Bitmain Announces New, More Successful 7nm Bitcoin Mining Chip


Bitmain Systems has announced a new 7-nanometer bitcoin mining processor that it states offers new amounts of energy efficiency.

The new ASIC (application-distinct integrated circuit), referred to as the BM1397, is claimed to present advancements in efficiency, chip sizing and energy efficiency for mining proof-of-perform cryptocurrencies primarily based on the SHA256 algorithm, these types of as bitcoin (BTC) and bitcoin income (BCH).

Built working with a 7nm FinFET method from Bitmain chip provider Taiwan Semiconductor Manufacturing Company, the BM1397 will gobble up less electric power than past Bitmain offerings, offering an energy intake to computing ratio “as reduced as 30J/TH,” according to an announcement Monday.

Bitmain states:

“This is a 28.6 p.c enhancement in electricity efficiency in comparison with Bitmain’s past 7nm chip, the BM1391. To accomplish this, Bitmain’s engineering team has thoroughly personalized the chip style and design to optimize its architecture, circuit and economics.

The new ASIC will element in new Antminer mining equipment – the S17 and T17 – that Bitmain claimed it will detail at a afterwards date.

The announcement arrives before long after the mining giant unveiled its most new Antminers – the S15 and T15 – in November, both equally powered by the BM1391 ASIC.

Bitmain also released ASIC miners for the cryptocurrencies zcash and ethereum past year. The growth prompted ethereum’s open-source growth group to tentatively concur in January to implement a new algorithm that would limit ASIC mining on the community, pending even more screening of the required code, ProgPoW.

ProgPoW was delayed before this month, nonetheless, in favor of conducting audits to gauge the performance of the technique.
