....

There is no 1.5 times decrease in consumption there. I watched the tests of cards 1070 devour 180 watts at 460sol well old 280x with the optimization of 185-190watt
....

You compare not optimized 1070 with optimized 280x. In tests I reached about 210-220W power consumption from GTX1070 on Neoscrypt, but it's not optimal
To get 460sol/s from GTX1070 it could tuned at 140W consumption.
The simple example:
28 nm GTX970 gives 290 sol/s at 140W (OC, DV)
16 nm GTX1070 gives 450 sol/s at the same 140W (OC, DV)

The sense of comparing 970 and 1070 if I compare 280 and 1070, and there is no 1.5 difference in consumption, I did not see the 1070 optimization yet, without loss of production, so there is 180watts at 460oils, if the power limit is reduced, then their speed drops, so 1.5 there is not even there 28nm against 16nm
28nm R9 280x 280-300sol 200-210W at 1.250v or 1.170v standart
28nm R9 280x optimizet 330sol at 185W 1.081-1.093
16nm 1070 450sols 180w downvolt? Huh

I do not know cost 500+usd aginist 150usd
So power consumption no big deffierence or 140-160w or 180w
This is my IMXO Wink
