The company Bitmain Technologies has announced the release of a new 7-nm chips “with revolutionary efficiency” for mining cryptocurrency based on the SHA256 algorithm.
According to the company, the ASIC chip of the next generation BM1397 “reaches new heights in performance, silicon area and energy efficiency for mining cryptocurrencies such as Bitcoin (BTC) and Cash (BCH)”. The chip is manufactured using a 7-nm FinFET process TSMC Taiwanese Corporation.
Bitmain claims that energy efficiency BM1397 is 28.6% higher than the previous 7-nm chip BM1391, and the energy consumption will be about 30 Joules on 1 TH of computing power (J/TH). To achieve these indicators the development team is “carefully tuned chip design to optimize the architecture, schema, and the economy.”
New ASIC chips will be used in the miners Antminer S17 and T17, which will be presented to the company later.
We will remind that in November, Bitmain announced the release of two new ASIC miners with 7-nanometer chips designed for cryptocurrency mining-based algorithm SHA256 Antminer S15 and T15. It was alleged that during the tests the devices used in mining-chip BM1391 showed an energy efficiency of 42 J/TH.
