Some other miners claim numbers that are doubtful. Always make your own research. Keep running the miner on your rigs pointed to your own grin node for a while and see the actual number of shares on grin node. Then compare with other miner. That is the only way how you can be sure about the real graphrate and fidelity.

In our testing, GrinPro has no competition on AMD cards.

Have a good mining.
