Curious about this myself.  As others have mentioned it seems closer to a 1070 card with GDDR5X memory than a 1080 card just with the hash rates on Zec Mining that was shown.

When I was playing around with Eth on my EVGA 1080ti iCX I managed to get 37.7-38.2MH/sec and could push it into 40-41MH/sec range but wasn't 100% stable. Nifty little card indeed if pushing that much, better power consumption as well.  Mine ran with about 88% TDP to get these results.
