ASIC Miners

ASICs are the most effective tools for mining cryptocurrencies, offering the highest hash rates while consuming less power than GPUs. Below, we’ve provided information about the very latest ASIC miners in 2018, including technical specifications, pricing and details of where they can be purchased.

 

Antminer Z9

Antminer Z9

The Antminer Z9 is the latest ASIC from Bitmain. Unsurprisingly, they’ve hailed it as the most efficient, most powerful ASIC currently available. Designed for use on the Equihash network, customers will be able to mine for cryptocurrencies such as Bitcoin Gold, Komodo and ZCash. The second batch of Z9s are scheduled for release in September 2018.

 

Technology

As is the case with all Bitmain ASICs, the Z9 features aluminium alloy heat sinks and computer-controlled fans to help further with cooling. An external power supply is required to power the IO board – an ATX PSU with 7 six-pin PCIE connectors is recommended by the manufacturer. A 10 amp power supply must also be purchased.

Antminer S9

Hailed as ‘the world’s first consumer grade 16nm ASIC miner’, the Antminer S9 succeeds the popular S7 series and is three times more powerful. It is, at present, the most efficient crypto miner on the market, able to generate 13.5 TH/S. Although it was built primarily for Bitcoin, the Antminer S9 can also be used to mine for any currencies using the SHA-256 algorithm.

 

Technology

The S9 ASIC miner comprises 189 BM1387 chips, which have been built using TSMCC’s 16nm process node. Its control board features a Dual ARM Cortex A9 processor with CoreSight and includes Gigabit Ethernet to help ensure the instant submission of mined blocks.

To aid with cooling, the S9 heat-sinks and case are made from high-grade Aluminium alloy. Two computer-controlled fans also assist with heat extraction, replacing hot air at the required pace.

ASIC mining hardware often requires a separate PSU. And so it goes with the S9 which needs a power supply unit of at least 1600w in order for it to operate reliably.

This must be connected to the 3 PCI-e connectors on each hashing board as well as an additional 6pin PCI-e connector on the IO board. Although multiple PSUs can be used for both the hash boards and control board, the use of a single unit is recommended.

Specifications

  • Energy efficiency – 0.098w/Gh
  • Power consumption – 1323W
  • Hash Rate – 13.5 TH/s ±5%
  • Algorithm type – SHA-256
  • Form factor – 35cm (L) x 13.5cm (W) x 15.8 cm (H)

Pros

  • Most powerful, energy efficient ASIC on market
  • High hash rate
  • 90 day warranty when purchased from Bitmain

Cons

  • Expensive
  • Separate PSU required

Avalon 821

AvalonMiner 821

The AvalonMiner 821 is an eighth generation Avalon ASIC which uses an A3210 – the very latest 16nm Bitcoin chip. Consequently, it is able to perform far more efficiently than the popular 741, offering a hash rate of 11TH/s, while drawing 1200w.

 

Technology

As with most Avalon ASICs, the 821 can be connected to another five AvalonMiners by using the same type of AUC3 USB converter found on the 741 – this results in a formidable hash rate of 22TH/s. The same Airform Cooling Technology is also employed to help ensure effective heat management. The 821 does not feature a built-in controller so any purchase should include either an AvalonMiner or Rasberry Pi controller. A separate power supply of at least 1200w is also required.

Specifications

  • Energy efficiency – 0.109J/Gh
  • Power consumption – 1200W
  • Hash Rate – 11TH/s, -5% ~ +10%
  • Algorithm type – SHA-256
  • Form factor – 37cm (L) x 15cm (W) x 13.6cm (H)

Pros

  • More efficient than the 741
  • Effective cooling system

Cons

  • PSU sold separately

Antminer T9+

Antminer T9+

The Antminer T9 was the first ASIC to be based on the 16nm process node. Each unit features 162 x BM1387 chips and a Dual ARM Cortex A9 microprocessor with CoreSight. Although not quite as powerful as the Antminer S9, the T9 is still able to hold its own with a decent hash rate of 11.5 TH/s. Moreover, the T9 is considered by many to be more reliable than its more expensive successor.

 

Technology

The T9 comprises customized heat sinks made from aluminium alloy. As is the case with the S9, two high-speed fans are installed either end of the unit – each one is computer-controlled which further improves heat extraction rates. A separate power supply is required for the T9 – Bitmain recommend purchasing the Antminer APW5 or APW3 in order to achieve the best performance at the most energy efficient rate.

Specifications

  • Energy efficiency – 0.125J/GH
  • Power consumption – 1432W
  • Hash Rate – 11TH/s +5%
  • Algorithm type – SHA-256
  • Form factor – 32cm (L) x 12.5cm (W) x 19cm (H)

Pros

  • Reliable
  • Relatively affordable
  • High hash rate for the money

Cons

  • Not as efficient or powerful as the S9

Antminer X3

Antminer X3

The Antminer X3 is a Cryptonight mining ASIC from Bitmain which has been developed to mine currencies such as Monero. With a minimum hash rate of 220KH/s, the X3 vastly outmatches the CPU and GPU hardware that’s typically used to mine CryptoNight. It’s also extremely energy efficient, consuming just 550W from the wall.

While the X3 is undoubtedly powerful, Monero recently revealed plans to change their PoW algorithm so that it’s ASIC-resistant. Although there are numerous currencies which use the same algorithm such as Aeon and Dash, exercise caution before investing.

 

Specifications

  • Energy efficiency – 1.6 J/MH
  • Hash rate – 220KH/s
  • Algorithm type – Cryptonight
  • Power consumption – 550W
  • Form factor –12.5cm (L) x 20.8cm (W) x 32.1cm (H)

Pros

  • Energy efficient
  • High hash rate

Cons

  • Separate PSU required
  • Expensive
  • Uncertainty about Monero

Antminer S7

Antminer S7

Released in 2015, the Antminer S7 remains one of the most popular ASIC miners – so much so that there have been 19 iterations. Although nowhere near as powerful as the S9, the S7 still offers a good hash rate compared to the amount of power it consumes. It’s also much cheaper than its successor which has led some crypto miners to building rigs with multiple S7 ASICs in order to achieve the same hash rate. With that said, since the release of the S9, this particular ASIC is becoming increasingly difficult to source.

 

Technology

The S7 is powered by162 x 28nm BM1385 chips which are mounted on three boards. Cooling is achieved with two push-and-pull fans (for most models). Its metal casing also comprises a tongue and groove system that allows for the easy assembly of multiple ASIC units, side-by-side. Apart from the S7-LN model which features its own 1000w PSU, most versions require a separate power supply unit of at least 1300w.

Specifications

  • Energy efficiency – 0.25 W/Gh
  • Power consumption – 1293W
  • Hash Rate – 4.73 Th/s
  • Algorithm type – SHA-256
  • Form factor – 30.1cm (L) x 15.5cm (W) x 12.3 cm (H)

Pros

  • Relatively inexpensive
  • Excellent support
  • High hash rate for the price

Cons

  • Superseded by the R9 and X3
  • High-end PSU required
  • Difficult to Source

Antminer R4

The Antminer R4 is a consumer-grade ASIC which was released in 2017. Boasting an energy efficiency of 0.098 J/GHs and a hash generate rate of 8.6 TH/s, it’s aimed squarely at home-based crypto miners. As far as overall performance is concerned, the R4 sits between the Antminer S9 and S7 and offers a good solution for miners with medium budgets.

 

Technology

The Antminer R4 features the same BM1387 chips found on the S9 although not as many (126 v 189). It’s also been specifically designed to operate as silently as possible and includes a rotary blade fan that’s said to reduce noise levels by up to 50%.

The control board, which is specially-designed to reduce latency, makes use of a Xilinx ZYNQ-7000 system-on-a-chip and a dual-core ARM Cortex A9-based Application Processor Unit. The R4 also consists of a slimmed down form factor that allows for convenient placement.

The Antminer needs a separate power supply unit – Bitmain recommend their custom-made APW5 which features a dynamically-controlled fan for the further reduction and operates on both 220v and 110v.

  • Energy efficiency – 0.098 J/GHs
  • Hash rate – 8.6 TH/s
  • Algorithm type – SHA-256
  • Power consumption – 845W
  • Form factor – 51.5cm (L) x 10cm (W) x 22.2cm (H)

Pros

  • Silent runner
  • Energy efficient
  • Simple User interface
  • Good hash rate

Cons

  • Expensive

Antminer D3

Antminer D3

The Antminer D3 was developed for DASH mining and works on the X11 proof of work algorithm. It has an efficiency rate of 1.6 J/MH and can generate up to 17 GH/s while drawing 1200W from the wall. As with most ASICs from Bitmain, the D3 offers a strong degree of stability

 

Technology

The D3 features three hash boards and 180 x BM1760 chips. There are three PCI-E ports, of which all are required for the connection to a separate ATX Power supply unit. All in all not a bad investment and an ideal ASIC miner for altcoins. Forget about currencies with higher difficulty levels though.

Specifications

  • Energy efficiency – 1.6 J/MH
  • Hash rate – 17GH/s±5%
  • Algorithm type – X11
  • Power consumption – 1200W
  • Form factor – 32cm (L) x 13cm (W) x 19cm (H)
