Bitmain Launches More Powerful BM1385 Chip for Antminer S7: Most Efficient Publicly Available ASIC


Bitmain, the bitcoin mining ASIC provider, announced today that it has launched its fourth-generation ASIC, the BM1385. This chip, the company claims, can generate a 45 percent increase in hashrate while needing 50 percent less electricity than its former chip, the BM1384.

“The problem at the heart of designing chips for bitcoin mining is the careful balance of performance with electrical consumption. With lower power consumption, miners have lower electricity bills, or they can increase their hashrate without increasing their power expense,” said the Bitmain chip designer in a statement.

According to the company, the BM1385 can attain 32.5 gigahash per second at a power consumption of 0.216 watts/gigahash-second using 0.66V. This chip was built on the 28-nanometer process of Taiwan Semiconductor Manufacturing Company (TSMC); the company felt that it could outperform chips that were built on 14 and 16 nanometer process nodes that didn’t have full custom design techniques.

Full custom design is an arduous process whereby the engineers have to lay each individual transistor inside the chip. However, while the creation process is more intensive and involves higher risk of
