I made some tests on 1050 Ti with cudaminer v1.0.0 using the --mode 2 option which gives the best results, also i have reduce TDP to 58W and the hash rate is about 450KH/s, i was expect from this card to do about 520KH/s on 55W, but ι failed to my calculations.
Changing SM_50 to SM_52 i think gives more stable hash rate.
My GTX 1060 goes from 715KH/s @ 90W to 505KH/s @ 60W. The memory bandwidth per stream processor is about the same for GP106 and GP107, so the difference is probably due to better power efficiency of 1060 at half the rated TDP.
