An application-specific integrated circuit (ASIC) is a chip customized for mining, rather than intended for general-purpose use (such as GPU). Such a device may provide much better mining performance than GPU.
The Innosilicon A10 Pro ETH (500Mh) was produced by Innosilicon and released in 2020. This miner consumes 960W, producing 500.0 Mh/s of hashrate with the ethash algorithm, which is not one of the best ASIC miners but also not the worst one. This miner can be used to mine MOAC, which seems to be one of the best configurations, in this case, giving the profit of $26.33 daily (assuming electricity cost of $0.10).
Overall, there are better options available in the market. Nevertheless, it may be found at innosilicon.com.
