Bitmain Antminer S9 Vs Antminer S19: What’s the difference


In this article, the Antminer S9 and Antminer S19 from Bitmain will be compared in terms of their features, hashrate, energy efficiency, and profitability.

The Antminer S19, which was first made available in May 2020, and its various submodels probably contribute the most to the total hashrate of the Bitcoin network of all the mining rigs currently available. Thousands of S19s have been purchased from Bitmain by major publicly traded mining companies like Marathon Digital Holdings, Riot Blockchain, and Argo Blockchain, and they are also very well-liked by our Mining Store customers and more casual miners in Europe and North America.

After the S17-series mining machines from Bitmain experienced extremely high failure rates (20-30%), the S19-series has generally been viewed as a great success. Hardware efficiency increased from 40+ W/TH with Antminer S17’s to as low as 29.5 W/TH with the S19 generation. Failure rates for S19’s are reportedly below 2%, and if purchased new from the manufacturer, they come with 365-day warranties.

As Bitmain’s most recent series, S19-series offers significantly better performance than S9 does.

Let’s examine these two miners in more detail.

About Bitmain

The most renowned manufacturer of mining equipment, Bitmain was established in China in 2013 and now has offices in a number of different nations. The business created the Antminer, a line of ASIC miners made specifically for Litecoin, Dash, and other cryptocurrencies.

You know you’re in the right place when “Bitmain” is mentioned in relation to a device or chip you’re thinking about purchasing. Bitmain has established itself as the market leader for mining rig chips. According to some estimates, it controls 80% of the crypto mining market, which is a sizeable portion. Have you ever heard of Antpool or Bitmain is also the owner and operator of two of the biggest Bitcoin mining pools.

Antminer S19

Bitmain Antminer S19

The Antminer S19 was first released in It is the base model of the Antminer S19 series and the most popular variant produces 95 terahashes per second (TH/s), though there are S19s that range from 84 TH/s to 95 TH/s. The 95 TH model uses 3250W of power and operates at a 34.2 joules per terahash (J/TH) efficiency.

Antminer S19 Profitability

The Antminer S19 can earn its owner $4.32 per day, $131.52 per month, and $1,578.27 over the course of a year, after subtracting the cost of $0.06/kWh for electricity. 24 to 25 months are projected as the return on investment period. An S19 costs $3,225 on average in the market.

Antminer S9

Model S9 the most popular brand of “ashik Antminer outlined the key characteristics of miners for both Bitmain’s manufacturer and rivals. It started with the 9-series on a 16nm chip, and only with the introduction of a new, more contemporary chip has its number changed in the larger side.

The rectangular Antminer S9 case and subsequent devices were made of aluminum and had coolers on the front and back panels. With the right number of fans, the fans effectively cool working nodes with air.

The parallel layout of the Antminer S9, which was repeated for all other models, made chip replacement and repair simpler and permitted the installation of heat sinks between the chips to dissipate extra heat.

Antminer S9 Profitability

The Antminer S19 can generate $-1.02 per day, $-7.17 per week, and $-31.59 per month for its owner after subtracting the cost of $0.06/kWh for electricity.

The Antminer S19 and Antminer S9 are both popular models of Bitcoin miners manufactured by Bitmain.

The Antminer S19, released in May 2020, is part of the S19 series and offers a hash rate of 95 TH/s. It operates with a power consumption of 3250 W and has an efficiency of 34.2 J/TH. With its 7nm+ chips, it delivers high performance in terms of mining Bitcoin using the SHA256 algorithm. The S19 measures 195 x 290 x 400mm and weighs 14500g. It operates at a noise level of 82db.

On the other hand, the Antminer S9 was released in September 2017 and was a widely popular model at the time. It offers a hash rate of 13.5 TH/s and operates at a power consumption of 1350 W with an efficiency of 0.098 J/GH. The S9 utilizes 189 BM1387 chips manufactured on a 16nm process. It has a compact size of 135 x 158 x 350mm and weighs 4200g. The noise level of the S9 is around 71db. However, it is important to note that the Antminer S9’s profitability has significantly decreased over time due to the continuous advancement of mining technology.

In comparison, the Antminer S19 offers a significantly higher hash rate, power efficiency, and potential profitability compared to the Antminer S9. The S19 is designed with more advanced chip technology and provides better performance for mining Bitcoin. However, it is important to consider the cost of the machines and the changing dynamics of the cryptocurrency mining market when deciding which model to choose.

Evaluating a Miner

When you want to evaluate a miner, there are usually three main factors you need to check:

Power Consumption

How much electricity does the miner use? This is crucial because mining Bitcoin will result in a significant increase in your electric bill. The lower the number, which is expressed in watts, the better.


The miner has this amount of processing power to solve the mining math issue. The number of guesses the miner can make per second is essentially measured. ASICs of today can make 1*1012 guesses per second, compared to a personal computer’s few million guesses per second. It is better to have a higher hashrate.

Energy Efficiency

High hashrates are desirable, but if you expend a lot of energy to achieve them, you’ll end up losing money. Calculating efficiency basically means figuring out how much energy is needed to produce one bitcoin. Bitcoin mining with an efficient miner uses less electricity. By dividing energy consumption by hashrate, efficiency is calculated. In this manner, you can compare miners to one another effectively. Make sure you have all of the aforementioned elements before continuing because they are crucial for determining profitability. Once you know this data, you can use a Bitcoin mining calculator to estimate how many bitcoins you can produce each time period.

Remember that this calculation will never be 100% accurate because you cannot know with certainty the current difficulty measurement or what will happen to Bitcoin’s price in a week.
