The newest NBMiner 21.4 update comes with further improvement in the performance for Grin31 mining (Cuckatoo31 algorithm), though slight one from what we are seeing, the miner is still probably the fastest Nvidia GPU miner for Cuckatoo31. There is also performance improvement for Grin29 (Cuckaroo29) and AE (Aeternity) on Nvidia RTX cards and the current level of performance is almost on par with other competing miners in terms of hashrate on GTX 1080 Ti GPUs, though the latest GMiner 1.36 still has a slight performance advantage on GTX 1080 Ti under Windows at least.

NBMiner v21.4 also fixed Grin31 compatibility on Windows 7 with 8GB video cards and comes with a new option to reduce the range of power consumption by multi-gpu rig (--cuckatoo-power-optimize). The use of this option could prevent power spikes from causing problems with power supplies that are near their limit and thus can help improve mining system stability, though there may be some drop of mining performance as a result, so do try the option and see it it helps or not improve system stability and ho it affects mining performance in your case.

We remind you that the NBMiner is a closed source GPU miner for Nvidia CUDA that is available for both Windows and Linux operating systems and it has the following developer fee built-in: tensority + ethash – 3%, tensority (Pascal GPUs) – 2%, tensority (Turing GPUs) – 3%, ethash – 0.65%, cuckaroo29 and cuckatoo31 – 2%.

The new Bitmain Antminer Z11 ASIC offers a hashing power of 135 KSol/s for the Equihash algorithm used by ZCash (ZEC) and other crypto currencies and is essentially the successor of the Antminer Z9 from the last year that offered 40 KSol/s and the Antminer Z9 mini that was just 10 KSol/s. The Antminer Z11 uses Bitmain’s latest proprietary 12nm chip, which is made using advanced Bare Die molding technology for better heat dissipation and has a power-efficiency of 10.50 J/KSol, so it is with significant improvement over the older hardware. The recommended power supply for this miner is 1800W, though the actual like the APW7 PSU from Bitmain, though the actual power consumption is lower (1418 W power consumption claimed). The current price of the Antminer Z11 is $1242 USD and shipping should start around the end of April (20-30).

Bitmain has made available a new 96KHS ASIC miner for Bytom (BTM) called Antminer B7 as a successor of their Antminer B3 ASIC from about a year ago that was offering just 780 H/s mining hashrate with 360 Watts of power usage. After the release of the B3 ASIC last year the development of a much faster GPU miner for Bytom’s Tensority algorithm began and currently most recent GPUs are delivering quite good hashrates for BTM mining. The new Bitmain Antminer B7 ASIC is going to put out a more serious competition however for anyone interested in minig BTM.

The new Bitmain Antminer B7 ASIC is currently only available on the Chinese website of Bitmain and promises 96 KHS hashrate with just 528 Watts of power usage, so tough competition for GPUs in term of hashrate and power usage. The price of the new Antminer B7 ASIC miner is currently set at 9900 Chinese Yuan or a little less than $1500 USD, but ordering the device to Europe or US can easily bump the price to over 2K. When you look at the current low profit numbers however you may very quickly decide not to invest in these new ASIC miners however…

The most recent version of the fastest NBMiner 21.0 GPU miner for Bytom (BTM) is capable of delivering about 3.4 KHS for a single GTX 1070 Ti, 5 KHS for a single GTX 1080 Ti and 11.5 KHS for GTX 2080 GPUs according to the official information from the developer. This means that a 8x GTX 2080 GPUs mining rig would be needed in order to deliver hashrate similar to that of the Antminer B7, but it will end up significantly pricier and with higher power usage.
