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

What is the Antminer BM1489 ASIC chip?

Antminer BM1489 ASIC chip is an ASIC chip on the Bitmain Antminer L7 hash board for mining Litecoin and Dogecoin.
In the integrated circuit industry, an ASIC is considered an integrated circuit designed for a specific purpose. The characteristic of ASIC is to design and manufacture special integrated circuits according to user requirements. The chips used for mining are called ASIC miner chips. Compared with general-purpose integrated circuits, ASICs have the advantages of smaller size, lower power consumption, improved reliability, improved performance, enhanced confidentiality, and reduced mass production costs. In terms of mining hash rate, ASICs are tens of thousands of times or higher than contemporary CPUs and GPUs, so ASIC chips on the market are also more popular than them.

For example, Bitmain Antminer L7, which is currently sought after by the market, is a standard ASIC miner, and it is the best choice for mining LTC in the current market. The entire miner is equipped with 288 BM1489 ASIC chips specially designed for the Scrypt algorithm. Since the hash rate has always been the most popular quality for miners, and the L7 hash rate reached 9.5 Gh/s, compared to other LTC miners, the L7's hash rate has increased significantly, several times that of its miner model. Therefore, arguably the L7 is a more robust and efficient miner than any other device that mines LTC. At the same time, LTC has no plans to switch the network to the PoS concept in the current market, so you don't need to worry about your miners being out of date due to mining LTC and withdrawing from the market.

The same with the Antminer L3+ is that the Antminer L7 has the same number of hash boards and chips, four independent hash boards, and each hash board have 72 BM1489 ASIC chips. However, compared with the general series of Antminers, which have 3 hash boards and 189 chips, the design of Antminer L7 is more unique. The body of Antminer L7 is integrally formed, using precision die-casting design and aluminum alloy materials; in addition to providing robust protection for the hash board chip, it also improves the overall heat dissipation performance of the fuselage.

Due to the high heat dissipation of the BM1489 chip, many heat sinks are usually installed on the chip of the hash board, the purpose of which is to speed up the heat dissipation of the hash board and ensure the normal operation of the miners. In addition, the L7 adopts the heat dissipation design of the front and rear dual cooling fans, which can achieve a better cooling effect for the whole miner.
The hash rate of Antminer L7 reaches 9.5 Gh/s, which is equivalent to the sum of the hash rate of 20 Antminer L3+, which aims to be the most potent miner for mining LTC and DOGE. If calculated at the current market electricity cost and currency price of $0.01 per kWh, Antminer L7 can generate a daily profit of $39.7.
The power supply mode of the hash board still adopts the power supply method in series. The layout of the PCB LAYOUT of the hash board is reasonable, and the power supply is placed on both sides of the chip, which makes better use of the space. Note that the four hash boards can be connected to different power supplies, but each cannot be connected to multiple power supplies.
After a long-term high-speed operation of the miner, the chip is a highly vulnerable component, and its faults are generally manifested in two categories: electrical parameter damage and physical damage. The electrical parameter damage also includes damage caused by voltage and current exceeding the rated value. Physical damage includes chip breakage, deformation, etc. At this time, we need to maintain the regular operation of Antminer L7 by replacing the faulty BM1489 chip.
