1080 supports 2,3 4 way SLi...the problem is that the HB bridge only works 2-way as of now - sacrificing any other card not getting any bandwidth - -
look at the bridge - a standard single sli bridge is 1/2 that size wide
HB bridge
Duh!! comes to mind here - - ie 4 way sli bridge.... in a 2 way config
makes for double bandwidth
that doesn't stop you from using a dedicated Physx or going double 2-way
if Nvidia was that concerned with bandwidth then make a NVlink connector for the cards or devise new SLI transit protocol..ie sli 2.0
Correct, essentially, they just made it two single ribbons, using both fingers at the same time between two cards for double the bandwidth.
What saddens me is that they finally decide to make some updates to SLI capabilities, and instead of getting rid of the bridge all together like amd did with the 290x, they just limit the cards to two for "high bandwidth" and use both fingers at the same time for sli.
Might give a boost to AMD if you can actually run 3 and 4 cards where the drivers are actually made for it and the 1080 is limited to two.
Also, anyone find it humorous that there are screws missing in that picture?
