Calculating Terahash per Watt Performance in Normal vs Low Power Modes

Understanding the terahash per watt performance of your S19 or S19J Pro miners can help you make informed decisions about your mining operations. Here’s a guide on how to calculate it and compare performance in normal mode and low power mode:

Step 1: Determine Your Hashrate

First, you need to know the hashrate of your miner. For Bitmain S19, the hashrate is about 95TH/s (Terahash per second) in normal mode, and for S19J Pro, it’s roughly 100TH/s. When you enable low power mode, these values may vary.

Step 2: Determine Your Power Consumption

Next, determine your miner’s power consumption. The S19 typically consumes around 3,150W in normal mode, while the S19J Pro consumes about 3,250W. In low power mode, the power consumption can be reduced significantly.

Step 3: Calculate Terahash per Watt

Now you can calculate your terahash per watt performance. This is done by dividing your miner’s hashrate (in terahashes per second) by its power consumption (in watts). This will give you a value in TH/W.

Here’s the calculation for S19 in normal mode:

95TH/s ÷ 3,150W = 0.03 TH/W

And for S19J Pro in normal mode:

100TH/s ÷ 3,250W = 0.0307 TH/W

For low power mode, let’s assume the hashrate decreases to 90TH/s and the power consumption drops to 2,750W for the S19. The calculation would look like this:

90TH/s ÷ 2,750W = 0.0327 TH/W

As you can see, despite a slight drop in hashrate, the overall efficiency (TH/W) is improved in low power mode.

Step 4: Compare Performance

Once you have your calculations, you can compare the performance of your miner in normal mode vs low power mode. While low power mode may result in a slightly lower hashrate, the reduced power consumption and improved efficiency mean you’re getting more from each watt of electricity.

Remember, these are approximate calculations, and the exact numbers will depend on various factors, such as your miner’s specific settings, the ambient temperature, and the age of the miner. It’s always a good idea to keep track of your own calculations to understand how your miners are performing.

In conclusion, understanding your miner’s terahash per watt performance can help you maximize efficiency and make the most of your resources, ultimately boosting your mining profits.
