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 R4 employs 126 such chips to deliver more hashrate and efficiency than any bitcoin miner except the Antminer S9.

A Groundbreaking Custom-design Fan

The R4 will change the meaning of a fan for all bitcoin miners

Fans have long been the single biggest source of noise in any bitcoin miner. The R4’s design team found a simple but unique solution to this problem: to do away with the traditional noisy fan!

Inspired by the “fan” of a silent split air conditioner, we designed a fan that can make less than half the noise of the standard miner fan. What’s more is that its speed is automatically controlled to ensure it never creates more noise than is absolutely necessary.

Special-design Control Board to Reduce Latency

The R4's control board uses a dual-core ARM® Cortex-A9 based Application Processor Unit (APU)

Bitmain's in-house engineered control board for the Antminer R4 employs the Xilinx’s ZYNQ-7000 family system-on-a-chip (SoC) that integrates a feature-rich dual-core ARM® Cortex-A9 based processing system (PS) as well as a 28 nm Xilinx programmable logic (PL) in a single device and supports Gigabit Ethernet to ensure that mined blocks are submitted instantly.

  • Hash Rate: 8TH/s (Batch 3) and 8.7TH/s (Batch 4). Variation of ±5% is expected
  • Maximum Power Consumption: 845W +9% (at the wall, with Bitmain’s APW5 PSU,93% efficiency, 25°C ambient temp)
  • Power Efficiency: 0.1 J/GH +9% at the wall (with Bitmain’s APW5 PSU, 93% efficiency, 25°C ambient temp)
  • Noise: 52dB (at a test distance of 1M from the air outlet and at ambient temperature of 30°C in a silent room)
  • Frequency: Automatically set
  • Chip quantity per unit: 126 chips (16nm BM1387 ASIC chip)
  • Network Connection: Ethernet
  • DC Voltage Input: 11.60 ~13.00V
  • Operation Temperature Range: 10°C to 40°C
  • Operation Humidity Range: 5%RH-95%RH, prevent condensation
  • Storage Temperature Range: -40°C to 85°C
  • Product size: 515mm (L) x 100mm (W) x 222mm (H)
  • Package size: 610mm (L) x 215mm (W) x 340mm (H)
  • Package weight: 9 kg
