All About BTC, LTC, ETH mining as well as other alternative crypto currencies
Time for a quick look at the power usage of the GeForce GTX 1080, the reference design from Nvidia that has a TDP of 180W set by the manufacturer, making it pretty energy efficient for the performance it provides for crypto currency mining. We are checking the situation with the different algorithms apart from Ethereum, because we already know that the GTX 1080 is far from great choice for Ethereum mining.
The GTX 1080 Founders Edition TDP limit of 180 Watt has a power limiter that can give you up to extra 20% increase, moving the slider to increase the maximum available power to be used by the GPU. This can help you get some extra hashrate for the algorithms that max out the 180 Watt TDP of the GPU and as you can see these are actually quite a few. The non reference versions of GTX 1080 should come with higher TDP limits and even higher factory clocks, so they should be able to achieve even more performance as they will be able to keep higher boost frequency of the GPU while mining. Then again you might also want to lower the power limit in order to reduce the power usage and get an even better hashrate per Watt of power used, but for that you might have to also play with the voltage of the GPU for best results and also the clocks.
In the table above you can see that Neoscrypt and Lyra2Re are far from maxing out the TDP of the GTX 1080, the reason for that is that they do not perform that well in terms of hashrate, so some optimizations for them might help give you better performance. Other than that the power usage is high and the hashrate you get is seriously increased as compared to the previous generation of Nvidia GPUs, so performance per Watt for the GTX 1080 is actually great in most algorithms for crypto mining.
