Mining pool f2pool today released a chart of Bitcoin mining machine data, calculated based on current mining difficulty and electricity costs of $0.08 per kilowatt hour. The picture lists a variety of mining hardware models, such as Antminer S19 Pro, Avalon A1366, etc.
The information for each mining machine also includes:
Hashrate/Power Ratio: Indicates the energy efficiency of each device, e.g. 140T/3010W.
Break-even point at different Bitcoin prices: This refers to the price that Bitcoin needs to reach in order to not lose money in mining. For example, if the price of Bitcoin is $57,600, the breakeven point for the Antminer S19k Pro is $56,898.
In addition, each device also shows the electricity cost rate at Bitcoin prices of $56,000, $58,000, and $60,000. These ratios reflect the proportion of electricity costs to mining revenue, allowing one to see how profitable mining is at different price levels. For example, if the price of Bitcoin is $56,000, the Antminer S19k Pro’s electricity cost ratio is 102%.
In general, if the price of Bitcoin is below $58,000, ASIC miners with an efficiency of less than 23W/T per watt will fall into a loss. This means that below this price, the operating costs of less energy-efficient miners will exceed their mining benefits.
