Bitmain CEO, Jihan Wu, has officially announced the successor to its current lineup of crypto mining chips. Titled the BM1391, the chip is one of the first developed to employ the 7nm architecture for extra power at a reduced energy demand.

bitmain launches 7nm chip

Mining operations

ASIC technology remains the weapon of choice for those looking to mine bitcoin and other altcoins. Developed specifically to mine crypto, ASIC significantly outperforms traditional mining hardware including the likes of graphics card and even CPU’s. The new chip developed by Bitmain titled the BM1391, is claimed to contain well over a billion transistors as it was based upon the emerging 7nm FinFet architecture.
Overall, the new mining chip is set to bringing in increased profits for bitcoin miners as the company claims power draw can be as low as 42J/TH contributing to a lower running cost.

Bitmain remains one of the worlds largest ASIC developers ruling the markets with its current Antminer series of which the S9 remains popular around the world. Despite severe supply issues, the demand for crypto has ensured ASIC technology is here to stay !

The benefits of 7nm

7nm has long been a target for chip manufacturers considering the size of the die itself becoming a problem for many. Despite the technology being one of the most energy efficient on the planet, even the likes of Intel have struggled to develop stable 7nm processing chips with many remaining at a prototype stage due to their instability.

To conclude, Bitmain have successfully developed a 7nm ASIC mining chip. To be integrated into the next major mining devices coming from the company. Named BM1391, the chip was revealed recently in Georgia at the World Digital Mining Summit.


Hi I'm Aleppo Allesadero a experienced bitcoin user and educator. Having worked for over a year in the bitcoin journalism ive seen bitcoin grow from strength to strength asserting its power against fiat currency. Hopefully you too can learn about this exciting new prospect which may help transform the way we see finance and economy on a daily basis.
