Monero is one of the most lucrative coins to mine when using a CPU, and can also earn some decent money with older GPUs that can no longer mine coins with large DAG files such as Ethereum.
So here is a list of the best GPUs and CPUs to mine monero on, including hash rates and total power drawn.
GPU Hash rates for monero, a mix of all different brands sit at the top.
