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 Bitmain Antminer S9 Hydro (18Th) was produced by Bitmain and released in 2018. This miner consumes 1728W, producing 18.0 Th/s of hashrate with the sha-256 algorithm, which makes this device almost (if not at all) useless. We do not recommend buying this device for mining nowadays.
