I have 2 rigs running currently both using NiceHash on windows 10
6 EVGA 1080 FTW
Running neoscrypt @ 7.02 MH/s
70TDP +50 core +500 memory
Draws approximately 1000 watts and 9 amps at the wall
The 2nd rig
6 Asus 1080ti turbo
Running neoscrypt @ 7.88 MH/s
65TDP +150 core +500 memory
Draws approximately 1150 watts and 9.5 amps at the wall
Interesting. I would have imagined the gap would be much bigger than that. Are you sure you have the 1080Ti's setup correctly? Maybe I do not understand neoscrypt but usually with most other coins the gap is a lot bigger.
EVGA 1080 FTW cards are somewhat higher TDP than "normal" for 1080 cards - 215 watts or some such IIRC, so at 70% they're pulling 150 watts or so per card (which would be 83% on many other 1080 models).
Gigabyte AORUS 1080 ti is 250 watts TDP, at 65% they're pulling 163 watts or so per card.
THAT is why the gap is so small.
