Chinese mining giant Bitmain’s 7nm Bitcoin miners go on sale today, November 8, 2018.
Announced in September of 2018, the miners allegedly offer considerably faster hash rates (though Bitmain didn’t disclose any specifications) and come in two separate Antminer models: the S15 and T15.
The company first provided the news on Twitter, writing, “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.”
Bitmain’s new ASIC chips will operate via 7nm Finfet, which Bitmain refers to as “one of the world’s most advanced semiconductor manufacturing technologies.” The chips utilize more than a billion transistors each.
In addition, 7nm technology enables the chips to consume less power and mine at much faster paces. In a keynote lecture two months ago, Bitmain CEO and co-founder Jihan Wu said that the chips would “achieve a ratio of energy consumption to the mining capacity that is as low as 42J/T.”
Mining companies everywhere are now seeking to compete with Bitmain and strengthen their spots in the industry. Just 24 hours before Bitmain made its September announcement, the Bitfury Group unveiled its own 14nm ASIC chip called the Bitfury Clarke, which is also customized for SHA256 Bitcoin mining and built to compete with Bitmain’s upcoming model. Bitfury stated that the chip could execute a hash rate of up to 120 gigahashes per second, and a power efficiency rate of roughly 55 millijoules per gigahash.
Another competitor working to up the ante is U.S.-based semiconductor manufacturer AMD. In October, the venture reported that crypto-mining sales were “negligible” in quarter three of 2018,
