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.

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.

Another update for the NebuTech BTMiner Nvidia GPU miner to version 10.0 for mining Bytom (BTM) that brings another significant performance boost by increasing the hashrate provided by the miner with about 30% or even more compared to the previous version 9.0, depending on what kind of Nvidia GPUs you have in your mining rig of course and the settings they are running at. Anyway, this is a really big performance boost to the miner, so if you are mining Bytom (BTM) with your Nvidia GPU mining rigs you must definitely update to the latest version to take advantage of the increased hashrate. We remind you that the NebuTech BTMiner is a closed source Bytom (BTM) GPU miner for Nvidia CUDA that is available for both Windows and Linux operating systems and it has a 3% developer fee built-in.
