Bitmain Technologies Limited, the Beijing-based owner of the Antminer series of bitcoin miners, Hashnest, Antpool and BTC.com, will launch what it calls the world’s most silent multi-terahash bitcoin miner and a silent 2600W PSU designed for high-performance bitcoin mining.
With these new products, Bitmain seeks to bring bitcoin mining back to homes and continue decentralizing the bitcoin mining network.
Most Power Efficient Chip
The Antminer R4 uses a 16nm BM1387 ASIC chip, which it considers the world’s most power-efficient chip for bitcoin mining. The chip can deliver a hashrate of 8.6TH/s with a power efficiency of 0.1J/GH at a noise level less than 50dB. The noise level is 52dB at an ambient temperature of 35°C.
Bitmain’s in-house engineered control board for the Antminer R4 employs the Xilinx’s ZYNQ-7000 family system-on-a-chip (SoC). The chip integrates a feature-rich dual-core ARM® CortexTM-A9 based processing system (PS) as well as a 28 nm Xilinx programmable logic (PL) in a single device. It supports Gigabit Ethernet to ensure mined blocks are submitted instantly.
