Has anybody ran benchmarks with the new SLI bridges and compared them to the standard bridges?

Will there be more standard looking bridges with the new spec coming out?
 
I suppose that is a good reason why we haven't seen any, however I would have expected a review site or two to have one by now. The card has been released for over a week now.

Your testing is interesting, but doesn't really give an indication on what if any benefit the new spec bridges will bring. Hopefully we'lll see them released soon.
 
They're not even out? I ran some comparisons between single SLI finger versus two here:

NVIDIA SLI HB Bridges and Pascal GTX 1080 SLI Performance

I remember using flexible sli bridges to connect 3 video cards back in the day. Someone correct me if I am wrong. But I don't think they would actually physically connect 2 fingers. Pretty sure the connections go from bottom to middle, and middle to top, and one connection from bottom to top. So electrically, with old fashioned sli bridges. You can't connect both fingers. You would have to use 2 single flexible sli bridges to do this test.

Well, there are the fingers and there are the speed differences between the newer LED bridges and the old ribbon cables. If you try to use a ribbon cable-style bridge with a 1080 today you get a performance warning.

Either way. I don't think you can conduct the test he performed using a tri-sli bridge to do dual sli. You will only get a single connection, not two.

I'm wondering the same thing. What's taking so long for these bridges to come out, it's like they are still in production or something. I've been trying to pick on up for my new rig.
 
Using the ribbon SLI bridge for now until the new 1080 SLI bridges come out. But it looks like it doesn't even matter according to the review above, the drivers havent fully supported them anyway...

I have a feeling it might help minimums.
 
Has there been any notification from nvidia or any retailers about the availability of the new SLI HB bridge? Its really odd that its been 3 weeks since release and still no bridge...
 
Nvidia is probably deliberately holding back because SLI performance is still terrible or non-existent on the new cards. The few benchmarks I've seen show a lot of unsupported apps or bad frame-times.

Looks to me like the HB bridge is just two regular SLI bridges side-by-side. You could probably get the same effect if you happen to have an extra bridge lying around.

Yeah, something isn't right here. I've been keeping my eye on these things for my new rig and nowhere to found yet.

I doubt it's that simple. Those bridges have been out since last year (two finger connection). No difference in one finger versus two finger in this pic, performance-wise.

Oh you actually are running SLI! How is it working for you so far? I'm debating on picking up a second 1070 or whether to trade up to a 1080.
 
SLI seems buggy for me so far, in Overwatch I get stutters from 160+ frames to 50-70 every minute or so with SLI on with Epic settings at 1440p. With SLI off I get no stuttering at all. Fallout 4 / Witcher 3 / HOTS play with no issue with SLI on however.

I'm using a 3 way SLI bridge at the moment, waiting on that elusive SLI HB bridge...

is that a ribbon type? i'm just about to order an LED type bridge, wondering if i should even bother or just make due with a ribbon type until the HB bridges are released. I want to be able to run 2560x1440 144 fps in 2 way SLI....not sure a ribbon type will work. i don't have my cards yet so i can't check myself.

SLI generally shines at lower FPS (< 90ish). Some games you'll need to turn SLI off for, which you can do per application. DICE usually has very good SLI scaling. Witcher 3 has really good SLI support. Generally the games without support you dont' need SLI for anyways.

No different than my TITAN X SLI in terms of issues. Using the newer, two-finger, LED bridge above. I haven't used ribbon cables for years. Waiting on the HB bridge.
 
So I just ordered 1080FE #2. I only have one of the rigid single finger, as described above .. old 2 way bridges from NV. Will this suffice at 3440x1440 until the NB bridges surface, or do I need to find one of the old 2/3 way bridges?

The link posted above shows there's little to no difference between the single finger or two finger LED bridges performance-wise in 2-way SLI.
 
Which are electrically the same as th old style.

That may be true but if you scroll up further in this thread you can see performance differs as you get to higher bandwidth. Old bridges are slower, then LED, then the new HB bridge.
 
It doesn't make sense that they could be electrically identical yet differ in performance, though. So either they're not electrically identical, or they have the same performance and Nvidia is just trying to get ppl to spend money on a new accessory.
 
Ugh, I ended up buying the 3 slot, and noticed I needed the 4 slot. Hopefully they'll ship both even though they say limit one per person

Pretty sure it's one of each per person - so you should be fine.

The LED bridges from Nvidia can be overclocked to 650mhz.

At least now people will be able to do an actual sli review on the new bridges. My whole point was that the review was most likely using flawed methodology.
 
Definitely. Come Monday I'll be able to see if it was all a gimmick or reality. I'm around 9400-9600 for Firestrike Ultra, and The Witcher 3 seems to be getting terrible framerates @ 4k with every option on (~35-50 fps).
 
I'm running Witcher 3 at 3440x1440 max settings ( even Hair works) on 2 EVga GTX 1080s IL SLI and I'm getting 80fps to 100 fps coupled with a intel 6850k@4400mhz and Msi x99a gaming Carbon Mobo. I hope the new sli bridges improve it more.
 
Well, the new Hybrid SLI arrived, and I installed and ran a few benchmarks. Overall, I'm disappointed. My 3dMark score actually went down with the new bridge. I ran it about 3x and was getting about 9000-9200 on Firestrike Ultra whereas with the ribbon, I was getting about 9400-9600. On The Witcher 3, running through a stressful area, my framerate is up though. With the ribbon, I was getting anywhere from 34-46 fps (every option on and maxxed @ 4k, which includes AA as well as max hair works). With the new bridge, I was getting 39-55 fps. The average was 38 fps on the ribbon and 42 fps with the new bridge. Just remember though, these are only a few quick tests, so there could be some influences to tilt the framerate in one direction or another.

*EDIT*

New Bridge: I scored 9 071 in Fire Strike Ultra
Old Bridge: I scored 9 461 in Fire Strike Ultra

Interesting. That sounds similar to my experience with the LED bridges and using one finger versus two finger configuration.

Firestrike Ultra should be a good test since it's 4K...crazy that you did no t see any benefit. My bridges show up this afternoon sometime.
 
Curious about the differences you guys see with the new bridge. Going to tell me if I should spend the money for one or keep my single EVGA LED one.
 
Holy cow, that was fast. Mine just got the label printed, hasn't even shipped. Second card incoming Wednesday!

The throughput is probably slower. People have complained about the frametimes with SLI for a long time, so maybe NVIDIA is focusing on the quality of frames presented rather than pure speed. The higher frames in Witcher 3 is probably a side effect of sync and utilization being higher with the new bridge. I'd really like to see some FCAT results between the old bridge and the new. Hopefully Guru3D will step up to the plate.
