Sorry if this has been asked already but the thread is 60 pages long.
Has anyone here done any actual testing to see if Titans in SLI will saturate the lanes on a z170/z270 board? Been googling for hours and the closest I could find was an article on techpowerup where they tested a single 1080 in various lane speeds which didn't see any performance hit going from 3.0 x16 to x8. There's been no tests on SLI and pci-e scaling on the pascal architecture at all from what I can see.
Well, there was that test over at
Puget Systems but the results from that was so weird they must have done something wrong, you shouldn't get less performance from more bandwidth, not to mention their lackluster choice of realworld gaming benchmarks. Plus it was an x99 platform where they gimped the lanes in BIOS.
