    See:-

    http://www.asus.com/news_show.aspx?id=1304

    These motherboards use the new nForce4 X16 chipsets, giving x16 PCIe
    channels to BOTH video cards ( or any other card occupying the extra
    "video" slot if not operating in dual-SLI mode --- x16/x16 instead of
    the current x16/x1 in non-SLI mode ). They also employ some form of
    passive cooling called "Stack Cool 2" -- no pictures of the
    motherboards available yet.......... )

    For more details on the X16 chipsets, see:-

    Blah blah, and they possess absolutely zero performance advantage over the
    Asus A8N.
    Asus engineers have been looking at too many Pamela Anderson pictures...

    Isn't it 8x/8x anyway?

    I like to maximally future-proof when building a new very
    high-performance system - for which I am presently beginning to list
    the components. The x16 (instead of x1) extra "video" slot for those
    of us not necessarily contemplating SLI is very interesting indeed -
    think of the AGEIA physics chip on a x16 PCIe board, for
    example............
    Anything to keep them happy churning out new ideas in passive
    cooling.

    Other areas of your system will go obselete long before the PCIe x8
    interface to each SLI card is maxed out. M2 CPU socket. > 4GB RAM. BTX form
    factor...
    The things that must happen for AGEIA to be useful:

    - Working silicon
    - Board implementation (though BFG is on this)
    - Good drivers
    - Extension in DX or certain Open API to support it
    - Game support
    - A tangible improvement in speed/realism once the above requirements are
    met

    The last one may actually be a major stumbling block, since the AGEIA card
    will have to communicate with the vid card. PCIe x16 is still *much* slower
    than local video RAM access.

    Abit's passive heatpipe cooler is actually very effective at carrying heat
    away from the southbridge and voltage regulators. However, you STILL need a
    fan in the case to whisk the heat out.

    Enjoy BTX especially when your video card overheats in spillover
    exhaust air from the CPU (particularly the Intel variety of CPU).
    Remember that BTX was dreamed up by those power-saving wizards ---
    Intel, with nary a thought of properly cooling anything else except
    their inefficient CPUs, RAM and Intel's embedded-video chip-sets.
    No thought of efficiently-cooling third-party peripheral cards - not
    at all in Intel's financial interest. Not many takers yet for
    BTX....... I wonder why ?
    Really ? And what does a physics chip have to communicate DIRECTLY to
    the video card ?
    Yuk, and it sacrifices the parallel and serial ports for zero
    benefit.. The current Asus A8N-SLI Premium passive solution is much
    better than this hack. And poor old Abit is having a teeny weeny
    financial problem at the moment anyway. Seems as if they have
    concentrated too much on gimmicks like "Fatal1ty", OTES, uGuru etc,
    and not listened to their customers. I have been a faithful Abit
    customer for years from BH6 to IC7-G with nary a break. My next
    motherboard purchases will NOT be Abit.
    Sure, of course. Preferably 2.

    High-end BTX Gateway system. Keep in mind 90% of high-end video cards go
    into these OEM boxes.
    http://www.hardocp.com/article.html?art=ODA1

    BTX was indeed dreamed by Intel with little common sense, along with PCIe,
    DDR2, LGA CPU packaging... The ONLY reason the AMD64 platform adopted *one*
    of these technologies is for SLI-support.
    The physics output has to go somewhere, right? All the geometry transform is
    still done by the video card. In fact, the more the game depends on
    programmable shaders, the worse the I/O impact. All the talk about geometry
    instancing and hardware flow control means the video card has to manage its
    communication with the physics card.
    The current A8N SLI passive solution leads to nowhere. It connects the
    voltage regulator heat sink with the chipset heat sink, but relies on "bleed
    air" from the CPU fan to cool everything.
    Abit, DFI, these brands have no OEM sales, so their marketshares are almost
    negligible compared to the giants like Asus, ECS, and MSI. All it takes is
    for a few enthusiasts to fart the wrong way and Abit's financials are the
    gutter. Making a desirable product isn't enough. Chaintech was smart to exit
    the M/B business.

    And Fatal1ty isn't all a gimmick. The Fatal1ty X800XL is the first retail
    card with factory-backed overvoltage adjustments, the key to successful
    overclocks.
    Which partially negates the benefit of a passive (and expensive) heat-pipe
    solution. Sure, the fans are bigger, but noiseless they aint.

    Yes, back to the primary CPU, of course -- just as it would if the
    physics computation was executed on the second core of a dual-core GPU
    ( or a SPE, in the case of PS3 ), except that the dedicated AGEIA
    hardware would execute faster.
    Sure, after it has been told where to place the 'objects' by the
    CPU/physics algorithms.
    Actually from the case fan ( which is far more useful and effective
    than Abit's noisy, junk OTES )

    Huh ?? <<Factory-backed>> overvoltage adjustments ?? What's the
    difference between that and the normal overvoltage adjustments on
    enthusiast boards ?
    More Abit weasel-words like OTES, uGURU etc... ?
    Ah, but chip-set fans are notoriously unreliable, which is the primary
    reason for the move to passive MB cooling - mostly a function of heat
    and consequent lack of bearing-lubrication. And
    a 120mm 1500RPM case fan is a lot less noisy than a 25mm 6000RPM
    whiner.

    Today's games are not CPU-limited at high resolutions, so designing hardware
    to offload work from the CPU won't provide any gain. And we are assuming in
    future games the CPU actually does most of the physics algorithms, all the
    while nVidia is numerically integrating wave equations on the GPU to
    generate water effects. The more advanced shader programming becomes, the
    more we have to rely on the video card to handle all the flow control and
    load-balancing.

    An AGEIA card would be an ass-backwards solution. If anything the chip
    should be integrated onto the video card, to remove the I/O bottleneck. Even
    then it still needs API-, driver-, and game-support. After all that, it
    still needs to show a tangible performance/quality benefit.
    You don't need a hype-power heatpipe solution to get benefit from case fans.
    The southbridge is near the front fan. The voltage regulators are near the
    rear fan. Transferring heat to the back of the PCB like Asus' new design
    does squat because there's no airflow there.
    Read it carefully, "Fatal1ty X800XL". When was the last time you saw easy
    overvoltage adjustments on a video card? Overclocking and cranking up the
    voltage on video cards is where it counts, since most games are fillrate- or
    shader-limited at the resolutions we want to play at. Even a watercooling
    rig on the video card doesn't do much without the ability to crank up the
    voltage.
    See above. The incremental performance of a heat pipe isn't much compared to
    just plain heat sinks when the sinks are all close to case fans anyway.
    Asus' solution is just as gimmicky as Abit's.
