Time for a quick look at the power usage of the GeForce GTX 1070, the reference design from Nvidia that has a TDP of 151W 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 1070/1080 is far from great choice for Ethereum mining when using Windows and we are testing the mining for other algorithms with Windows 7.
Looking at the results from the different algorithms the Nvidia GeForce GTX 1070 Founders Edition does seem to be about 30% on average slower (25%-33%) compared to its bigger brother – the Nvidia GeForce GTX 1080 Founders Edition at the stock settings. The situation with the power usage difference between the two cards is also very similar to the performance difference in the tested algorithms. So the next very interesting question is how well the GTX 1070 will overclock and how will the OCed performance compare to a stock GTX 1080 and an overclocked one. We are going to be posting our results from the GTX 1070 overclock soon, so stay tuned for them.
While we were testing and comparing crypto mining performance we have actually noted that the comparison between GTX 1070 and GTX 980 Ti is actually more interesting as you can see from the table with results. As you can clearly see the GTX 1070 is slightly faster than GTX 980 Ti, but power usage wise it is much more efficient. This can give you a better idea on the evolution of performance and power usage between the previous and this generation of Nvidia GPUs. The GTX 1070 is also a more attractive choice for building multi-GPU mining rigs at the moment as compared to the GTX 1080, though you might want to wait a bit more for the non-reference designs to come out that will allow more serious overclocking and thus even better performance.
