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 makes this device almost (if not at all) useless. We do not recommend buying this device for mining nowadays.
