The BM1387 ASIC Chip

The world’s first bitcoin mining ASIC based on the 16nm process node

Bitmain’s BM1387 chip is built using TSMC’s 16nm FinFET technology and, delivering a record-breaking 0.098 J/GHs, is the world’s most efficient bitcoin mining chip in the consumer market.

Each Antminer S9 employs 189 such chips to deliver more hashrate and efficiency than any bitcoin miner ever made.
