ASIC devices are designated for cryptocurrency mining. They have a much better hashrate to the energy consumption rate and outperforms GPU devices in this regard.
The Bitmain Antminer S9 (13Th) was produced by Bitmain and released in 2017. This miner consumes 1300W, producing 13.0 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.
