Canaan Technology Launches New Avalon A13 Series Bitcoin Miners

Canaan Technology Launches New Avalon A13 Series Bitcoin Miners According to the latest news, Canaan Technology announced the launch of the new Bitcoin miner Avalon Made A13 series, including Avalon A1346 and Avalon A1366. Canaan Technology said that the new generation of miners uses advanced ASIC technology, and the A13 series will include two different models. Compared with the 90 to 100TH/s hash rate offered by the A12 series, the A13 series has both hash rate, and energy efficiency has been enhanced. Canaan's CEO said the all-new A13 is a milestone in the company's over-computational energy consumption analysis. The model A1346 has a hash rate of 110 TH/s and an energy efficiency of 30J/TH. Model A1366 has a hash rate of 130TH/s and an energy efficiency of 25J/TH. Comparing the energy efficiency ratio of Bitmain's flagship S19 XP of 21.5 J/TH with that of Bitmain's M50S of 0.026j/Gh, the new series of A1346 is "very competitive" in terms of efficiency at

Dash Antminer D3 19.3 Gh ASIC Miner Review

Dash Antminer D3 19.3 Gh ASIC Miner Review

Dash was born in 2014. Compared with Bitcoin, it has the characteristics of higher anonymity and faster transaction speed. In August 2017, Bitmain officially launched Dash Antminer D3, a new ASIC miner launched by Bitmain for a single encrypted digital currency after the Bitcoin and Litecoin miner series. Here ZEUS MINING has conducted a comprehensive evaluation of it, and then let's take a look at the performance of D3!

Appearance and workmanship

The outer packaging of Antminer D3 is packed in an industrial carton. When you open the outer box, you can see that the miners are protected by shock-proof and anti-collision bubble wrapping pads, which ensures that the miners will not be damaged during transportation.
miner package
Antminer D3 adopts a dual-fan, three-hash board miner design; the body is integrally formed, a precision die-casting design, and aluminum alloy material, which provides robust protection for the hash board chip and improves the overall heat dissipation efficiency of the fuselage.

Looking down from the top of the miner, you can see that D3 has three hash boards, each of which has three PCI-E6pin interfaces, and you can also see three data lines from the hash board to the control board.
connection between hash board and control board
From the front of the miner, you can see the IP address feedback button, network cable interface, reset button and status indicator, and other configurations (as well as the Antminer D3logo and QC label). In addition, the fan with a diameter of 12cm can be seen on the front, and the air is fed from this side.
From the miner's back, the miner's cooling fan can be seen, and the air is released from this side.
D3 uses Bitmain's self-developed chips, and each hash board has 60 BM1760 chips. The overall structure of the miner is very compact. However, the interval extension between the hash plates brings a larger heat dissipation area. The interval also forms a unique air duct inside the miner, which can maximize the use of the fan and the structural cavity to push the heat dissipation effect to the extreme.

Installation and debugging

The power supply for this test uses Antminer APW3+, and the mining pool uses Antminer Pool under Bitmain. For the connection of D3 miners, please refer to the AntMiner D3 Manual.

Heat and noise

Antminer D3 adopts PPLNS mining mode. The test site is a conference room with an area of about 30 square meters. The room temperature is 28 degrees. Heat and noise tests are performed after the miner runs for 24 hours.
At a distance of 10cm from the air outlet of Antminer D3, the measured noise of miners was 88dB, but the noise dropped to 70dB at a distance of 1 meter. After closing the door, there was no more obvious sound.

After running for 24 hours, the temperature of the D3 hash board is 64 degrees, and the chip temperature is 84 degrees in the miners backstage, which are all within the normal range.

The official hash rate of the Antminer D3-19.3G version is 19.3G. The actual test's average hash rate is around 19.41GH/s, which is higher than the nominal value. The power of the Antminer D3-19.3G version in the actual test is 1278W, and the power consumption per G hash rate is 65.8W/G.
As of January 2022, according to the PPLNS revenue model of AntPool, the revenue of a D3 24 hours a day is $0.70, the daily electricity cost of D3 is -$3.89 and the daily revenue is about -$3.19.

Overclocking test

The default operating frequency of Antminer D3 is 537M, the miner's frequency is set to 650M, and the overclocking operation is performed. After running for a while, the D3 hash rate increases to about 22.7G. At this time, the hash board and chip temperature are higher than that of the default state high; the hash board temperature is 74 degrees, the chip temperature is 97 degrees, and the power rise is 1589W. Under overclocking, the power consumption per unit hash rate is 70W/G, slightly higher than the default operating frequency. Therefore, long-term overclocking is not recommended.

Summarize

The overall performance of the Antminer D3 is surprising. The power consumption per unit hash rate is as low as 65.8W/G, and the hash rate remains stable under long-term work. D3 also shows good strength in overclocking.
Antminer D3 continues Bitmain's quality of fine craft, the product runs stably, and the installation is very convenient. The actual runtime hash rate will be slightly higher than the standard. D3 is not very noisy. After closing the door, there is no noise. It can also be used in civilian rooms.
