Optimization

Optimization means getting the same result(or a better one) using fewer resources.

In mining, one of the most important things to optimize is energy efficiency.
Energy efficiency tells you how much power(electricity) you use to produce a certain amount of hashrate.

It is usually measured in W/TH(watts per terahash)

• Watt (W): unit of power consumption(how much electricity the device uses)
• Terahash (TH/s): how many trillions of hashes the device calculates every second

Example

• ASIC 1: 10 TH/s, 200 W. Efficiency = 200 ÷ 10 = 20 W/TH
• ASIC 2: 15 TH/s, 450 W. Efficiency = 450 ÷ 15 = 30 W/TH

Conclusion

Even if the second ASIC is more powerful, it is less efficient because it consumes more energy for each TH.
This means: The lower the W/TH value, the better the efficiency.

How to optimize mining

• Better hardware
  Newer or higher-quality devices usually have lower W/TH.


• Cooling
  Keeping hardware cool improves performance and reduces energy waste.


• Undervolt
  Lowering voltage to reduce power consumption while keeping similar performance.


• Mining software
  Choosing efficient software with low overhead and low dev fees.


• Mining pool
  Selecting pools with lower fees to keep more of your rewards.

Optimization is basically about this: maximize hashrate, minimize costs(especially electricity)
