NVIDIA's GeForce 6 SLI: Demolishing Performance Barriers

SLI Power Consumption
We mentioned before that a strict requirement of SLI is that you have a powerful power supply; in order to further stress our point we performed a few system power tests where we measured peak power consumption of the power supply for our test bed at both idle and load states.
As you can see, at idle and load, two 6600GTs in SLI mode consume about as much power as a single 6800 Ultra. But in SLI mode, two 6800 Ultras require 35% more power than a system with just a single 6800 Ultra.

#18The hardcore gamers would just buy new video cards.

"Nvidia bought the patents, pending patent applications, trademarks, brand names, and chip inventory related to the graphics business of 3dfx."http://slashdot.org/articles/00/12/15/2244256.shtm...

I think 3DFX were bought by nvidia...or at least the rights to the technology....so it is technically the same company...I remember the days of 3DFX scan line interleave....fantastic!bob661 - Tuesday, November 23, 2004 - link
#17Two Opterons would be downright scary if they were limited too. But a 4000 is no slouch. :-) It's still amazing. I happen to agree with #12 but the real test of that theory would be to test slower CPU's and see how the performance scales.

Odd as it may sound, should we be thanking 3DFX for this?http://slashdot.org/articles/00/12/15/2244256.shtm...

Although SLI is exciting, I found myself wanting more info on the Asus board...haris - Tuesday, November 23, 2004 - link
I just had some more thoughts about why SLI/Multi rendering might not be such a great move by Nvidia/ATI.When they launch their next generation cards they are expecting to rake in some extra money from the extreme gamers, right? What happens to that same card when they start purchasing relatively cheap last gen cards instead. This might then lead to something like this: In order for them to get that additional $ during the begining of the next gen card's life cycle they might have to slow down the production cycle of cards to give them more time in the high-end position.

#14... why? You have TWO GPU's here... and ONE CPU. Why is it so amazing that two GPU's can put the squeenze on one CPU? Now... stick a 6800U SLI setup with a couple Opteron 250's with an application that's multi-threaded and THEN I'd be amazed if it was still CPU limited.Aquila76 - Tuesday, November 23, 2004 - link
Or was that 330 Watts the total system usage? (doubtful)Aquila76 - Tuesday, November 23, 2004 - link
What power supply was used in your testbed? If the SLI setup requires at load ~ 330 Watts, I would think you'd need around a 550W unit for your setup.
