Bitmain Antminer S19 82 TH/s mining hardware

Bitcoin SHA-256 ASIC Miner

The Bitmain Antminer S19 is a dedicated SHA-256 ASIC miner built for Bitcoin and Bitcoin Cash networks. It delivers a nominal hashrate of 82 TH/s with a tolerance of ±3%. The unit integrates a power supply and is intended for operators who can provide the necessary electrical infrastructure for continuous operation.

RJ45 Ethernet 10/100M Interface

Network connectivity is provided by a single RJ45 port operating at 10/100 Mbps. This bandwidth is sufficient for stratum protocol traffic and pool communication but does not support gigabit speeds. The interface imposes no practical bottleneck for standard mining workloads.

82 TH/s Hashrate at 3250 W

At the rated 82 TH/s the system draws approximately 3250 W with a ±5% variance, yielding an efficiency near 34.5 J/TH. The custom chip design can reach efficiencies as low as 23 J/TH under optimal conditions. Performance scales within the specified temperature range of 5 to 40 °C.
