The Multi-GPU Battle: ATI vs. NVIDIA

ATI's recent entry into the multi-GPU market with CrossFire has created competition in both price and performance aspects of high end AMD and Intel chipsets.

ATI continues to have problems with their South Bridges, and thus, they are turning to ULi to supply the South Bridges for motherboard designs based on their new multi-GPU chipset.  ATI's closest partners are currently beta-testing their new South Bridge, but none of them have any confidence in ATI's ability to bring their South Bridges to market in time.  While they are all ready to use ULi based South Bridges if necessary, in order to keep ATI happy, they are continuing to work with ATI's South Bridge in their designs. 

Given the lack of interest in any of ATI's previous chipsets, ATI knows that in order to get CrossFire off the ground with any sort of success, they will need some pretty powerful partners in the Taiwanese market.

Thus, ATI is talking to VIA and SiS to license out their multi-GPU technology so that you will be able to purchase a motherboard based on an ATI, VIA or SiS chipset and be able to run ATI graphics cards in multi-GPU modes.  VIA is particularly interested in this partnership as they aren't the biggest fans of NVIDIA at this point.

First availability of ATI's CrossFire chipsets won't be until July or August time frame from what we're hearing. 

NVIDIA is very curious about ATI's CrossFire, as it will mark the end of NVIDIA's exclusivity on multi-GPU platforms.  In order to help expand the SLI market, NVIDIA appears to be ready to drop the price of their nForce4 SLI chipset.  While currently priced at around $80, the chipset will drop in price to close to $40 later this year.  The goal is to enable SLI motherboards to be priced at $100 or less.  We have even heard that some very aggressive motherboard manufacturers are looking to offer sub-$80 nForce4 SLI motherboards by the end of this year. 

At $80, it would be senseless not to buy a SLI motherboard, which is exactly what NVIDIA wants.

    Can somebody remind us why BTX was so much better than ATX?

    It doesn't look like Intel is throwing its weight about either. Having that strong partnership with Dell you wonder what's keeping them from flooding the world with BTX boards in BTX cases. My guess is Dell is holding back because their profits would suffer because of the high costs of implementation.

    If I remember right BTX was also introduced to battle a few heatproblems. Now that Jamie Oliver cooks meals on a 3.0GHz Prescott, Intel is working on the problem at the source. Sorry about that, Jamie. Much better than throwing a new standard at it.

    I hope BTX takes a long time to take off or better yet that it never does.

    "You can see DDR3 anytime you want. Just put any current Gen Mid-High end Graphics card in your computer...=P

    As far as Desktop use...who knows.
    "

    As explained elsewhere.
    GDDR2 not= DDR2.
    GDDR3 not= DDR3.

    The GDDR3 chips used by 3D graphics card manufactures is not the same as what might be used for desktop DDR3 modules. DDR3 will be by the same commitee as SDRAM, DDR and DDR2. GDDR from 1 to 3 were boutique/custom designs by mem makers with assistance from 3D graphic card manufactures and each design (GDDR, GDDR2, GDDR3) were by different people.

    I want my k8 to have pcie!

    YOu can see DDR3 anytime you want. Just put any current Gen Mid-High end Graphics card in your computer...=P

    So are we ever going to see DDR3? :(

    I say its a great win for AMD. I am glad that they are advancing as much as THAT in just a few months, and I hope that VIA nor SiS die over us... otherwise, that'd leave the market to nVidia only, and we know monopoly is NOT a good thing.

    However, OEMs love VIA chipsets. Heck, we integrators love them too. The warehouse where I buy stuff sells like mofo the Biostar U8668-D, and, as you can guess, its based on the ANCIENT PM400 Pro... but hey, its *cheap*; models for 800Mhz use P4M800 chipset; same goes for AMD K7 and K8 markets: the KM400 is the best selling chipset here in Mexico, suported by ECS/Pc-Chips, and K8M800 is having a real nice penetration in this market. I have not seen a single fellow integrator asking for an nVidia chipset.

    As the article said: costs rule.-

    great arcticle Anand! Keep up the awesome work!

    In Sov...

    Anyways, when I read the tidbit about AMD building on die graphics into a new K8 core, I got goosebumps all over my body. Let the fantasy commense:

    I have visions of them also incorporating that PPU (physics processing unit, if I am not butchering the abreviation).

    Imagine, 2008, which means from now till then, 3 years, at least before those first chips become available, which in my eyes means AMD is already working on said chips...

    AMD Dual Core 65nm,
    On die mem controller supporting DDR2,
    On die gpu
    On die ppu
    All operating at full processor frequency.

    I can't help but think, and I may be dreaming but AMD will put out kick ass graphics...

    I dont care what the name of the chip is
    as long as the VIA socket 939 boards support dual core -- everybody will be happy
    (except for the s754 owners... but they are probably using wishful thinking:P )
