The world’s first bitcoin mining ASIC based on the 16nm process nodeOur 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 FanThe R4 will change the meaning of a fan for all bitcoin minersFans 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 LatencyThe 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.Meticulously Designed for Your HomeMega-terahash performance within the space and sound of your home electronicsProducing a sound that’s usually less than 52dB, the R4 manages to deliver a monstrous hashrate of 8.6TH/swith a sound level unseen since the existence of 1TH/s bitcoin miners.With a height of 100mm, it is slim enough to rest comfortably in your book rack or computer table.Ease of UseAntminer’s user interface has been carefully designed keeping in mind the needs of our usersAfter you have accessed the Antminer’s user interface, all you have to do is to enter your wallet address and mining pool settings before you start mining. The user interface also allows you to customize settings such as the fan speed or the frequency and can be upgraded to new releases from Bitmain.
