8x vs 16x makes no difference when using 2x 1080ti.
We've known this for years, the 2080ti is starting to show SOME difference but it's still very small.

Noticable difference exist even with GTX680 in SLI between x8 and x16. Sorry, but Steve don't know SLI

Doesnt nvlink solve some issues with sli as from what i've read its not the same tech?

There is a difference in cards that predate the HB bridge or NVLINK because the old bridges didn't have enough bandwidth and SLI was using the pci-e bus instead, but you won't run into that with 1080ti's on the HB bridge or 2080ti's with NVLINK.

A pair of 2080ti's that aren't using pci-e for SLI framebuffer transfers doesn't need more than x8 pci-e 3.0 each

The test was done with a newest HB bridge to the day the video came out, not a flex one or one of the older. In the video are 680, 780Ti, Titan X Maxwell and 1080, if you did not want to see it.

I looked at that video before commenting, it doesn't mention the HB bridge anywhere at all in the video, description or comments and the performance shown is in-line with the older bridge setup

Edit: they also say "Archival test, carried out before the change of the CPU from i7 5930K to i7 6950X" and the 6950X came out before the HB bridge

It doesn't say in the video but they refer to it in here at 3:40ish
it's in polish so I believe you will not understand a word. But they use the newest and the best bridges to the day of any test. But I believe you noticed the video I linked first came out in september 2017 so waaaay after HB Bridge release.

Always enjoy this guys videos. One of the few people I trust on Youtube.


1080 Ti SLI>>>>2080 Ti @ 4K in SLI games, but that was kinda a given already. Multi-GPU supported games like SOTTR really struts its stuff. 2080 Ti does hang close to the 1080 SLI setup though.

2K res definitely bottlenecks 1080 Ti SLI & something I noticed too when I had a Titan XP setup (until I went 4K)

They say themselves this was an archival test performed before they changed to the i7 6950X (which launched before the HB Bridge) and the performance loss on their video is similar to the gain you get going to the HB bridge on a 2x8 system like the 6700K used in this test:
