ASIC device usually has much better mining performance than graphics card. It is more energy-saving and has a much higher hashrate.
The Bitmain Antminer T9 (11.5Th) was produced by Bitmain and released in 2017. This miner consumes 1450W, 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.
