The GTX 1080 will support higher than two-way SLI

The GTX 1080 will support higher than two-way SLI

The GTX 1080 will support higher than two-way SLI

Over the past few days, a lot of misinformation regarding the SLI support of Nvidia's GTX 1080 has been flying round, leading many to assume that more than two-way SLI with Nvidia's new GPU would simply be impossible. 

We have now confirmed with several sources that this is simply not the case, with one source stating that the GTX 1080 will not only work with Nvidia's new HB (High Bandwidth) SLI bridges but also with existing SLI bridges. This means that traditional 3-way or 4-way SLI bridges can be fitted and work with this new GPU. 

At this time, Nvidia has not released any information regarding any 3-way or 4-way versions of their HB SLI bridge,  which right now leaves many to speculate that only traditional 3-way or 4-way SLI bridges can be used for higher end SLI configurations. 

Right now Nvidia claims that their new HB SLI bridge will offer better SLI performance and scaling than traditional SLI bridges as the new HB bridge will offer double the bandwidth. Right now we do not know how much older Nvidia SLI bridges will limit Nvidia's SLI performance. At this time, we do not know how much older Nvidia SLI bridges will limit Nvidia's SLI performance but it is certainly something that we wish to test in the future. 

We will inform you with more information on the GTX 1000 series of GPUs as it is released.  

You can join the discussion on the SLI support of the GTX 1080 on the OC3D Forums.

I'm assuming that comes from the HB SLI bridges, which clearly use both SLI fingers of a cardQuote

We did have a quote from an EVGA rep that said this. Which really threw a spanner in the works.

EVGA has since retracted the statement below and has confirmed that old SLI bridge designs will work.

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.

Wow EVGA. You'd figure they would at least get there info right seeing as they probably have had the card for a while nowQuote

So I take it from this that performance will be downgraded by using extra cards and non-HB SLI bridgesQuote

What if 2 SLI bridges were used between 2 cards simultaneously? It sure looks like the new SLI bridges are actually just two standard SLI bridges in one - one bridge per connector on the card.Quote
