Description:
ASIC device usually has much better mining performance than graphics card. It is more energy-saving and has a much higher hashrate.
The Canaan AvalonMiner 821 was produced by Canaan and released in 2018. This miner consumes 1200W, producing 11.5 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.
