    www.aticrossfire.com outlines the ability to use an existing ATI video card as a dedicated physics card (using HavocFX) and then have additional ATI cards (crossfire or not) for graphics.

    What current model ATI cards will be capable of being this dedicated Physics card?

    On that website they say an X1600XT will still be twice as fast as the Ageia PhysX (for physics), and an 1900XT 9 times as fast.

    What about an X800XT? Is that capable of being the dedicated physics card?

    Cheers

    I would say that you could use any of the AVIVO PCI-E cards

    How the hell can it be so much faster then AGEIA....this whole situation is bullshit.

    The ATI solution won't work on something that is written for AGEIA and vice versa. So how the hell can it be 9x faster?

    It's a stupid statment. There is already a physx thread in the Video Card section that goes into this in a lot more detail

    Perhaps their meaning is more towards that Havok (with an x1600) can do the same thing as ageia, but 6x more efficiently.
    No doubt they would have padded that claim by a monumental ammount, however.

    I'm not blind to the fact that ATI will add a degree of twist to the comparison to make their product look more favourable.

    My simple question is will an X800XT or an 'older' generation of ATI PCI video card be suitable for a dedicated HavocFX physics card.

    My '9 times faster' is irellevant and probably didn't need to be added.

    The simple answer then is NO. Only X1K series cards, and they recommend the X1600's or better.

    OK thanks FLB.

    Whats the technical reason why not?

    Probably because pre X1xx series don't have Avivo?

    I don't know what Avivo is, but if thats the answer - then thankyou.

    Avivo is a technology developed by ATI so you can use your video card to encode/manipulate video, instead of the CPU. Only X1xx series cards are equipped with it.

    I'm assuming based on the requirements of an X1xx card that Avivio is a key factor to the "ATI HavocFX" physics rendering system. Although I could be wrong.

    EDIT: I'm completely wrong here. It has nothing to do with Avivo, it's based around the architecture of the card. Look here for the ATI explanation. ATI are claiming that entry level X1xx cards would be better at physics processing than desktop CPU's. It may work better because the cards are optimised for Avivo, but Avivo itself does not directly contribute to physics processing.

    AVIVO stands for Advanced Video In Video Out

    I maybe completely off the mark but I dont see what AVIVO has to do with it, from my understanding the Havoc FX requires SM3 which is why the X1xxx range is the only range from ATI that can do it. I also heard that the roll out has been delayed upto 12 months, I dont know if this is when games supporting it will start to be released or for technical reasons.

    As Azz-AmoebA said it is all down to SM3.0, reason being is because SM3.0 introduces Dynamic Branching allowing for more traditional calculations to be performed on the GPU for GP-GPU based applications.

    Avivo is purely ATI's suped up Vivo solution.

    I certainly expect that this is the case. Even if the claim about the X1600XT was correct, the X1900XT shouldn't be 4.5x as quick as an X1600XT in anything.

    Now now settle down, just because you havent heard about it doesnt mean its *bullshit*.
    http://www.ati.com/technology/crossfire/physics/index.html

    Looks quite interesting, specially if like me you have a spare X1 series card sitting around. In the white papers it compares Ageia PhysX and X1900XTX using sphere to sphere collisions/second... Ageia = 530 Million... XTX = 5 Billion
    All we need now is support in the shape of drivers :Paranoid:

    There was an article which claimed a statement from ATI saying that physics ability for their card wont reach comercial use for around a year. Unfortunately i cant find it now - that was about 1 month ago.

    If only i could find some ATI based M/Bs for AM2
