NVIDIA's GeForce 6 SLI: Demolishing Performance Barriers

Half Life 2: AT_coast_12
The at_coast_12 benchmark begins to show GPU limitations earlier on in the resolution scale than the previous two tests; at 1280 x 1024 we start seeing some performance benefits to SLI, but the real win once again comes at 1600 x 1200. At 1600 x 1200 the 6600GT, once paired up in SLI mode, enjoys a 44% increase in performance which allows it to outperform a single 6800 Ultra by 10%. SLI mode also allows the 6800GT and 6800 Ultra to both achieve 100+ fps frame rates in this benchmark.
With AA/AF enabled all of the cards do extremely well; the 6600GT SLI configuration ends up being faster than a single 6800GT/Ultra, and the latter two cards manage to remain mostly CPU limited at resolutions up to and including 1600 x 1200.

#33I found one here.

I don't know if they actually have one in stock though.

Where are they getting the 6800GT PCI Express cards? I can't find them anywhere...are they even out yet or are these just review boards?L1FE - Tuesday, November 23, 2004 - link
#28 If the nextgen video cards are also SLI capable, then SLI offers even more performance for a new GPU launch. If you don't want SLI that's your choice, but SLI offers consumers a wider range of choices just because cominations now make it that much more complicated. Whether that's a good or bad thing is yet to be seen, but I like how it makes things exciting between new GPU releases.T8000 - Tuesday, November 23, 2004 - link
Altrough it is nice to see Nvidia take PC gaming quality one step further, these solutions are more expensive than ever before.But where does this money come from, you ask. Well, since CPU's are stuck at around 3 Ghz (or almost equal) for some time now, people look for other upgrades to buy.
And SLI is an easy way to explain that a top-end GPU solution now costs $1000 instead of $500, because it now contains two $500 cards.
But since SLI is much cheaper than pre-overclocked (Falcon/Alienware) solutions, it is currently worth its premium for a lot of users.
It also creates an interesting problem for ATI, to sell technology that is way behind for lowewr prices or to copy the SLI concept, hoping that their users are willing to wait.

#28 the next gen of both nVidia and ATI will be only a tiny jump over the current generation. We won't see another big jump until DX10 has been out for a while. The next jump will be a 9700 to 9800 style jump, if that.http://www.anandtech.com/news/shownews.aspx?i=2340...

Yeah, where is 8xAA/16xAF. I want that tested. I mean with all that power, who wouldn't want to see the results of the fabulous 8xAA IQ.FICo - Tuesday, November 23, 2004 - link
So does Nvidia now want everyone to buy 2 of their cards? I really hope its not popular. They should just design faster GPUs rather then relying on such a sledgehammer approach. Nvidia seem to bring out new GPUs once a year, and updates 6 months into a products life. So the new "Geforce 7" chip will be out end of spring time next year. Of course the performance of a single card "GeFroce 7 Ultra" will be a big jump as usual, and will most likely out perform todays PCs with dual 6800 Ultras. Nvidia's SLI technology is certainly interesting, shame its such poor value for money. Surely a dual core approach would be cheaper for the public to buy, yet still offering extra performance.Filibuster - Tuesday, November 23, 2004 - link
Dual Voodoo2 cards is what, 200Mpixel/s? :)Jeff7181 - Tuesday, November 23, 2004 - link
Thinking about it more, I think I'd rather just see some 32 pipeline GPU's with 512 MB of RAM and it's very own nuclear reactor to power it :)Souka - Tuesday, November 23, 2004 - link
Anyone want SLI cheap? don't even have to upgrade your moherboard.....For sale.... two 8mb 3dFx Voodoo2 boards wih SLI cable...PCI interface of course..... it rocked in the 90's....why not now?
