Bitmain Has Announced New 7nm BM1397 ASIC chip for SHA256 Mining

18, Feb 2019

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…

NBMiner 12.0 – The New Name of the NebuTech BTMiner for Bytom (BTM) Mining

19, Dec 2018

After a while with no updates the NebuTech BTMiner is back with a new name, a lot of changes and new functionality under the name NBMiner. The miner is still intended for mining Bytom (BTM) on Nvidia GPUs and the latest version brings a lot of new stuff with the miner becoming more like other miners you are already used to with. Apart from improved BTM hashrate, added support for backup mining pools and a decreased developer fee to 2% (down from 3%) the new miner comes with a BTM+ETH dual mining mode as well as XMR+ETH, thiugh it seems that there are some issues with that as version 12 temporary removes the XMR support, but it should be back. We remind you that the NebuTech BTMiner is a closed source Bytom (BTM) GPU miner for Nvidia CUDA (drive version to 377 or newer is required) that is available for both Windows and Linux operating systems and it has a 2% developer fee built-in.

Bitmain with Two New 7nm ASic Miners – Antminer S15 and T15

9, Nov 2018

Bitmain has announced its next-generation 7nm miners – Antminer S15 and Antminer T15 and is already taking orders for the new devices with estimated shipping time for the second half of December. Both new Bitcoin ASIC miners have two different operating modes – a high-performance one for maximum hashrate and an energy saving mode that offers better energy efficiency with lower power usage and reduced hashrate. Antminer S15 is available for $1475 USD with a limit of 2 miner per user and Antminer T15 for $913 USD with a limit of 50 miners per user. The new miners do come with a built-in power supply included in the price, but be aware that apparently this PSU is only for 220V input power and also the output voltage is not the standard 12 used previously, so finding an alternative power supply may turn out to be a bit of a challenge.

The Antminer S15 high-performance mode can achieve a hash rate of 28 TH/s with a power efficiency as low as 57 J/TH (1596W); its energy-saving mode can improve power efficiency to 50 J/TH while maintaining a hash rate of 17 TH/s (850W). The Antminer T15 high-performance mode sees a hash rate of 23 TH/s and a power efficiency as low as 67 J/TH (1541W). Its energy-saving mode can improve power efficiency to 60 J/TH while maintaining a hash rate of 20 TH/s (1200W). The new Anminer ASIC miners come with a new high conversion power supply APW8 that has a non-standard 16-18V high-voltage output, so they can effectively reduce the power loss during the power conversion process, helping mining farms save on electricity costs, or so Bitmain claims as a reason to include the new power supply module as a part of the miner. The only problem is that the new power supplies are not designed to operate on 110V power grids and that can present a challenge for some regions that do operate on these.
