RTX4070Ti
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.
