Bitmain, the world’s largest bitcoin miner manufacturer, has announced the release of a new 7nm bitcoin miner – Antminer S15.

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. pic.twitter.com/m6HbWGZS1O — BITMAIN [Not giving away ETH] (@BITMAINtech) November 6, 2018

The company claims that the new 7nm miners possess industry-leading hash rates designed to mine with the SHA256 algorithm. Two models, Antminer S15 and T15, will be offered and available for purchase at 14:00 (GMT+8) this Thursday November 8, according to its official announcement.

While no detailed specs or price of the new miner have been revealed yet.

According to Jihan Wu, CEO and co-founder of Bitmain, the new ASIC SHA256 algorithm acceleration chip – BM1391 chip – uses one of the world’s most advanced semiconductor manufacturing technologies, 7nm Finfet, integrating more than a billion transistors and is optimized for maximum efficiency. Wu said tests have shown that the chip can achieve an energy/hash ratio of 42J/TH.

The arrival of 7nm chip is notable since it ushers in more hashing power for bitcoin miners. That has kicked miner makers into high gear.

Earlier this June, Japanese tech giant GMO fired the first shot in the 7nm arm race. The GMO 7nm ASIC miner named B2 is reportedly providing a hash rate of 24TH/s and power consumption of 1,950W per unit, which breaks down to 81W/THs with price at $1,999.

In August, Avalon maker Canaan also released its “world’s first” 7nm bitcoin mining chip. The ASIC, with 60-70W/THs power consumption, could deliver a hash rate of 30Tera hash per second, which became a hit in the market with its remarkable performance.

World’s third largest miner manufacturer Ebang also stepped up its effort and recently revealed its E11 series, among which the notable Ebit E11++, though still adopting 10nm chips, could reach an ideal hash rate as high as 44TH/s and power consumption ratio of 45W/T, with the price at $2,024.

Bitmain, who used to dominate the mining market with its Antminer S9 (14TH/s) in the past two years, has kind of lagged behind its rivals after their massive rollout of more powerful and efficient miners. However, if Bitmain’s figures (42J/TH) of the upcoming new miner prove to be accurate, it may see its heyday back. As reducing power consumption is an important factor for miners in seeking return on their investment, especially in the “crypto winter”. However, to seize the chance, the company must start shipping as soon as possible.
