15 THS Canaan AvalonMiner 851 is Now on Sale

27, Aug 2018

While we are still waiting for the upcoming Avalon A9 Bitcoin ASIC miners that will be based on 7nm technology, Canaan Creative has apparently started selling AvalonMiner 851… the successor of 841. The new AvalonMiner 851 is based on the same 16 nm A3210HP ASIC chips that the 841 uses, though apparently there have been some optimizations in order for the new model to reach 15 THS up from 13.6 THS for the 841 version. So with Canaan AvalonMiner 851 you get 15 THS hashrate for Bitcoin mining with 1450W of power usage, allowing for a slightly better hashrate density, but not much of an efficiency improvement in terms of power usage. It is interesting to note that at the official Canaan website the AvalonMiner 841 is listed at $425 USD while the 851 is at $450 USD or just 25 dollars more, though wit distributors the price difference would be higher.

Bitmain Antminer S9 Hydro 18 THS Water Cooled Bitcoin ASIC Miner

25, Aug 2018

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.

Baikal Miner BK-D, a New First Dual Mining ASIC Miner

13, Jun 2018

Does somebody still remember the Gridseed ASIC miners that could dual-mine BTC and LTC a few years ago? Well, it seems that a new dual mining ASIC miner is coming from Baikal Miner that is capable of mining two different algorithms at the same time. The new Baikal Miner BK-D supports Blake256R14 or Blake256R8 as first algorithm with 280 GHS hashrate and LBRY or Pascal as second algorithm with 70 GHS. You can have the miner mine any of the two pairs of algorithms simultaneously at 1100W of power usage total.

There is still no information about pricing and availability however, Biakal Miner have just announced their new device and it is yet to even become listed on the official company website. Doesn’t seem like too profitable at the moment, so it is more of an interesting product as we did not have dual miners in the fork of ASICs for quite some time. Availability and pricing of the device can make all the difference, so we need to wait and see what they will be. With a price of $2100 USD without a PSU it seems even less interesting…
