1080 TI costs about 800 EUR.
You get a used GTX 1070 from 360 to 400 EUR
1080 TI does 600 sols
we need also 1,5 x 1070 to have 600 sols, because 1 gtx 1070 produces about 400 sols
With this performance, the undeclocked 1080 ti consumes 160 Watt
for the same performance 1,5 1070 about 140 + 70 = 210 Watt
so the difference is 50 Watt an hour, that makes 1200 Watt a day, which is depending on the electricity costs (let's take 0,12 EUR for our example) about 14 cents a day,
which makes in month 5 EUR.
So the for the same performance the price difference is 800 - (400 +200) = 200 EUR
that is about 40 month... just to pay for the price difference... !?!?
Hi thespycry,
Here are some numbers to go through.
The price of 1080Ti founders edition is $699.99 & 1070 is $400
1080Ti out of the box does about 690h/s for the power draw of 250w
1070 out of the box does about 400h/s(I don't have one so used your number)
To get 690h/s you need 1.72 1070 GPUs
Now for power
1080 Ti = 250 * 24 = 6000w = 6kw
1070 = 140 * 24 = 3360w = 3.36kw
1070 Adj for 690h/s = 240.8 * 24 = 5779.2 = 5.77kw
ZEC Production
1080 Ti = 0.0571/day Approx(whattomine data)
1070 = 0.0348/day Approx(whattomine data)
1070 ADj = 0.0571/day Approx(whattomine data)
So in a day with ZEC @ $107/coin it is possible to make
1080 Ti = 6.1097- 0.84(power) = 5.2697
1070 = 3.7236 - 0.4032(power) = 3.3204
1070 Adj = 6.1097 - 0.6924(power) = 5.4173
To get 1080Ti's level of earning(20 cent more) you will be spending $688 instead of $699.99 for 1080Ti a difference of $11.99
Now this is based on the assumption that 1070 will do 400h/s for 140w if not then I don't think 1070 is that efficient.
Hope this helps, If I made any mistake please let me know.
