On Feb. 18, mining rig manufacturing giant Bitmain Technologies announced its next-generation 7nm ASIC chip for mining SHA-256 cryptocurrencies like BTC and BCH. According to Bitmain, the mining chip, called the BM1397, is more efficient when mining proof of work (PoW) coins and the new chips will be installed in the latest Antminer series of devices.
The Next Generation 7nm Chip From Bitmain Technologies
Bitmain has announced a new mining chip that claims to be more effective than the semiconductors the company manufactured in the past. The new BM1397 chip is the successor to Bitmain’s previous SHA-256-centric chip, the BM1391. The revamped 7nm model “enables faster and cheaper mining” and offers a 28.6 percent improvement compared to the BM1391. Bitmain says the BM1397 uses low amounts of power and provides an energy consumption to computing ratio as low as 30J/TH.

“To achieve [better efficiency], Bitmain’s engineering team has thoroughly customized the chip design to optimize its architecture, circuit, and economics,” explains the company’s press release. It continues:
The chip is made using TSMC’s 7nm FinFET process — The BM1397 is a testament to Bitmain’s improvements in chip design methodology and deep understanding of the most advanced semiconductor fabrication technologies.
Bitmain also revealed it was manufacturing new Antminer models that will be announced at a later date.
