NeoS is one of the algos that's memory heavy and has problems with 1080/tis as I've mentioned before. You aren't going to get better speeds then a 1070.
Well, about 30% better actuallyScreenshot. 1070 is getting about 1100 depending on your clocks.
What good is a screenshot if there is a page that is far better than simple screenshot:
http://yiimp.ccminer.org/bench?algo=neoscrypt&chip=387
On there you can see realtime benchmarks of mining 1080 Tis, including their clocks, exact miner version and other infos.
As you can see they are running around 1.6 MH/s at neoscrypt in tpruvot's ccminer 2.2 and that is really about 30% boost compared to 1070, so Schleicher is right.
