Understanding the new 7nm Antminer T15 in one article

Equipped with Bitmain's first 7nm chip, the Antminer T15 was launched on November 8, continuing the Antminer's miracle with its sustainability and super energy-saving level . Bringing together Bitmain's all-round technological evolution, T15 supports the SHA256 mining algorithm, allowing miners to enjoy a new mining experience with high performance and low power consumption.

In order to help all miners better understand the advantages of T15, in today's article "Understanding the Mining Machine Series", Ant Girl will lead you to fully interpret the Antminer T15!

First, let’s take a look at the specific parameters of T15. T15 has two built-in mining modes. The standard mode has a computing power of 23TH/S±2% and a power consumption of 1541W±7%; the low power mode has a computing power of 20TH/S±2% and a power consumption of 1200W±7%.

Highlight 1: Equipped with Bitmain’s first 7nm chip, high performance and more power-saving

The T15 is equipped with Bitmain's first 7nm chip, the BM1391, which integrates 1 billion transistors in a single chip. Thanks to the unique circuit structure and algorithm optimization, the computing performance of the BM1391 chip has been significantly improved, helping to comprehensively improve the mining performance of the T15.

In addition to performance improvements, BM1391 also has a major breakthrough in chip packaging. BM1391 adopts the industry-leading Exposed Die packaging solution, abandoning the traditional Overmolding plastic packaging method. In the Exposed Die packaging solution, the back of the wafer is directly in contact with the heat dissipation interface and heat sink, greatly improving the heat transfer efficiency.

The chip optimization brings excellent low power consumption performance to T15. The energy efficiency ratio of the whole machine in standard mode is 67J/T, and that in low power mode is 60J/T ! Electricity is the main expense of mining. The low power consumption of T15 will help miners save a lot of electricity, reduce mining expenses, and enable sustainable mining.

Highlight 2: Fan parallel design improves heat dissipation efficiency

Unlike traditional air-cooled mining machines, the T15 uses a new heat dissipation structure and a fan parallel design . In the new heat dissipation structure, the front of the mining machine is cooled by dual fans, and the rear uses a honeycomb heat dissipation network. The fan parallel design can shorten the heat dissipation air path and reduce wind resistance, helping to improve the heat dissipation efficiency of the T15.

On the one hand, the upgrade of the T15 cooling system can improve the long-term reliability of the mining machine and reduce the operation and maintenance costs of the mine; on the other hand, it can help reduce the operating temperature of the mine, improve the mining environment and reduce cooling expenses.

Highlight 3: Two mining modes to meet the personalized needs of miners

Antminer T15 has two built-in mining modes. The normal mode has a rated computing power of 23TH/S and an energy efficiency ratio of 67J/T, which can provide miners with greater computing power support and is suitable for miners who pursue high computing power; the low power mode has a computing power of 20TH/S and an energy efficiency ratio as low as 60J/T, with a higher energy-saving level, which is more suitable for miners who need energy saving.

The switching method between the two modes is very simple. Miners only need to select the mode they want in the background of the mining machine to switch easily!

Highlight 4: All-in-one design makes mine management more convenient

To improve the space utilization rate of the mining farm, the Antminer T15 adopts a mining machine + power supply integrated design, with the power supply hanging on the side of the mining machine. Miners can freely choose the placement of the mining machine according to the mining farm design, either vertically or horizontally, and can flexibly adapt to different mining farms and racks. The integrated design also makes it easier for miners to put the machine on and off the rack, making mining farm operations more convenient.

It is worth mentioning that the T15 is equipped with the Antminer’s new high-conversion efficiency power supply APW8. The new power supply can reduce power loss during the power conversion process, thereby helping the mine save electricity costs.
