Bitmain Antminer E3 (190Mh)

The Bitmain Antminer E3 now runs at up to 190 MH/s while drawing 760 W, yielding an energy efficiency of about 4 J/MH and targeting EtHash networks such as Ethereum Classic, EthereumPoW and Ubiq; built as an ASIC alternative to GPU farms, it concentrates hashing power into a compact, industrial-grade chassis whose 76 dB noise level and heavy-duty cooling tell you immediately that it is designed for continuous, high-load operation and therefore belongs in a ventilated, non-residential space or a dedicated rack with reliable power and temperature control. Its strength is clear in lower energy consumption per megahash compared with many GPU setups, but its practical lifespan and profitability are governed in real time by DAG size growth, network difficulty, firmware support and market dynamics; maintaining up-to-date firmware and choosing the right mining pool affect compatibility, stability and effective uptime, while electricity cost, pool fees, block rewards and coin prices determine net returns. Deploy with surge-protected power, active environmental monitoring and plans for noise and heat mitigation, track hash rate and chip temperatures continuously, and model expected revenue using calculators that factor in hash rate, power draw, difficulty trends and fees; also prepare exit or repurposing options if algorithm support wanes, since long-term viability depends as much on software and network evolution as on raw hardware efficiency.

The Bitmain Antminer E3 represents the moment when EtHash mining left the dominion of general-purpose GPUs and ceded strategic advantage to application-specific silicon: its custom ASIC design delivers roughly 190 MH/s while drawing about 760 W, which equates to an energy envelope near 4 J/MH and makes it a purpose-built tool for EtHash chains such as Ethereum Classic, EthereumPoW and Ubiq; architecturally its chips were tailored to EtHash’s DAG layout, a strength that simultaneously created a dependency on the DAG roadmap and on firmware pathways to preserve operational relevance as DAG sizes expanded. In practice this means that beyond the headline hashrate and nominal efficiency, operators must plan for a lifecycle in which firmware availability, periodic microcode or driver updates and community-supported patches determine whether a unit remains productive, and where diminishing returns from aging silicon and increasing DAG footprints require frequent benchmarking and occasional software-level tuning to sustain effective efficiency. The physical design channels significant heat through a compact, industrial chassis cooled by twin high-speed fans that produce a persistent acoustic signature near seventy-six decibels, so deployment belongs in engineered spaces with robust ventilation, dedicated racks, reliable power distribution and surge protection; continuous telemetry on hash output, per-chip temperature and fan RPM is essential to preempt thermal throttling and to time maintenance actions such as fan replacement, dust clearance and firmware flashing. Commercially-minded operators should treat the E3 as a finite, mission-focused asset: model expected yield not only from hashrate and power draw but from network difficulty trajectories, pool selection and fee structures, reward schedules and probable resale or repurposing pathways if algorithm support erodes, and embed contingencies - from contract-level exit clauses to hardware redeployment plans - so that the device’s mid-term utility is governed as much by strategic foresight and operational discipline as by its raw joules-per-megahash metric.

Etchash ist eine kryptografische Hash-Funktion, die als Rückgrat von NiceHash Proof-of-Work-Konsensmechanismus. Dieser Algorithmus verarbeitet Eingabedaten beliebiger Länge und erzeugt einen festen Hash-Wert, der Sicherheit und Integrität im Mining-Prozess gewährleistet.
