Bitcoin Mining Hardware: Basic Principles and Reviews

With an increased complexity of bitcoin mining, it is no longer profitable to use standard CPU or GPU powers to get income. The reason is the high level of competition on the market. Therefore, a new industry of customized bitcoin mining hardware appeared a few years ago.

Today, ASIC mining hardware (application-specific integrated circuit hardware) and GPU and FPGA (field-programmable gate array) rigs took an absolute lead in the world of cryptocurrency. This software offers incredible speed while requiring significantly less power. At the same time, there are full-complicated hardware decisions called mining farms – expensive but efficient. A number of reliable companies have presented themselves as excellent producers of the best hardware for mining. Here they are.

Most popular bitcoin mining hardware comparison

  • AntMiner S7

AntMiner S7 has been released in 2015 and now it is known as one of the most popular mining devices on the market. The reason for AntMiner’s popularity is that it offers an incredibly high hashrate for a reasonable amount of power it consumes.

S7 has 135 of 28nm BM1385 ASIC chips spread across three boards and cooled by two fans. A power supply tool that perfectly matches this device is S7 is Bitmain’s high quality 1600 Watt APW3.

  • AntMiner S9

AntMiner S9 is a more powerful version than S7. It offers amazing hashpower that reaches 14.0 TH/s. At the same time, this device stays one of the most electrically-efficient to date. It consumes 0.1 Joules per Gigahash, being 2.5 times more productive than AntMiner S7. However, S9’s price is far from cheap and starts from 2000-3000$.

  • Avalon 741

Canaan’s latest device, amazing Avalon 741, is considered as a serious rival for AntMiner. It contains 88 x A3212 16 nm chips, working at 500 MHz and achieving 7.3 TH/s hashrate, which is less energy-saving than S7, however it supports different customization options and therefore can satisfy any hardware adherent.

Bitcoin farms – ready-made mining solution

Bitcoin farms are expensive and powerful mining complexes fully-equipped with compatible elements that are already configured and ready to work. These are the most interesting solutions for farm mining:

  • CoinTerra’s TerraMiner IV

This is a water-cooled bitcoin mining hardware produced by CoinTerra. It contains ASIC chips, GoldStrike I. It is made with 28nm process technology and includes a 4U power supplement. Each ASIC chip produces up to 500 GH/s, which means that the total power of TerraMiner IV is 2TH/s. At the moment, it’s quite difficult to earn cryptocurrency, and this system will allow you to mine up to 1.1 bitcoins per day.

  • Hashfast Sierra

Hashfast Sierra is a powerful bitcoin earning machine with water cooling. The machine’s performance is based on ASIC-chips Golden Nonce. It has an in-built 4U rack enclosure and comes with two built-in Seasonic power supplies.

Sierra offers a nominal value of 1.2 TH/s, which gives approximately 0.66 bitcoins per day.

  • Fast-Hash One

Fast-Hash One series presents three versions of machines for bitcoin mining: Silver, Gold and Platinum. These are 19-inch bitcoin miners with main difference in the expansion capacities and power of the installed modules. All three machines are equipped with one payroll module with a possibility to increase them to six.

  • Black Arrow Prospero X-3

Black Arrow Prospero X-3 is equipped with 20 ASIC chips Black Arrow Minion built in 19-inch rack enclosure. The ASIC Minion chips are based on the 28nm process technology. Prospero X-3 is also equipped with an LCD screen that displays statistics and diagnostics. This equipment allows you to get power up to 2 TH/s, which might bring you about 1.1 bitcoin per day.

Mind that today’s situation on the market encourages you to get yourself powerful (and therefore, very expensive) equipment for bitcoin mining. If you are not ready to purchase one, consider buying bitcoins at the online trade markets.
