Bitmain Announces New 7nm Antminers for Bitcoin Mining

The largest Bitcoin mining manufacturer, Bitmain Technologies Ltd, on Nov, 5 announced on Twitter that its 7nm ASIC (Application-Specific Integrated Circuit) has been designed and is set for release. Bitmain as the company is popularly known has been designing devices for mining cryptocurrencies since 2013.
The ASICs which are to be released, are pieces of hardware devices that have been customized for a specific use. In this case, for the mining of Bitcoins based on hashing rates that have already been specified. Therefore, the two variants that are expected are the Antminer S15 and T15, and they will take advantage of the SHA256 algorithm.
According to the Beijing-based Company;

We are officially announcing the release of our new 7nm miners which possess industry-leading hash rates designed to mine with the SHA256 algorithm. Two models will be offered, the Antminer S15 and T15. Available for purchase on 11/8.

While some crypto miners are excited about this development and are inquisitive about the specifications of the Antminers S15 and T15, Bitmain has withheld this information until the devices are launched on Thursday at 14:00 (GMT+8). Nevertheless, users can still rely on the bits of information which were provided by this manufacturer at the World Digital Mining Summit in Georgia, on September, 21.
To get an idea of what these chips can do, they have been optimized to provide a high level of performance with the use of a 7nm (nanometer) Finfet semiconductor technology and over a billion transistors. During a lecture in the Summit, the CEO of the company, Jihan Wu stated that;

Tests have shown that the chip can achieve a ratio of energy consumption to the mining capacity that is as low as 42J/T.

He had also referred to the fact that the increasing traffic on Blockchain was as a result of the maturity of the crypto industry and as such, it will demand a chip with more data processing power than what was obtainable before. This will be a chip with hardware acceleration and parallel computing technologies.
Miners are hoping that these chips will compete with the Canaan’s AvalonMiner A911. The latter is Bitmain’s closest rival and the second largest manufacturer of hardware for mining cryptocurrencies. Its AvalonMiner A911, has a power consumption of 1440w, a maximum hash rate of 18 TH/s (Tera hashes per second), and power usage of 80 watts per THS.
Finally, there’s another ASIC chip known as Bitfury Clarke which was released this year on September, 19 by the Blockchain technology company, Bitfury group. This chip features a 14nm semiconductor device, SHA256 bitcoin mining algorithm, 55 millijoules per gigahash (mJ/GH) power efficiency rate, and hash rate up to 120 gigahashes per second (GH/s).
