Energy efficiency in mining and its importance. Selecting the operating mode
All video cards can work in economy mode, but they can also be overclocked to the maximum to obtain higher hash rates. Of course, the energy efficiency of mining will suffer.
Not all farms work confidently with all algorithms. Therefore, every serious miner needs to independently check the operation of their cards at the minimum and maximum, and then choose the optimal mode for them, based on the operating temperature and the cost of electricity.

The results obtained can be saved in the form of ready-made links to the 2Cryptocalc calculator, which will allow you to estimate in just a few clicks how much the algorithm you have chosen is better or worse than analogues in terms of the current mining profitability for your farms.
The cost of electricity and the current profitability are key factors in choosing the algorithm and operating mode of the farm.
Maximum energy efficiency and its importance when harvesting new farms
As a rule, all miners sooner or later come to an estimate of the maximum speed per 1 kW of farm power. Someone does this because of the price of electricity, someone – because of reaching the limits of shareware outlets.
The maximum achievable speeds minus devfee per 1 kW of power from the wall on a platinum PSU for the 10xx, 20xx and 30xx series are as follows:
* – data for 30xx are given as of December 25, 2020.
As it is easy to see, the marginal basic income from one kilowatt of energy in the 20xx series is almost everywhere 1.5 times higher than that of the previous one. This is primarily due to the improved memory access algorithm. For algorithms that mainly use the core of the video card, the effect is not so impressive: an increase of about 33%.

Postscript
The whole year of 2021 promises to be very productive in terms of new card models, and with the advent of each new card or miner software, the balance of power may change significantly. Perhaps we will see new mining algorithms – who knows. The article in its current form is relevant at the beginning of March 2021 and will be actively supplemented as new data becomes available.
