Bitmain Announces New 7nm Bitcoin Mining Chip With 29% More Efficiency

On Feb. 18, mining rig manufacturing giant Bitmain Technology announced its next-generation 7nm ASIC chip for mining SH-A2 56 cryptocurrencies like BTC and BCH. According to Bitmain, the mining chip, called the BM1397, is more efficient when mining proof of running( 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 SH-A2 56 -centric chip, the BM1391. The revamped 7nm model ” enables faster and cheaper mining ” and offers a 28.6 percentage improvement in comparison with the BM1391. Bitmain says the BM1397 utilizes low quantities of power and offer an energy consumption to calculating ratio as low as 30 J/ TH.


The chip is constructed utilizing 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 exposed it was fabricating new Antminer models that will be announced at a later date .

The chip announcement follows recent rumors and discussions about the floundering mining ecosystem. Many reports have also detailed company reorganizations with firms like Bitmain, Canaan, and Ebang reaching internal changes. Bitmain says the new semiconductor is evidence of the company’s ongoing commitment to advancing the cryptocurrency ecosystem. The company’s announcement underscores that Bitmain devices let anyone to participate in this fast growing economy.

” The BM1397, one of the purposes of Bitmain’s growing chip portfolio, is designed to bringing a better mining experience and aims to set a new benchmark in ASIC chip technology ” the company notes.

According to the press release, the BM1397 chip will be integrated into the latest Antminer S1 7 and T17 models. Furthermore, Bitmain says the company has new devices that will be announced at a later date.
