Benchmarking

Ethminer can also be used to run benchmarking, as shown in the following screenshot. Two modes can be invoked for benchmarking. It can either be CPU or GPU. The commands are shown here:

• CPU benchmarking:

      $ ethminer -M -C    

• GPU benchmarking:

      $ ethminer -M -G

The following screenshot example is shown for CPU mining benchmarking:

The GPU device to be used can also be specified in the command line:

$ ethminer -M -G --opencl-device 1  

As GPU mining is implemented using OpenCL AMD, chipset-based GPUs tend to work faster as compared to NVIDIA GPUs. Due to the high memory requirements (DAG creation), FPGAs and ASICs ...
