How to Find the Hash Rate of a GPU for Mining Ethereum on Windows

I have a laptop with the GeForce GTX 980M on it. I want to find out what my hash rate is to see what my profits could be from mining Ethereum over the Windows platform. Here’s how to do this:

  • Download the latest release of ethminer. Make sure to download theĀ Latest release and not theĀ Pre-release. Unzip it somewhere.
  • Open the command prompt to where you downloaded and unzipped ethminer. Run the ethminer -U -M command:
 C:\Downloads\ethminer-0.11.0-Windows>ethminer -U -M
 Using grid size 8192, block size 128

 min/mean/max: 12570341/12995449/13277536 H/s
 inner mean: 13043122 H/s
  • The inner mean is your hash rate. I’m sitting at about 13043122 H/s, which according to some online mining profitability calculator, could earn me about $30.45 / month if I don’t have to pay for electricity.
