lol no it's not 80% more hash where you get that? a 1080ti is 80% more faster than a 1070 not 1060, maybe you are confusing with the 1080s
i used 2 recources for the comparsion:
whattomine.com
1060 - Ethhash: 21.3 Mh/s
1070 - Ethhash: 30.0 Mh/s
1080Ti - Ethhash: 35.0 Mh/s
https://www.nicehash.com/?p=calc 1060 - DaggerHashimoto: 20.13 MH/s
1070 - DaggerHashimoto: 28.69 MH/s
1080Ti - DaggerHashimoto: 35.00 MH/s
are both pages wong with the Ti?
for my 30 1060 the result is nearly as stated there.
comparing the gpu on the worst algo for nvidia is bad, because the 1080ti and 1080 use gddrx5, which are bad on dagger, comapre it on skein or blake2s or any other algo
