Efficiency

Efficiency (J/TH)

Efficiency (J/TH) is an indicator of a mining device's energy efficiency, reflecting the amount of energy consumed to perform one terahash of computations.

The value is measured in joules per terahash (J/TH) and is calculated as the ratio of the device's power consumption to its Hashrate.

Interpretation of the value:

• A lower J/TH value indicates higher energy efficiency of the device.
• A higher J/TH value means increased power consumption per unit of computational power.

Practical significance:

The Efficiency metric is used for:

• evaluating the economic efficiency of mining;
• comparing different ASIC miner models;
• selecting optimal operating modes (frequency, voltage);
• analyzing the impact of firmware and settings on power consumption.

Impact on operation:

A low J/TH value:

• reduces electricity costs;
• decreases heat generation;
• increases mining profitability at a fixed electricity cost.

Typical ranges:

• ≤ 30 J/TH — high energy efficiency
• 30–35 J/TH — standard efficiency
• > 40 J/TH — low energy efficiency
