I see in image at the top 10 cent power.
By default, many calculators use 10 cents, although WhatToMine was the first. I am sure that the author of the question will solve this problem. The new video cards 4070 and 4080 are still poorly tested in mining and the payback is very high. I would not buy these graphics cards to mine this coin.

Which one is the winner for efficieny while mining NEXApow ?
First of all make sure you have enough adequate cooling as they are all with Gddr6x memory which tend to overheat a lot,you may not see it in the core temperature but the in memory/junction temperature they go up real quick and passing the 100 degree Celsius will slow down your mining and give you some problems to deal with.
Once you have cleared out enough adequate cooling for them,the best option is the 4070 ti as they are cheaper in price and the performance is almost the same compared to the upper cards like 4080 so if you want to build a rig with the 4000 series I recommend you going with this,even lower power consumption is another benefit of this card compared the upper level ones.
The 4090 is a no-brainer here IMHO. Yes, it's a heftier investment, but once you pass that threshold (which is one of the lower if you take a look at the days needed for ROI), you're rapidly accumulating profit.

So if you do have 10 cent power you should consider a few things
1) will nexaPow pay at the current prices.
2) what price will you pay for a 4070ti
the chart says at 10 cent power a 4070ti makes 86 cents a day after paying power.
4070ti cost about 800-900 at Newegg

so payback is 3 years. warranty is 3 years
Makes this a maybe at best

These video cards have almost the same payback, so it's probably better to buy cooler video cards. Use the calculator for more accurate calculations, I do not know the cost of your electricity.But the payback period is very high.
