Three-Way SLI Will Not Work on G92 8800GTS

zekrahminator · Dec 4, 2007

While the G92-based 8800GTS is on track for a December 11th release, and NVIDIA three-way SLI will be released at a similar time, neither will be compatible with the other. It would seem as though NVIDIA is trying to keep three-way SLI an exclusive club for the more expensive offerings from the graphics giant. At this point, only the 8800GTX and 8800Ultra are confirmed to work with three-way SLI, and there is the possibility that the 8800GT will be able to use three-way SLI. While three-way SLI may be possible through software rendering at some later point in time, chances are it will be slow and buggy. The main giveaway for the lack of three-way SLI is the lack of a second SLI bridge connector on the 8800GT.

Well, as long as I can use a third card for physics, I'm happy.

So that's why they're keeping the 8800 gtx/ultras...

I gues if your gonna go ... go all the way. man your gonna heat up your room so quick. ihad a 2900 and went back to a 1900 because of money issues (had to sell) and they heat up my room like a mr. heater.

That will be the only reason anyone will buy a GTX/Ultra. Especially when you can buy the GT's and HD3870's less than half the price....

Its a bit of a cop out by nvidia Imo, they know that the $800 GTX/Ultra cards are not going to sell, because of the better performance and price of having 2 mid range cards, ie. GT, GTS etc...

Whinging aside, I can't wait to see some benchies with 3 ultra's churning away!!!

is it true that tri sli doesnt scale as well as crossfire ex?

erocker · Dec 4, 2007

Awesome! Nvidia should just keep hyping triple sli, and keep releasing cards that don't support it! Why in the hell don't they fix plain ol' regular sli first?!

Because if NVIDIA didn't screw up at some point, we wouldn't see a startling come-back on ATI's part

in general, yes.

Now if ATi could just find out a way to get 2 of thier cards to work in an SLi chipset. That would be a comeback and a spit in the eye for Nvidia.

And what flavor of processing power would one need to not bottleneck the hell out of tri-SLi?

Well, I'm afraid you cannot. Untill there is some sort of proof and means none of us will transform our video cards into ppu's. I'm quite sure cpu's can handle physics anyway.

It doesn't matter. I'm sure a decent quad core or a high-flyin' dual core can handle it. Sli scales pretty poorly and I doubt adding another card to the mix will make it any better. Perhaps 3 Ultra's could bottleneck a 3ghz quad core.

Wait, so it IS possible on the 8800 GT, but NOT on the 8800 GTS (G92)??

i think zek just likes the write "three way."

I said this almost a month ago...

The new GTS was never mentioned to be supportive.

Ultra remains because of resolution and TRI-SLI.
