express capable Athlon64 chipset. Everyone who wanted a PCI-Express MB was forced to buy it.
- Even now when VIA has a decent competitor, the NForce4 remains the most feature rich A64 chipset.
Can anyone confirm that the tier one and two manufacturers will make ATI motherboards? And - it would seem as if the NForce4 is still higher specced, unless ATI has trumps up their sleeve. Anyone care to speculate if this will matter? It shouldn't, if you look at relative costs alone, but on the other hand the attractiveness of the overall package does depend on the motherboards as well.
It will be interesting to see how this plays out.
