As a miner with multiple algorithms, Baikal Giant-A900 can support six kinds of algorithms (X11, X13, X14, X15, Quark, Qubit) with the main features of high hashrate and low power consumption.

Official parameters of Baikal Giant-A900 miner (hereinafter referred to as A900):

AlgorithmHashratePower Consumption
X11900 MH/s ± 10%217w ± 5%
X13900 MH/s ± 10%255w ± 5%
X14900 MH/s ± 10%263w ± 5%
X15900 MH/s ± 10%270w ± 5%
Quark900 MH/s ± 10%132w ± 5%
Qubit900 MH/s ± 10%146w ± 5%

Based on the data, we can see that the ratio of hashrate and power consumption of ASIC miners has been increased by dozens of times compared with GPU miners. (The table of known data is shown as follows with slight deviations based on different brands of video card).

Summary

  • With extremely good performance, Baikal Giant-A900 supports up to six algorithms, which is the high-hashrate miner capable of the most algorithms so far with perfect ratio of hashrate and power consumption. Compared with the GPU miners supporting 6 algorithms nowadays, the ratio of hashrate and power consumption has been increased by dozens of times, which greatly reduces the mining cost.
  • After long term of operation, the hashrate curve is stable with good overall performance. In stable mining pool and network conditions, the average hashrate is between 910M and 930M.
  • Due to good heat dissipation, the temperature difference between the inlet and outlet is very small, and the wave design of cooling fin increases the unit heat dissipation area.
  • A little noisy and the noise sounds a little dull (not sharp). The mining workers with DIY capability can replace it with a low-noise and high-volume cooling fan. However, there may be little effect on performance.
  • The interface on configuration page is intuitive and convenient with multiple functions.
  • The automatic algorithm switching function realizes the maximum profit of the customer in the multipool, so that they will not worry about the algorithm selection any longer.
