Nvidia GeForce GTX 1080 and Ethereum Mining, What to Expect

  • The brand-new Nvidia GeForce GTX 1080 (Pascal-based) video production cards have actually been available for concerning two weeks now and also we have actually ultimately managed to get one certain GTX 1080 to perform concerning experiencing it and see exactly how really good it executes for crypto crurrency mining. We are starting experiencing Ethereum as the currently most well-liked altcoin for GPU mining and nevertheless the GTX 1080 does not do excellent for ETH mining.

    You should formerly understand that Eehereum is a lot better on AMD GPUs than on Nvidia and the brand-new Pascal GPUs such as the GTX 1080 do great both in order to there are some interest in them on Windows for the minute.

    The GTX 1080 cards are utilizing quicker in terms of clock speed GDDR5X video clip memory that may do superb for video gaming, however apparently it does not do wonderful for memory intensive algorithms this kind of as Ethereum. In reality it appears that the GTX 1080 is slower simply due to the GDDR5X than the GTX 1070 that uses typical GDDR5 video memory, when you include the huge value of the 1080 it is most absolutely not very good option for Ethereum mining like it could be for pc gaming.

    We have compiled a Windows binary of the latest pre-release of Genoil’s ethminer 0.9.41 fork version 1.1.3 (source) with CUDA 8.0 and Compute 6.1 that is used by the new GTX 1080 and GTX 1070 to test with and you can find a download link below. So let us get to the hashrates you can expect from the GTX 1080 by mining under Windows and then from Linux.

    If you are using Windows 7 or 8.x you will notice that with the default settings the miner will crash when trying to load the DAG file into the video memory of GTX 1080, regardless if you are using OpenCL or CUDA mode. Other OpenCL only miners such as qtminer will also fail with a driver crash, this is a driver issue and even if you manage to not crash the driver you will get a disappointingly low performance. You can run the Genoil CUDA fork of ethminer in CUDA mode with the -U option and add the following parameters --cuda-grid-size 2048 --cuda-block-size 128 to prevent the driver crash, however you will be getting less than 1 MHS in terms of hashrate, so pointless.

    If you move to Windows 10 the situation is slightly better, but not that much actually. With the latest video drivers 368.39 for Windows 10 you will be able to mine Ethereum, unlike on Windows 7/8.x, but the hashrate you will get is still going to be disappointingly low at just about 4-5 MHS. Again a driver issues, however there is a talk about an upcoming driver update that should fix the problem of low hashrate at least for Windows 10 that is expected sometime next month (we cannot confirm this however).

    So the only thing that is left to do if you already got a GTX 1080 GPU or more than one and want to mine Ethereum with it is to go for Linux. Under Linux people are reporting about 23 MHS on average as hashrate for mining Ethereum on GTX 1080, a speed that is a bit higher than what you can get from GTX 970, GTX 980 or GTX 980 Ti, but still a bit disappointing compared to what you can get from high-end AMD GPUs.

    The GTX 1070 that we already mentioned is doing better for Ethereum should be capable of around 27 MHS under Linux (in Windows they apparently have the same low performance issues for the moment), though we have not yet been able to personally verify that. So even with the low power consumption
