BM1397 - new asic chip from Bitmain for SHA-256 algorithm

On February 18, 2019, Bitmain introduced the second generation of its 7nm asic BM1397 chips for the SHA-256 algorithm. Compared with the current generation used in the AntMiner S15 and T15, the energy efficiency of the new product is higher by 28.6% and is 30 J / Th. Now, we recall, Bitmain sells SHA-256 asik miners with energy efficiency 57 J / TH. Currently, the technical characteristics of the future Antminer S17 and T17 are unknown, but it is not difficult to assume that the hashrate will be 36 Th / s and 29 TH / s, respectively, with the same power consumption. More details about the announcement can be found on the official site Bitmain.
