Bitmain's 7nm mining machine S15 is released globally with significantly improved performance and energy saving as the main feature

On November 8, Bitmain, one of the world's top ten and China's second largest fabless chip design companies, and the world's largest cryptocurrency mining company, officially released the S15 mining machine equipped with its own 7nm chip, with a computing power of up to 28TH/S and an energy efficiency ratio of 57J/T. Compared with the previous generation of products, the overall performance is more stable. Antminer S15 has now officially landed on the official website and will be available worldwide today. The new S15 supports the SHA256 algorithm and can mine encrypted digital currencies such as Bitcoin (BTC) and Bitcoin Cash (BCH).

Equipped with self-developed 7nm chip, the overall performance of the mining machine is more outstanding

The biggest highlight of the Antminer S15 is that it is equipped with the world's leading 7nm chip BM1391, which integrates 1 billion transistors. The single-chip performance has been significantly improved, and the energy efficiency ratio is only 42J/T, providing a strong guarantee for the continuous and stable operation of the mining machine.

Based on the 7nm process, the overall performance of the S15 has been significantly improved, the reliability of the mining machine has been enhanced, and miners can mine continuously. Industry insiders believe that Bitmain's launch of a new generation of 7nm mining machines is of great significance to promoting the iteration of mining machine products and the development of the entire market.

Innovative Exposed Die packaging technology greatly improves heat dissipation efficiency

According to the official website, the Antminer S15 is equipped with the 7nm chip BM1391 independently developed by Bitmain. It abandons the traditional overmolding plastic packaging method and adopts the industry-leading exposed die packaging technology. The chip's heat transfer efficiency is greatly improved, which can help miners save more electricity bills.

Considering the personalized needs of global users, S15 provides two mining modes: standard and low power consumption. In standard mode, the mining machine has a computing power of 28TH/S and an energy efficiency ratio of 57J/T, which is suitable for miners who pursue performance; when low power consumption mode is selected, the computing power of S15 mining machine is 17TH/S and the energy efficiency ratio is only 50J/T, which is suitable for miners with strong energy-saving requirements.

In addition, S15 has upgraded its heat dissipation structure and adopted a fan parallel design. This solution can not only shorten the cooling wind distance of the mining machine, but also effectively reduce wind resistance, further improve the cooling efficiency of the mining machine, and enhance the stability of equipment operation. S15 uses a power supply + mining machine all-in-one design, with a new high-conversion efficiency power supply APW8, to reduce power loss during power conversion, making it more energy-efficient.

Launched a global user loyalty program dedicated to providing a wonderful mining experience

The global launch of the new 7nm mining machine will be a major milestone for Bitmain. In order to provide miners with a better mining experience, Bitmain has launched the Antminer Global User Loyalty Program to give back to old S1 users. According to the official website, old S1 mining machine users have the opportunity to receive a 50% discount coupon for the new product and exchange it for the new 7nm mining machine S15. The detailed event information plan will be announced in the near future.

In addition to the release of Antminer S15, Bitmain also simultaneously launched another 7nm mining machine T15, with a standard computing power of 23TH/S and an energy efficiency ratio of 67J/T. Antminer S15 and T15 have both been launched on Bitmain's official website and will be officially launched at 14:00 on November 8, Beijing time.

Public data shows that Antminer is the world's largest mining machine manufacturer, with a market share of over 70%. In addition to the SHA256 algorithm mining machine released this time, Antminer also has mining machine products including Scrypt, X11, Cryptonight and other mainstream encryption algorithms, fully meeting the mining needs of global users.
