In this article, the Antminer S19j and Bitmain Antminer S19 will be compared in terms of their features, hashrate, energy efficiency, and profitability.

Through its brand ANTMINER, which has long maintained a global market share and a leading position in technology, BITMAIN is the world’s top manufacturer of cryptocurrency mining servers, serving clients in more than 100 countries and regions. Singapore, Malaysia, Kazakhstan, the United States, China, and other countries all have branches of the company.

The basic Bitmain model has been upgraded to the Antminer S19j. However, the S19j is somewhat inferior to the S19 running stock firmware.

Let’s take a detailed look at these two miners.

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 mining cryptocurrencies like Dash, Litecoin, and Bitcoin.

You’ll know you’re making the right choice when you see “Bitmain” mentioned in connection with a device or chip you’re thinking about purchasing. Bitmain has established itself as the market leader for mining rig chips. It is believed to control 80% of the crypto mining market, which is a sizable portion. Have you ever heard of Antpool or BTC.com? Moreover, Bitmain owns and manages two of the biggest Bitcoin mining pools.

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 you can find 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.

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 significant electricity costs. The better the value—which is expressed in watts—the less energy is being used.

Hashrate

To solve the mining math problem, the miner needs this amount of processing power. 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 the few million guesses per second that a personal computer can make. The more hashrate you have, the better.

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 involves figuring out how much energy is needed to produce one bitcoin. Bitcoin mining with an effective miner uses less electricity. Energy consumption and hashrate are divided to determine efficiency. In this manner, you can compare miners to one another effectively. Make sure you have all of the aforementioned elements before moving forward because they are crucial for determining profitability. Once you have this knowledge, you can enter it into a Bitcoin mining calculator to determine 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.

Conclusion: S19j’s Power Efficiency is Slightly Lower Than the S19’s

One of Bitmain’s ashik models, the Antminer S19j, is the most contentious. On the one hand, the manufacturer has positioned it as an improvement over the entry-level model, taking into account technological advancements, and even the number of chips in the ashik increased – from 76 in S19 to 114 in S19j. However, in practice the performance of both ashiks is identical, and on the stock firmware S19j is even somewhat inferior to the “older fellow”.
Antminer S19j demonstrates the following characteristics:

· Algorithm supported: SHA-256

· Hash rate: 90 TH/s

· Power consumption: 3100W

· Dimensions: 400mm/195.5mm/290mm

· Weight: 14.2 kg

· Noise level: 75 DB

Antminer S19 demonstrates the following characteristics:

· Supported Algorithm: SHA-256

· Hash rate: 95 TH/s

· Power Consumption: 3250W

· Dimensions: 400mm/195.5mm/290mm

· Weight: 14.4 kg

· Noise level: 82 DB
However, the power efficiency of the S19j is marginally inferior to that of the S19 on stock firmware (34.5 W/TH vs. 34.2. In other words, the real performance of the new ashik is identical to the base model even though the S19j is more than a year newer and has more chips.
