Ehh, I'm willing to bet that the device running through the benchmark wasn't the actual Note 7, but could likely be an early prototype of it.
2 reasons.
1) It has an Exynos 7420. That is the same chip that powered the Galaxy Note 5 last year, and judging from the performance scores, it is either heavily downclocked or have some modifications made to it that limits performance. That is very unlikely to make it to a consumer model as each Note iteration has had hardware upgrades over its predecessor. Having a similar-but-gimped processor in the Note 7 won't go well with a lot of people as it will be seen as a downgrade over its predecessor, and given that Samsung has gained a lot of momentum with the success of the Galaxy S7 line, it would be an insanely and unbelievably foolish move to launch the other highly-anticipated device that ends up being worse not only compared to the device it is based on, but also its predecessor.
2) Android Nougat's name was announced, but the OS itself hasn't rolled out of beta yet. Usually, a new version of Android rolls out when the new Nexus devices are unveiled. That has been the case in the past, like KitKat with the Nexus 5, Lollipop with the Nexus 6 and Marshmallow with the Nexus 5X and 6P. Releasing a mainstream device running an unfinished build of Android that is not even fully-finalized by Google is a very risky move, and given that Samsung would also need time to optimize their skin for Nougat, it would be unlikely that the Note 7 would come out to consumers as the first phone running Android Nougat. It would be breaking tradition if it did, but I also think it's a risk.
My initial theory is that the "SM-N930F" used in the benchmark is an early prototype based on the Samsung Galaxy S6 with a slightly gimped Exynos 7420 designed to test builds of Android Nougat in order to test and optimize the software with TouchWiz before it is ready for release.
And here's another theory, one that's actually quite plausible. That is not a Note 7. That's a modified Galaxy S6 with a modified build.prop designed to mimic the Note 7 and having an "Android 7.0" software version.
