Introduction

The high-performance computing chip developed by Jinbei gives CK5 12t powerful computing power. At present, CK5 performs very well in a number of CKB mining machines.
Want to know what the real performance of Jinbei CK5 is? Jinbei CK5 miner is a CKB special ASIC miner developed based on eaglesong algorithm. This model claims to have 12t computing power and its declared power consumption ratio is as low as 0.2w/g

The factory packaging of Jinbei CK5 mining machine is carton, and no product model and other information are marked outside the carton. Open the packing box, which contains CK5 miner fully embedded and protected by Pearl foam and a supporting power cord. For the measured packages with original boxes of foam, there is no need to worry about the damage to the machine caused by bumps and violent sorting in transportation.

The measured three-dimensional length of CK5 miner received is 280mm (including fan thickness) * width 180mm * height 290mm,. The weight of bare machine is 0.9 kg, including 10.9 kg of raw wire.

The miner and power supply are designed as a whole. CK5 miner is equipped with Shanghai Yigong model bp-h-2800-10-a power supply with peak power up to 2800W. The power cord equipped with this power supply is also the plug of 16A large socket, which is different and non universal from the power cord of 10A socket of household miner in the past. Therefore, it also shows that this type of miner is not suitable for mining at home. If it is used at home, the circuit needs to be modified to meet the power load of the miner.

There are four fans in total, two air inlets and two air outlets. The fan model is snowfan yy1203, DC12V, which is a common fan in the mine. Because the engineering prototype obtained by Xiaobian has undergone stability test, some dust has accumulated on the fan, which can be ignored.
The four fans can meet the heat dissipation during normal operation, but the operation noise is relatively large. It is nearly 90dB when plugged in and started for the first time. Even after one day of stable operation, the operation sound measured at the air outlet is 80dB, and the operation noise outside one meter is 72.9 dB.

Before calculating the mining revenue, we should first understand several concepts: Difficulty, Hashrate, Block Reward, and 24h Estimated mining revenue. Take BTC for example:

Calculation of BTC mining income

Bitcoin shows how difficult it is to mine through multiple transforms, it can be simply understood as: assuming the corresponding mining difficulty is “1”, it takes about 232 times hash operating, in order to get a random number needed for a legal new block in theory, that is mining a legal new block theoretically.

So, it can be inferred that, when the mining difficulty is D, (D×232) times hash operating are needed to dig a legal new block, and R units BTC can be obtained as a block reward. If the miner's computing ability is H, then the time it takes him to complete (D×232)times hash operating equals (D×232) /H seconds.

Theoretically, the miner's mining revenue per second equals R÷ (D×232) /H BTC. 24 hours a day, a total of 24×60×60 seconds, the estimated daily mining revenue of BTC as below:

P=Hx 1/(Dx 2^32)R x (24x60x60)

For example:

Current BTC difficulty D=12720005267390.51

Reward per BTC block R= 12.5BTC

1Ph/s hashrate

Daily mining revenue= 1x10^15 x(1/12720005267390.51x 2^32)x12.5x24x60x60,

Available: P= 0.01976863 BTC

BTC and ETH are two typical crypto currencies. The mining revenue calculation of other currencies are similar to these of BTC and ETH.
