GTX 1080 will be limited to 2 way SLI

no shit sherlock, nobody makes a 4K 120Hz panel/monitor if no one has dp 1.3+ gpus

after thinking this over, they are obviously just increasing SLI bandwidth by 2x by limiting the configuration to 2x cards.

Each SLI finger can deliver 1GB/s bandwidth (practically it is PCIe Gen2 x1). Now they got TWO connectors, to get TWO GB/s....

 

Which is all fine and dandy, until you realize that todays GPUs, in gaming load, will not be bottlenecked by any serious amount, by even PCIe Gen2 x8.... so if you look at AMDs XDMA (Crossfire over PCIe) you realize AMDs Crossfire has 8GB/s bandwidth availible at Gen2 speeds, and 16GB/s at PCIe Gen3 speeds. Meaning Nvidia is still trailing AMD by 6-14GB/s worth of bandwidth. And i bet the only reason they limited it to maximum TWO GPUs, is because historically, Nvidias scaling (% boost per extra GPU) has been worse then AMDs, and at 3x and 4x it has been absolutely atrocious, more often then not it has been close to zero or even negative effect. Whilst AMDs 3 or 4 card configs has atleast retained minor scaling. Not great, but atleast not negative effect.

 

So this isnt really a large improvement to SLI, it is just a fucking sidestep to avoid having to invent a system similar to AMDs without infringing on their XDMA IP. For which i bet AMD would sue them for infringing upon.

You now need both fingers for 2 way. 

Except that is not correct. You can use both fingers for 2 way and it's recommended but it's not required.

Recent rumours say that the 1080 will use both for 2 way as a higher bandwidth means of doing so

Rumors that have been debunked by people who were at the event. Nvidia recommends but doesn't require it so you can do 3 and 4 way SLI if you want.

[SLIClocker]

Well that means that pascal was not that much of an improvement after all for sli configs. Meaning maybe 4 titan x's would be better at performing in games but then again sli scaling is terrible.

[Weak1ings]

EVGA recalled this statement, Jay was correct and EVGA was wrong...

Facebook comment by OC3D:

" EVGA has since deleted their statement, with Jacob Freeman (EVGA Product Manager) later stating that "More info about SLI support will be coming soon, please stay tuned."

 

Not sure whether this means that  there will or will not be more the two-way.

[SweatyWhiteJedi]

Would it be possible to run 2 sets of 2-way SLI?  say for a Quad monitor setup or something. 

[tr03adam]

WUT. Why are you all crying about it limited to only 2 way SLI? It beats the Titan X in it's home court!

@ALN118 Jay just said this on a facebook post

 

"Everyone complaining about 2 way SLI being only option for 1080, please stop listening to the rumors. I'll explain more at later date" - Jayztwocents

so hes implying this is false?

On his techtalk last night he 100% claimed it was false. Without a doubt in the world. Also he mentioned nvidia was the one suppling the 3 cards for the explicit intent of skunkworks

 

 

This rumor is 100% false and he literally goes in depth talking and explaining it (as far as he can under nda)

what lead evga to believe its limited to 2 way sli?

Pretty much. He keeps saying everyone is spreading false information, and he can't wait to correct everyone lol.

Jayz pointed out the post is no longer on evgas forum. It was a misunderstanding by that particular pr guy. 

[mcraftax]

how over powered do you need your rig?!?!?!?!?

any way. wasn't it to be better to run cards using the new (i think it was) direct x multi gpu thing, linus talked about at some point (i tried to find the video but couldn't)

[Maverick5500]

you all do know that this is not true yes?

Nothing is 100% confirmed as of yet. EVGA did make a statement that the 1080 could only do 2-SLI, but they retracted that statement.

 

Just wait a couple more days until the NDA is lifted so that true benchmarks and information can come out.

[ashtaroth]

Doesnt really matter if true or false. Just think about it. 

 

Even if most people wont go over two cards why limit it to just two? From a business point of view that is killing potential income (extreme enthusiasts). Less cards sold. It will also make a statement that they have the best product. So unless its physically impossible why sell your own product short? 

 

Personally waiting for after NDA and the next big thing. Or DP 1.4 lol

Well, he will be digging his radiator(s).

[kuddlesworth9419]

I'm OK with this. 3 and 4 way SLI is stupid. It never worked with most games and the performance gains drop off after 2 way. It would be nice if we could get perfect support for 2 way SLI though and double the performance of a single card.

[ThinkWithPortals]

Why would anyone do 3-way or 4-way SLI anyway?

[Biggerboot]

Even if this was true, which it doesn't seem it is, 3/4 way SLI is pointless anyway.  Any practical uses that >2 1080s would have in a single system shouldn't be used in one SLI config.  Have two pairs do individual tasks (or one pair and two separate).

 

 

[Texhnlyze]

Can't wait till the NDA lift. This thread is just a shitshow.

[i_build_nanosuits]

apparently this is not even true...the GTX 1080 can be put in 3 way and 4 way SLI.

[Sauron]

I don't really care because I'd never do 3 or 4 way sli, I just don't understand why. Why not just throw the possibility out there? Wouldn't they like people buying 4 gpus instead of 2? I guess optimizing the drivers further would cost them some time, but come on, I don't think they are out of software developers...

2 plai csgo at 8k 240hz just fo' teh sjit nd giggles

 

Anyway, don't you need an i7 Extreme to support 4 GPU'S?

if you want nvidia cards, yeah, but if you go for crossfire you can do it on consumer boards too (there's no minimum pcie lanes requirement, and pcie 3 4x is good enough for any card currently on the market).
