8btc lab review on Antminer B3, the Bytom ASIC

8btc lab has conducted a test on the Antminer B3, the Bytom ASIC. Video report could be found below.

The word blockchain has become one of the hottest words in 2018. More and more relevant articles appeared in daily news. Many Bytom supporters could not wait to know more and participate in mining. Bitcoin mining has undergone a process from CPU -> GPU -> FPGA -> ASICand currently focuses on ASIC mining. Like Bitcoin, Bytom also uses PoW algorithm, which is friendly to ASIC mining rigs. The total supply amount of Bytom token is 2.1 billion and the amount for mining is 693 million. After the Bytom Mainnet released, Antminer B3 became a favored target for miners.

Many Bytom supporters want to mine BTM, but suffer from lacking of knowledge of mining. So today I will take everyone to see Antminer B3. The miner you bought on Bitmain’s official website is bare machine. Users also need to purchase power supply units, prepare power cables and network cables. For the PSU, you can purchase online or use your old one as long as the power is plenty enough and there are seven or more power cords available. The quality of PSU is crucial to the stability of your miners. Insufficient power may cause problems in the operation of your mining rigs or even burn the chips.

The Antminer B3 chassis is made of aluminum alloy material, equipped with three computing boards and a controller board. The chassis uses front and rear dual cooling fans design to provide efficient heat dissipation for the miner. If we tear down a B3, we will find that each computing board contains 4 Sophon BM1680 chips, in totaled 12 chips for every miner.

Now let’s take a look at the installation process of B3. Firstly, connet miner to the network. Then insert these six-pin power cords to computing boards and the controller board. The controller board has one interface, and each computing board has two interfaces. Then turn on the PSU and the miner goes alive.

At present, Antpool, F2pool, BTCC, Spider pool, UUPOOL, Poolin, 91POOL and Viabtc mining pool have announced to support Bytom mining. Let’s take a look at how to connect our miner to a mining pool. First, create an account in the pool‘s website and initialize your account. Then on the settings section, input your wallet address. Take Antpool as example, you must fill your own Bytom wallet address correctly, and then the pool configuration is completed.

After the mining pool is configured, you need to configure the miner. Now you need to find the miner IP and then log into the background interface. If there is not much device in your local network, you can find the IP address of the miner easily. In addition, it is also possible to use the LAN IP finder provided by the miner manufacturer to obtain the miner’s ip. After that, input ip to the browser and log in to the mienr’s background. The default username and password both are root. Filling out the specified url provided by the mining pool and the account name created previously, the configuration of the miner is completed.

you can start mining now. turned on the power, initially, the miner is only warming up so the noise is low. After another 1 minute, the miner started mining and the noise goes much louder. Since the miner was put together with the PSU, the noise level we measured in the room is from both PSU and miner. We tested the miner’s noise with a Bitmain APW3 PSU and a Great Wall Dragon PSU seperately. When using APW3 PSU, the noise is 85 dB when our tester is 10cm away from the air inlet; the noise is 88 dB when our tester is 10 cm away from the air outlet; 72.8 dB when 1 m away. When using the Great Wall PSU, the noise is 84 dB, 10 cm away from the air inlet; and 86 dB, from the air outlet; The noise is 72.8 dB when 1m away from the miner. This shows that the choice of power supply has a certain impact on the noise level; if you care about the noise, you’d better choose a power supply with low noise.

Taking the noise in life as an example, a car passing by 10 meters away is about 70 dB, and the noise of the miner exceeds that. Therefore, it is not a good idea to put your miner in your living room. If you want to make it quieter, you can use a soundproof box or a fan deceleration cord. However, these methods may slow down the dissipation of heat produced by miners.

The rated power consumption of B3 is 360W, and the measured power consumption is about 374W, slightly higher than the nominal one. It’s easy to calculate that B3 consumes about 9 degrees of power per day. If the electricity charge is 0.5 RMB/degree, the estimated electricity cost for mining one day is 4.5 RMB. Due to continuous growth in the computing power of the whole network, the revenue cannot be estimated accurately. But, you can calculate yourself with to the following steps: Under ideal conditions, the average time for a new Bytom block is about 2.5 minutes and the reward for a block is 412.5 BTMs. Assuming 5,000 mining machines in total in the network and not considering gpu miners, the number of BTMs that can be mined everyday are 24×60/2.5×412.5/5000=47.52.

After two days of continuous mining, we can check from the background that the average computing power is about 903 H/s, and the instantaneous computing power fluctuates from 800 to 1000 H/s, which is slightly higher than the nominal one. The current room temperature is about 23 Celsius degree, and the temperature of the mining chip is about 40 degrees on average.

The difference between the antminer B3 and the other ASIC miners is that it can be used for artificial intelligence computing acceleration. Antminer B3 supports the Tensority algorithm, which can perform deep-learning matrix operations for artificial intelligence cloud acceleration services, reducing hardware waste and making computing more socially valuable.
