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 (13.5Th) was produced by Bitmain and released in 2017. This miner consumes 1323W, producing 13.5 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.
