New Chip Uses the 7nm Semiconductor Manufacturing Process and Will Greatly Improve Power Efficiency

BEIJING, P.R. China, September 21, 2018 – Jihan Wu, CEO and co-founder of Bitmain Technologies Ltd. announced Bitmain’s next-generation ASIC chip BM1391 for mining cryptocurrencies using the SHA256 algorithm at the World Digital Mining Summit in Georgia today. Mr. Wu also revealed that Bitmain will soon launch a new generation of mining machines equipped with the BM1391 chip

The new ASIC SHA256 algorithm acceleration chip carefully built by Bitmain uses one of the world’s most advanced semiconductor manufacturing technologies, 7nm Finfet. The ASIC chip integrates more than a billion transistors and is optimized for maximum efficiency. Thanks to its unique circuit structure and low power technology, it is stable and more efficient.  Mr. Wu said tests have shown that the chip can achieve a ratio of energy consumption to the mining capacity that is as low as 42J/TH.

At his keynote speech at the summit, Mr. Wu said mass production of the 7nm chip will begin and be applied to the next generation of Bitmain’s Antminer machines, improving the new miners in various performance indicators, in terms of power and power consumption, and enabling outstanding performance.

Mr. Wu also pointed out that blockchain technology has continued developing to the present day, noting that the technology’s first decade has seen many difficulties, and that the future direction of development will center around applications of the blockchain.  He said that as applications continue to develop, the industry’s market capitalization as a whole will drive growth.  Exponential growth in blockchain user traffic will at the same time require ever greater capacity in data processing, with hardware acceleration and parallel computing technologies being integrated with blockchain to help solve this problem

Bitmain has been committed to the development and launch of high-performance computing chips.  Since its establishment, Bitmain has independently developed and mass produced a variety of chips.  In 2016, Bitmain took the lead in releasing and mass-producing 16nm chips, applying them to its Antminer S9 miner and other models.  The Antminer S9 quickly occupied international markets with its high-computing power, low power consumption and strong stability, and has become a leader in the global mining machine industry.  In addition, Bitmain’s Antminer series of mining machines has introduced a variety of models that support different encryption algorithms to meet the global demand of different digital currencies.

As a world leading high-performance computing chip company, Bitmain has grown rapidly over the years. It now has multi-brand businesses including Antminer, Antpool, and Sophon. Bitmain’s cryptocurrency mining machine has long been a world leader with a market share of more than 70%.  

The 7nm chip reflects the R&D strength of Bitmain and further consolidates Bitmain’s industry position.  For the entire industry, this not only accelerates the development of digital currency mining but also sets a new benchmark for quality, providing miners with a better mining experience.
