Antminer S19 disassembly review after running for more than one year

High-computing BTC model, the leader of mainstream mining machines, with strong computing power, stable operation, high cost performance, chips from TSMC, technology leading the industry by one and a half generations, the new generation of computing power king S19 XP is about to subvert the debut

Geek: Luban, the Antminer S19 series has been hotly sought after by the market for more than a year since its launch. Its cumulative shipments ranked first in the high-computing power ASIC mining machine market share during the same period.

Lu Ban: Cool , there are multiple models in the S19 series, which one is the most popular?

Geek: S19 95t is the most popular product in this series. It is equipped with a 7nm process chip, with a rated computing power of 95TH/s±3% ; energy efficiency ratio of 34.5J/TH±5% ; power consumption on the wall of 3250W±5% . I wonder if its performance, computing power and energy efficiency ratio will be as good as when it was first launched after running for a period of time. Luban, you can test it yourself.

Lu Ban: OK, wait for my news.

Geek: Luban, what’s the situation now?

Luban: I have arrived at the scene and am going to randomly select a second-hand S19 95t for testing. This is it.

Geek: How many months has it been running?

Lu Ban: From the appearance, the body of the machine is covered with a layer of dust, which means it has been used for a while. I checked the SN code again, and the result showed that " the device has expired " , which means that the machine has been used for more than a year.

Geek: How’s the exterior design?

Lu Ban: Antminer S19-95T adopts an aluminum alloy profile mechatronic design and a parallel four-fan structure. Its overall design follows the previous two generations of mining machines, and adopts a double-tube design to enable the hashboard to dissipate heat better. There are two fans at the front and back of the mining machine, one for the air inlet and one for the air outlet, which have better temperature adaptability. The entire mining machine is highly integrated, and the power supply and control board are all integrated designs, making operation and maintenance, as well as loading and unloading more convenient.

Geek: See it in action.

. . . ( 46 hours later). . .

Lu Ban: To ensure the data is authentic, I tested it for almost two days and two nights. Look at my panda eyes.

Geek: Stop kidding, give me the data.

Luban: According to the backend data, the average hashrate in the past 46 hours was 95.8TH/s (interpretation: 95.8TH/s=95813Gh/s multiplied by 1000 ) , the power consumption was between 3150w and 3180w , and the actual energy consumption ratio was about 32.8J/TH . At the same time, I saw that the fan speed was normal, the temperature of the mining machine's air inlet was 38℃ , and the temperature of the air outlet was 58℃ . I will test the noise again.

The noise level was measured to be between 80 dB and 95 dB . As our test environment was relatively noisy, excluding the influence of environmental noise, the sound of the mining machine itself was also within the normal range.

Geek: After more than a year of actual operation, the actual computing power of the machine is still consistent with the official release, and the power consumption and energy consumption ratio are even lower than the official release, which is very good!

Lu Ban: That’s right! This machine has strong computing power, high cost performance, and stable operation, which is achieved by enhancing the circuit architecture. Therefore, after one and a half years on the market, it is still popular, with good user reputation and market response.

Geek: Very good. Luban, there is another piece of news. Bitmain announced its next-generation ASIC model S19XP at the World Digital Mining Summit held in Dubai . According to official data, the rated computing power of S19XP is 140TH/s ; energy efficiency ratio is 21.5J/TH±5% ; wall power consumption is 3010W±5% .

Lu Ban: That’s so cool. That is to say, compared with the current S19 series, the S19XP has made significant improvements in both computing power and energy efficiency!

Geek: Yes. Through the release of S19XP , we can see that the overall technology of Antminer is at least 1-2 years ahead of the industry. No wonder it has become the industry's top TSMC chip partner.

Lu Ban: I am very much looking forward to whether S19XP will once again subvert the market's perception of Bitcoin ASIC mining machines, and whether it will open a new era of Bitcoin computing power as a pioneer!
