In June 2016, Bitmain released the bitcoin miner Antminer S9 (refer to: Evaluation on Antminer S9 16nm Bitcoin Miner), which adopted the 189 pieces of the latest BM1387 chips independently developed by Bitmain. The overall hash could reach 11.85 TH/s with 1172W power and 100W/T efficiency. The BM1387 is the 5th generation bitcoin miner chip independently developed by Bitmain, which adopts TSMC 16nm FinFET process and fully-customized designs. The maximum hash of a single chip can reach 74GH/S.
No one ever expected that a classic bitcoin miner Antminer S9 had come into being since then.
