Innosilicon A8 CryptoMaster CryptoNight ASIC Miner

A8 CryptoMaster Miner

The A8 CryptoMaster is Innosilicon's first entrance into the CryptoNight mining market.  You may know Innosilicon initially from is first ASIC miner, A4 Dominator.  This miner primarily support the Litecoin network.  Next we had the A5 Dashmaster that support the X11 algorithm which Dash is the most popular coin to be mined.  The A8 CryptoMaster is used to min Monero, an alt-coin that is growing in popularity and support.  We have proof positive that this is the case with companies spending the money on research and chip development to make a fully functional miner.

The design is very similar to an Antminer except that this unit is double the width of a standard Antminer.   The A8 has a massive eight (8) hashboard spread across the aluminum case.  It has the same standard controller board and four cooling fans.   Web-based interface for the miner and a simple setup via a webpage to program your pool information and monitor the miner's hashing progress.  The A8 CryptoMaster products around 160kh/s while only consuming 350 watts of electricity.  At 208 volts you can run about 10 miners on a 20-amp circuit.

Canaan AvalonMiner 821 Bitcoin Miner

AvalonMiner 821 Bitcoin Miner

This is the newest ASIC miner from AvalonMiner, the Avalon 821.  This is the successor to the Avalon 741.  The Avalon 741 clocked in at 7.3Th/s while consuming 1,150 watts.   The A8 now produces a whooping 11.5Th/s for only 1,200 watts.   This is over a 60% increase in hashing power with only a ~100 watt increase in power consumption.  This is good news for AvalonMiner owners that are looking for an upgrade that isn't from Bitmain.   The Avalon design philosophy is a little different that the Antminer units.   The 821 has a single fan design that uses an exhaust-only fan.  

One drawback to this design is the placement of the temperature sensor on the unit.  It is critical that you have a climate-controlled environment that keeps the unit below the temp threshold.  The S9 miners are more resilient in high temperature environments.  Once temps are under control, the 821 is a very reliable unit and a quality choice when purchasing a Bitcoin miner.   The unit comes with two hashing boards with four PCI-E (6 -pin) connectors per board.   Now in a very different design than other miners on the market, the Avalon 821 does not have an on-board controller.  Instead, they use a Raspberry Pi as a controller and proprietary cables to communicate with the miner.  On the plus side, the controller can support up to 15 miners per Pi.  To accomplish this, you daisy chain the miners together.

The Pi provides a basic Linux-based web interface.  Nothing flashing but sufficient for what the modern miner needs from a miner administration standpoint.

Bitmain Antminer D3 - X11 ASIC Miner

Antminer D3 Miner

The Antminer D3 is Bitmain's ASIC miner for the X11 hashing algorithm.    X11 is growing in popularity so it is natural that the larger hardware manufacturer of crypto-currency miners has decided to enter the market with their commercial offering.  The D3's design is in the same line of all the Antminers since  the S7 miner.  The length is very close the S9 miner.  The miner has the same configuration of: three hashing boards, controller board, two fans and an aluminum case.   The units is a little higher than an S9 but outside of that, basically the same.

The web interface is the same Linux powered setup you find in all of the Bitmain offerings.  There are five mineable coins for the  X11 protocol.   DASH by far is the coin that almost everyone is mining with these units.   With the growing popularity of this miner, we could see the difficult spike significantly when this launch.  Each units takes 1,200 watts a piece.   On a 20-amp you can safely run two miners and potentially three miners but please note you will be 1.3 amps over the normal de-rating of 80% of the breakers maximum capacity.

Overall another solid offering from Bitmain and should do a good job mining for X11.

Bitmain Antminer S9 ASIC Miner

Antminer S9 Bitcoin Miner
The S9 Bitcoin miner from Bitmain is their newest offering in their hardware lineup.   Released in June of 2016, they are coming in a number of models.  The Antminer S9 miner models are available in different speeds based on the batch order.   Hashing speeds are: 14Th/s, 13.5Th/s, 13.0Th/s, 12.0Th/s and 11.5Th/s.  At the wall, the S9 miner consumes about 1,330 to 1,450 watts under full hashing load.  

The design is very similar to the Antminer S7 unit.  The S9 is a little longer than the S7 but outside of that, basically the same.   They both share the same administration interface that the entire Bitmain miner family uses.  It is a very simple setup to get the unit mining, estimated setup time is under 5mins once you have it plugged in and on your network.

The performance increase is amazing compared to the S7 miners.  With very similar power consumption, this is a major upgrade from Bitmain and these will become the majority of Bitcoin SHA256 mining power on the Bitcoin network.  Out of warranty service is still very high  with only a few parts to support or replace in the event of damage.   

Parts normally needing service after 12-18 months of service are:  (3) Hashing Boards, Front or Rear Fans and Control board.   Normally you will see one or both fan bearings go out and if they are hosted in a high temperature environment, you will see a hash board failure potentially.   Control board and PSUs have very low failure rates.
