Graphic Cards The First Quad SLI Benchmarks

Forerunner
X-bit labs have a preview of NVIDIA's Quad SLI system based on two GeForce 7900 GX2 cards. On each GeForce 7900 GX2 is allocated 512 MB of on-board memory, which is connected through a special bridge chip with 16X PCIe lanes to the other daughter card and the system. The two GPUs on the card work in SLI mode. The core and memory are clocked lower than a single GPU card at 550 MHz and 1.2GHz (DDR). For Quad SLI, NVIDIA has introduced a new mode of SLI, AFR of SFR where each card alternately renders a frame split between the two GPUs of one card after the other. The GX2 cards are benched (when possible) at resolution of 2560 by 1600 with 32X SLI AA and compared to a Crossfire x1900 XTX system on a variety of games.

Quad SLI is a joke!

1000$ down the drain :P.

Its only for name sake :|...
Infact its beaten by X1900XT Xfire by quite a margin :P.
Quake 4, too the XFire setup wins.
XFire wins in Splinter Cell: Chaos Theory too...
 
guys its not working optimally ... it will need some revisions and driver updates to be woking at full efficiency ....

here is quote from the article itself

The quad SLI technology indisputably has potential: already now it demonstrates the highest scores in such games as F.E.AR., Far Cry with HDR enabled, scores best high-resolution numbers in Elder Scroll’s Oblivion, it wins Chronicles of Riddick tests, it produces amazing quality with 32xs SLI AA enabled, it does a plethora of great things. At the same time, it crashes in 3DMark05, Far Cry and numerous other games, produces artifacts when SLI AA is activated in Chronicles of Riddick and Serious Sam 2, which all degrades the value of this technology for the user right here and right now.

When ATI CrossFire technology was commercially released in September 2005, we criticized it for its peculiarities (maximum resolution of 1600x1200@60Hz), low scaling and some other issues. At the end, the CrossFire technology has matured significantly, lost its disadvantages and came to stars through the thorns. Can Nvidia’s quad SLI do the same?

Yeah like I mentioned earlier had an opportunity to see this working @ pune.. wasn't impressed then, guess what... hasn't changed:P !!
 
Hmm... not very impressive but hopefully with a couple of driver improvements and maybe with newer nForce 5 architecture it'll improve...
