GTX 1080 does not support 3/4-way SLI

[IllogicalGlory]

Hi Everyone,

We can confirm that 1080 cards only support up to 2-way SLI and anything above this will not work, no matter the SLI bridge. Please however keep in mind that if you do use the new SLI bridge along with two 1080 cards, then it gives more performance than 2-way SLI did in the past on previous series.

99.9% of us don't care, but I do feel for those few who always bought 4 cards.

On the plus side, the performance of 2-way SLI will be better than before thanks to the new bridge.

That kinda sucks. Lets hope dx12 mgpu gets going either way.

I wonder how quad gtx 980ti/titanx owners are feeling? I bet they are tempted to skip small Pascal until we see that SLI 1080's are about as fast or faster in certain games. Tough decision...

i hope they do.

seems like an unnecessary upgrade for them..

I'd assume they would be waiting for the big dogs to show up regardless.

It's a mainstream card, like I said in the other thread, so that's not surprising (and why I think it's overpriced).

We saw users drop their 780 ti's for 980's until the 980 ti was released. Some enthusiasts need the fastest all the time.

It still matters for dual-GPU users:

1) Additional cost of SLI HB bridges not included in almost any current boards.
2) If you carry over new cards to a new mobo should you upgrade and the mobo has a different arrangement, you need a new bridge depending on the spacing of the new mobo you get.
3) Possible interference with certain AIB cards. Could this be a way for NV to push people even more into FE level cards that were designed to be a "perfect fit" for these new SLI HB?
4) Stuck at 2GB/sec vs. 16GB/sec for AMD. The minute PCIe 4.0 is introduced, AMD's available bandwidth grows to 32GB/sec.
5) 1070 is still limited to old 1GB/sec 1st gen SLI bridges. Why such an artificial limitation to further GIMP 1070 SLI? I mean if 1080 is only 25% faster than 1070, wouldn't it stand to reason that if 1080 SLI requires SLI HB bridge that 1070 SLI would also benefit from them? AMD's CF bridges already limited HD7970GF beyond 2560x1600 and they were 0.9GB/sec. This means 1070 SLI will never extract its full potential with 1st gen SLI.

I covered most of these points here.

Honestly, NV is just making reasons to charge us more it feels like. First reference cards magically go up by $70-100 and now we need new SLI HB bridges when XDMA is free.

I wonder what this will do for people chasing records in things like 3DMark. Scaling issues will obviously be present with 4 GPUs, but quad P10 might actually be faster than dual 1080 which would lead to the almost unheard of situation where AMD is on top of the 3DMark charts.

This is a pity for those who would want 3 or 4 cards.

Yeah, poor things

This is interesting from a technical perspective - why would this limit exist, in particular when Nvidia should be interested in selling as much of these cards as possible?

Without having numbers, I would guess its less than 1000 cards that is sold as GPU number 3 and 4.

The entire concept of SLI and Crossfire is on the verge of death anyway with multiGPU support fading out.

Huh? What are you smoking?

DX12 includes implicit and explicit multi adapter support. Multi GPU is getting easier, more reliable, and more popular.

How many of the released DX12 games support multiGPU? Isnt it only that benchmark game?

Really not that many DX12 games released at the moment.

I'd love more evidence for your assertion. Can you provide statements from any of the major industry players proving that it is on its way out?

Microsoft? AMD? Nvidia? Khronos?

Any game developers saying they won't support it anymore?

Anything?

Why dont you tell me what future DX12 games that will support it. Since you dont want to talk about the current released games

You are the one that made the assertion, you back it up. Provide proof for your assertion or you are just trolling.

Not making fun of him. He's a great guy who has helped me with tech advice.

 

[cytg111]

With 1080, VR and multiprojection, at least 2-way SLI is not going anywhere.

Well, he is problary gonna be, down the road at least, when he doesnt have to deal with the headaches of 3 and 4 way sli/cf

[LTC8K6]

So maybe they will have special editions for $100 more with 4 way SLI capability?

Or maybe with the new connector and the higher bandwidth, 4 way SLI just won't work?
