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 L7 (9.16Gh) was produced by Bitmain and released in 2021. This miner consumes 3425W, producing 9.16 Gh/s of hashrate with the scrypt algorithm, which makes this device almost (if not at all) useless. We do not recommend buying this device for mining nowadays.
