Bitmain may not have a stock of their newer 7nm chips for the faster SHA256 ASIC miners, but they apparently have more of the old chips to push new miners, so hence the Antminer S9 SE is born. It is a 16 THS Bitcoin ASIC miner with built-in power supply(?) and a 1280W power consumption (80 J/TH power efficiency). The price of the new Bitmain Antminer S9 SE ASIC miner is set at $351 USD with the first batch to go on sale today scheduled for shipping in 21-31 July, 2019.

Although this may be far from the latest offerings in terms of hashrate, miners like the “new” Antminer S9 SE might be interesting for some people due to their low price and if they can be combined with low priced power it might be a good opportunity. The used market for Antminer S9 ASICs is booming lately due to the price of Bitcoin going up, so we see demand for the new miner for sure. Of course it also depends on the amount of units that Bitmain can deliver…

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.
