GPU devices are very popular in mining cryptocurrencies but the ASIC devices usually outperforms them in many cases. The ASIC device usually consumes less power and has better hashrate.
The StrongU STU-U6 was produced by StrongU and released in 2019. This miner consumes 2200W, producing 440.0 Gh/s of hashrate with the x11 algorithm, which is not one of the best ASIC miners but also not the worst one. This miner can be used to mine ARC, which seems to be one of the best configurations, in this case, giving the profit of $11.66 daily (assuming electricity cost of $0.10).
Overall, there are better options available in the market.
