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 Innosilicon T2 Turbo 25T En.Sav. was produced by Innosilicon and released in 2018. This miner consumes 1360W, producing 20.0 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.
