The Test

These SLI systems can pull quite a lot of power, so we employed our 520W and 600W OCZ Powerstream PSUs to put voltage to our parts. We needed to use the 66.81 ForceWare drivers for the Intel system in order to get SLI to work.

Our single card NVIDIA 6600 GT tests were run on the AMD Athlon 64 platform.

 Performance Test Configuration
Processor(s): AMD Athlon 64 FX-53
Intel Pentium 4 EE 3.4GHz
RAM: 2 x 512MB OCZ PC3200 Platinum Rev. 2 (AMD)
2x 512MB PC2-4200 (Intel)
Hard Drive(s): Seagate 120GB 7200RPM IDE (8MB Buffer)
Motherboard & IDE Bus Master Drivers: Intel Chipset INF 6.2.1.1001
NVIDIA nForce 6.31 (Beta)
Video Card(s): NVIDIA GeForce 6600 GT
Gigabyte 3D1 SLI
Video Drivers: NVIDIA ForceWare 71.20 (AMD)
NVIDIA ForceWare 66.81 (Intel)
Operating System(s): Windows XP Professional SP2
Motherboards: Gigabyte GA-K8NXP-SLI
Gigabyte GA-8AENXP Dual Graphic
Power Supply: 520W OCZ Powerstream PSU
600W OCZ Powerstream PSU

The GeForce 6800 Ultra numbers shown in the graphs are included as a reference point from our previous SLI tests, just to show where single card, single GPU performance compares to the 3D1 and SLI solutions. Since the previous tests were performed on an A64 4000+, the numbers are just to be used as a reference rather than a direct comparison.

    1st is the worst...2nd is the best....3rd is the one with the hairy chest :)

    It seems like Nvidia just wants to make sure that none of their partners can benefit from SLI technology to ensure that Nvidia has some new technology to introduce in th future.

    I bet Nvidia already has a multi-gpu card that work on any board and can probably work in SLI with another multi-GPU card sitting in a cabinet somewhere until Nvidia sees fit to let us get our hand on the technology.

    I hope ATI's solution stomps Nvidias into the ground, but then again Nvidias software team cant seem to get it right and they blow away ATI's driver progam which leads me to beleive that ATI will have driver problems as well.
