In 2023, is it suitable to use miners to mine or buy coins? In recent years, with the increasing popularity of blockchain technology and the rapid development of digital currency, more and more people have joined the team of mining and buying of coins. In 2023, for most people, choosing to use a miner to mine or buy coins will be a critical decision. Advantages and disadvantages of miners High power consumption, high cost, and high technical requirements are the salient features of miners' mining. But at the same time, miners also have a stable income from mining and have the advantage of controlling the speed of block verification. Here are a few viable Bitcoin miners and their profitability in 2023. Antminer S19 Pro is a miner produced by Bitmain , which is very popular in the market. It is equipped with 114 BM1398 ASIC chips , which can achieve a faster and more stable mining experience. It is estimated that the average daily income of this type of miner in 2023 will exceed 120
Antminer S9K, S9SE Evaluation
In June 2016, Bitmain released the Bitcoin Antminer S9, using 189 Bitmain self-developed BM1387 bitcoin miner chips of the latest generation, with a hash rate of 11.85 TH/s, a power of 1172W, and a power consumption ratio of 100W. /T. The BM1387 chip is the fifth-generation bitcoin miner chip independently developed by Bitmain. It adopts TSMC's 16-nanometer FinFET process and is designed with a fully customized solution. As a result, the maximum hash rate of a single chip can reach 74GH/S.
Model | Hash rate (T) | Power consumption (W) | Power consumption ratio (W/T) | Number of chips | Time to market |
S9 | 11.85 | 1300 | 109.70 | 189 | 2016.3 |
S9i | 13.5 | 1320 | 97.78 | 189 | 2018.5 |
S9j | 14.5 | 1350 | 93.10 | 189 | 2018.5 |
S9 Hydro | 18 | 1728 | 96.00 | 216 | 2018.11 |
S9k | 14 | 1148 | 82.00 | 180 | 2019.7 |
S9se | 16 | 1280 | 80.00 | 180 | 2019.7 |
The Antminer S9 series has been in existence since 2016. The first Antminer S9 started with a hash rate of 11.852. Different models of S9 with different hash rates have been iterated continuously, and 13T and 14T versions have also been launched. In May 2018, Bitmain continued to launch upgraded versions of S9 with models S9i and S9j. The hash rate ranged from 13T-14.5T, and the power consumption was further reduced. In the winter of 2018, the market was also in the cold winter season. Bitmain also developed a water-cooled S9 Hydro bitcoin miner with a hash rate of 18T and power consumption of 1800W.
After many winters and summers, Antminer S9 still occupies a dominant position in the Bitcoin mining industry. Today, we evaluate the latest Antminers S9K and S9SE of Bitmain's Antminer S9 series.
Antminers S9K 14T and S9SE 16T were launched in July 2019. The Bitcoin market just experienced a small peak at that time, and the price reached $1,413.83. So perhaps this miner was born for this wave of the market.
Antminer S9SE-16T and S9K-14T are shorter and smaller than the first-generation S9. The physical size of Antminer S9K 14T and S9SE 16T is 321.3*129.6*200mm, and the weight is 4.56kg.

The number of power plugs of the three models of S9 is the same. There are three 6-pin power plugs on each of the three hash boards of the miner, plus the power supply connector of the control board; each miner needs 10 6-pin power connectors. It's just that the new generation of miner plugs has been replaced with more high-temperature-resistant materials.

The Antminer S9k 14T uses a chip codenamed BM1393B-BGM independently developed by Bitmain. The chipping process is 16nm. The three hash boards contain a total of 180 ASIC chips.

Antminer S9SE 16T also has 3 hash boards and uses 180 TSMC 16nm ASIC chips codenamed BM1393CE-BGM.
Antminer S9SE 16T is the latest generation of S9 from Bitmain. The difference from previous generations is that a protective cover is designed for the position of the control board and power interface. It can be removed by removing the middle screw at the back of the cover, convenient for installing the power cable.
Although the added cover increases the racking process, it provides protection for the control board, the power interface, and the style of the miner power supply after the installation is completed.
The measured power consumption of the Bitmain Antminer S9K-14T is 1273W, the btc.com mining pool receives stable 24-hour reception, the average hash rate is 14.21T, and the measured power consumption ratio is 89.58W/T.
The Bitmain Antminer S9SE 16T measured power consumption is 1378W, the btc.com mining pool receives stable 24-hour reception, the average hash rate is 16.03T, and the measured is 85.96W/T, which is 4% lower than the S9K power consumption ratio.
Years have passed, and the classic Antminer S9 series continues to occupy a place in the Bitcoin mining industry and is still active in the mining circle.
