This article will reveal the top six cryptocurrencies to consider buying in 2023. MATIC Polygon, formerly known as Matic Network, is a blockchain platform that facilitates the development and scaling of Ethereum infrastructure. It transforms Ethereum into a multi-chain system and provides a common framework for developing various types of applications. Besides that, Polygon SDK can be used to create optimistic rollup chains, ZK rollup chains, and standalone chains. The platform can process up to 65,000 transactions per second on a single sid
Baikal Giant A900 X11 Miner Review
Baikal Giant A900 is a miner that can support six algorithms, including X11, X13, X14, X15, Quark, Qubit, and its main features are high hash rate and low power consumption.
The official parameters of the Baikal Giant-A900 miner:
Algorithm | Hash rate | Power Consumption |
X11 | 900 MH/s ± 10% | 217w ± 5% |
X13 | 900 MH/s ± 10% | 255w ± 5% |
X14 | 900 MH/s ± 10% | 263w ± 5% |
X15 | 900 MH/s ± 10% | 270w ± 5% |
Quark | 900 MH/s ± 10% | 132w ± 5% |
Qubit | 900 MH/s ± 10% | 146w ± 5% |
According to the data, we can see that the hash rate and power consumption ratio of ASIC miners are dozens of times higher than that of GPU miners.
Miners unpacking photos
The A900 miners are packed in industrial cartons, and the miners are wrapped with shock-proof and anti-collision bubble wrapping pads.
The miner's manufacturer logo is located at the bottom left of the miner.
The miner's control board is located on the miner's top and is powered by the hash board.
A data cable connects the two hash boards of the miner and is then connected to the control board.
The lateral side of the miner.
The front of the miner consists of a network interface and a single 12cm cooling fan.
On the back of the miner, we can see that the miner is composed of two hash boards, of which the top and bottom of the miner are composed of a PCI-E 8pin power interface and a fan protection net.
The miner's heat sink uses alloy fins with wavy lines.
The whole miner parameter diagram is as follows:
Performance testing
The miner test power supply uses a SUPER FLOWER 500W power supply, and the conversion rate is close to 80PLUS GOLD. In this test, the indoor noise is about 39dBa, and the indoor temperature is about 25℃.
The X11 mining hash rate curve is stable, and the overall performance is good, with an average hash rate between 910M and 930M.
When the average hash rate is around 910M, the test power is 215w.
In terms of noise, the measured noise is about 65dBa at a distance of about 20cm from the miner.
The noise measured about 1m from the miner is about 58.6dBa.
In terms of temperature, the temperature of the test chip on the mining status page is 33°C, and the test temperature of the air inlet is about 25.3°C.
The test temperature of the air outlet is about 28.6 ℃.
The test temperature of the heat sink is 28.8°C.
Generalize
· Baikal Giant-A900 has excellent performance and supports up to 6 algorithms, making it the miner with the most algorithms so far. Compared with the GPU miners that currently support six algorithms, the hash rate and power consumption ratio are increased by dozens of times, significantly reducing the mining cost.
· After a long-term operation, the hash rate curve is stable, and the overall performance is good. Under stable mining pool and network conditions, the average hash rate is between 910M and 930M.
· Due to good heat dissipation, the temperature difference between inlet and outlet is slight, and the wave design of the heat sink increases the unit heat dissipation area.
· Miner noise sounds a bit dull. Capable miners can use low-noise and high-volume cooling fans instead.
Appendix
Actual power consumption of A900 miner and other algorithms:
· When the hash rate of the Qubit algorithm is 900M, the estimated power is 140w.
· When the hash rate of the Quark algorithm is 900M, the estimated power is 125w.
· When the hash rate of the X15 algorithm is 900M, the calculated power is 262w.
· When the hash rate of the X13 algorithm is 900M, the estimated power is 256w.
