Bitmain has just announced its next generation 7nm ASIC chip called BM1397 that is apparently capable of great performance and energy efficiency for mining cryptocurrencies such as Bitcoin (BTC) and Bitcoin Cash (BCH), that use the SHA256 algorithm for their Proof of Work (PoW). The new BM1397 ASIC chip requires lower power and can offer an energy consumption to computing ratio as low as 30J/TH or with other words almost 30 percent improvement in power efficiency compared to their previous 7nm chip BM1391 that is already found in the company’s latest SHA256 ASIC miners.

The new BM1397 ASIC chip is made using TSMC’s 7nm FinFET manufacturing process and it is expected to be featured in the upcoming Antminer models named the S17 and T17 that will be announced by Bitmain at a later date. There are no detailed specifications available for the moment, however ~30% better power efficiency could mean up to about 30% higher performance for the same power as the currently available AntMiner S15 and S17 ASICs that sue the first generation of 7nm chips form Bitmain. It is not all about performance however…

Really interesting news for everyone that owns Antminer S9 ASIC miners and other Bitmain BM1387-based models like the Antminer R4, S9i, S9j, T9 and T9+. Bitmain has officially released a firmware to activate the so called “Overt AsicBoost” for Antminer S9 Bitcoin ASIC miners and will have the firmware for Antminer R4, S9i, S9j, T9 and T9+ within a week as well. This comes just a few days after the announcement that Braiins OS might actually bring users support for Overt AsicBoost. According to Braiins the activation of the “Overt AsicBoost” functionality on S9 can bring down the power consumption by about 13% which is more than welcome at the current market situation for any miner using Antminer S9 Bitcoin ASICs. Bitmain however does not officially reveal how the new firmware with “Overt AsicBoost” affects the operating parameters of the S9, though the upgrade should reduce the power consumption for sure. If you upgrade your Antminer S9 miners to the new firmware please feel free to share your feedback in the comments below.

There seems to be a new interesting addition to the product line of Bitmain’s Bitcoin ASIC miners, though apparently currently only available on their Chinese website and not on the English version. The Antminer S9 Hydro is a water cooled miner that supposedly delivers 18 THS hashrate for mining Bitcoin with 1728 Watts of power usage. Even though it is just 4 THS more than the air cooled Antmoner S9 miners, the water cooling upgrade adds other advantages besides lower operating temperatures such as improved efficiency, lower operating temperatures and lower noise levels. The new device is currently listed at 7450 Yuan which roughly translates to about $1100 USD for the whole kit that includes the miner, the water cooling and the power supply.

Specifications of the Antminer S9 Hydro:
– Hashrate: 18.0 THS SHA256 ± 5%
– Power Usage: 1728w ± 10%
– Power Efficiency: 96J / THS + 10%
– Noise Level: 45dBA @ 25°C (max: 58 dBA, min: 26 dBA)
– Complete kit: S9 Hydro, HEX water cooling kit, Antminer APW5 Power Supply

An interesting possibility is if you go for a larger custom water-cooling solution too use multiple miners connected with your own water loop for larger scale miners. While this is most definitely an interesting product and something new that people were waiting for a while from Bitmain, with the current market situation we doubt that initial sales will be that big, though again large mining operations might be more interested in these new devices.
