Bitmain launches new 7nm ASIC chip for bitcoin mining

Bitmain, the crypto, blockchain, and AI development company, today announced its next-generation 7nm ASIC chip, BM1397, which achieves new benchmarks in performance, chip area and energy efficiency for mining cryptocurrencies such as Bitcoin (BTC) and Bitcoin Cash (BCH), that use the SHA256 algorithm for their Proof of Work (PoW).

The new BM1397 chip requires lower power and can offer an energy consumption to computing ratio as low as 30J/TH. This is a 28.6% improvement in power efficiency in comparison with Bitmain’s previous 7nm chip, the BM1391.  To achieve this, Bitmain’s engineering team has thoroughly customized the chip design to optimize its architecture, circuit, and economics. The chip is made using TSMC’s 7nm FinFET process.

The BM1397 showcases Bitmain’s improvements in chip design methodology and deep understanding of the most advanced semiconductor fabrication technologies.

Today’s announcement follows Bitmain’s on-going commitment to the development of high-performance computing chips and is a part of its aim to help advance the cryptocurrency ecosystem. Bitmain’s innovations enable anyone, anywhere to mine and benefit from cryptocurrencies. The BM1397, part of Bitmain’s growing chip portfolio, is designed to bring a better mining experience and aims to set a new benchmark in ASIC chip technology.

Founded in 2013, Bitmain transforms computing by building industry-defining technology in cryptocurrency, blockchain, and artificial intelligence (AI). Bitmain leads the industry in the production of integrated circuits for cryptocurrency mining, as well as mining hardware under the Antminer brand. The company also operates the largest cryptocurrency mining pools worldwide—Antpool.com and BTC.com. Bitmain technology supports a wide range of blockchain platforms and start-ups.
