2018 Bitcoin Mining Hardware Comparison

 

Becoming a major Bitcoin miner in 2018 is a bit like setting up a shoe factory; only profitable if you’re able to compete with the Chinese. Specifically, you’ll need cheaper electricity and better access to the latest mining hardware. That’s a pretty tall order, considering that several Chinese regions are over-supplied with state-subsidised power and that the country produces most of the world’s ASIC miners, usually in close partnership with Bitcoin miners.

On top of that, the mining game got even tougher following the second halving event, which reduced the reward for successfully mining a block from 25 bitcoins down to 12.5:

Electricity costs will depend on your location and situation. Where Milli can help is by recommending the best available ASIC miners but first, we’ll need to explain a few technical mining terms.

Bitcoin Mining Hardware Jargon

Hashrate: the measure of how many attempts at solving a Bitcoin block a miner attempts per second. Obviously, the more attempts the greater the chance of solving the block and claiming the 12.5 BTC reward.

This figure was originally stated as H/s (hash per second). As Bitcoin mining hardware got faster and faster, SI unit prefixes were required:

  • Kilohash or KH/s = thousands of H/s
  • Megahash or MH/s = millions “
  • Gigahash or GH/s = billions “
  • Terahash or TH/s = trillions “
  • Petahash or PH/s = quadrillions “

TH/s is often used to state the hashrate of current generation mining hardware. PH/s is commonly used for the combined hashrate of a major mining facility or pool, as well as the total hashrate of the entire Bitcoin network (currently at a staggering 1665 PH/s).

Joule per Gigahash:  A Joule is a measure of energy, representing 1 watt over 1 second. The fewer Joules used to produce a Gigahash, the higher an ASIC miner’s electrical efficiency. As electricity is the major recurring expense of miners, this stat (often abbreviated as J/GH) is of prime importance when comparing miners.

Difficulty: with hashrate ramping up since Bitcoin’s release, one could be forgiven for expecting that blocks would be solved increasingly quickly. Difficulty is an automatic control measure which prevents that from occurring. Every two weeks, difficulty adjusts to the current hashrate so that blocks continue to be solved every 10 minutes (on average).

Profitability: this bottom-line number is calculated from the current Bitcoin price and Difficulty, your miner’s cost and hashrate and your electrical cost in fiat money per kWh. This ever-adjusting Difficulty mechanism, combined with Bitcoin’s volatile price, make calculating the future profitability of Bitcoin mining very tricky!

99Bitcoins’ mining profitability calculator is good for this purpose but if you’re serious about getting into mining, it’s recommended that you create a custom spreadsheet with inputs reflective of various exchange rate and Difficulty projections. Remember to account for probable downtime due to power cuts, hardware or software failures and the like.

Break-even point is the length of time it takes for your miner to pay for itself, if it ever does.

Pool Fees: given a total network hashrate in the thousands of Petahash, unless you control several PH/s your odds of successfully solo-mining a block are virtually nil. Mining pools are cooperative groups which combine their hash-power and distribute any rewards which the pool earns proportional to individual hashrates. Pools have different fees and reward structures which be compared here. The larger the pool, the more regular returns can be expected.

1) The Clear Winner: Bitmain’s AntMiner S9

The table results speak for themselves!

Although the S9 is four or five times more expensive than its rivals, it also mines about three to four times more bitcoins and also uses electricity far more efficiently. If your intention is to mine for profit at a small scale, at this stage the S9 represents your best shot at success. If you’re not out for profit and you’d rather mine for hobby or experimentation purposes then the S9’s hefty price tag is hard to justify.

Bitmain is currently the leading manufacturer of publically-available ASIC hardware. Their latest model, the S9, is the first ASIC to market with a 16 Nanometer (nm) semiconductor fabrication process. In layman’s terms, this means that the circuits in the S9’s BM1387 chips are nearly half the size of previous generation mining chips. This results in far greater electrical efficiency – less J/GH! – putting the S9 at the forefront of mining tech.

While other companies are developing 14nm chips, smaller fabrication processes are costly and time-consuming to establish. This means that the rate of advancement in Bitcoin mining hardware, remarkable for its speed and for being funded without major corporate involvement, will inevitably slow in the years ahead until the limits of current semi-conductor technology are reached. This means the S9 should be fairly durable for the new two or three, unless some other optimisations are developed.

Nonetheless, it’s highly unlikely that break-even will be reached in less than a year as the overly-optimistic calculator suggests. However, with cheap enough electricity, the S9 should eventually pay for itself. As more miners upgrade to the S9 (and other hardware yet to be released), Difficulty should be expected to rise. Such Difficulty increases will extend the break-even period significantly but probably not beyond 2 years…

Note that the S9’s performance varies considerably according to production batches. The initial release achieved a hashrate of 14 TH/s but currently available units achieve only 11.85 11 TH/s. As the power consumption of new models is also lower, efficiency remains similar.

The S9 will run on a standard PSU but Antminer’s 1600W APW3-12-1600-B2 is often recommended. It’s designed specifically for mining and available for an additional $140 (plus shipping), which is a pretty good deal considering its high quality.

S9 with APW3 PSU.

S9 Pros

  • Best available hashrate of 14 TH/s (early batches) to 11.85 TH/s (current batches)
  • Extremely power-efficient at roughly 0.1 Joule per GH/s
  • Works off any regular PSU (power supply unit) rated for or above 1350W

S9 Cons

  • Expensive at around $2000 (plus shipping) for the current batch
  • Not yet available as used
  • Too noisy to run near to people in a home or office

2) The Runner Up: Bitmain’s AntMiner S7

The S7 is still the most commonly found hardware in any major mining operation. In fact, it’s so popular that you’ll struggle to find a good used unit at a price cheaper than new! Of course, it can still be worthwhile to buy an S7 second-hand if it’s available locally, to save on shipping time and costs.

The S7 is in demand for a reason; it offers close to the maximum efficiency which can be squeezed out of a 28nm process, although it can be improved further through skilled modification. The S7 also has a more affordable price tag than the S9, making it an easy introduction model for prospective miners. If you want to experiment with alternative energy solutions or hardware and software mods, the S7 is a great test-bed which can also turn a profit – or at least not lose too much money.

S7 from Batch 18 with dual fans

 

The S7 is also available as a variant model, the S7-LN model, featuring a built-in 700W power supply. Less power means fewer hashes and the LN only achieves 2.7 TH/s. On the plus side, less power also means a lower price of around $291 plus less heat and noise. The LN is good for home or office use, although you’d probably want it behind a closed door. Note that the weight of the attached PSU adds considerably to shipping costs.

The S7-LN.

S7 Pros

  • Good hashrate of 73
  • Decent efficiency of 25 Joule per GH/s
  • Relatively inexpensive at $440 new (plus shipping)
  • Widespread hardware means a lot of available information and spare parts

S7 Cons

  • Overshadowed by 16nm miner and soon-to-be-released 14nm miners
  • Uses a lot of power at ~1350 Watts, which requires a high-end PSU
  • Produces considerable noise at 62dB (although the LN is quieter)
  • Hard to find second-hand

3) The Underdog: Canaan’s Avalon6

Given Bitcoin’s decentralized ideals, many are unhappy with Bitmain’s dominance of the hardware market. As Bitmain also controls 18% of network hashrate in the form of AntPool, such concerns are understandable. Unfortunately for those who’d prefer to avoid Bitmain, there isn’t an abundance of suitable alternatives at this time.

The Avalon6 from Canaan Creative is probably the best option. Although it doesn’t offer quite as much bang for the buck as an S7, it’s still a very good 28nm miner. The Avalon6 achieves a slightly lower hashrate and efficiency but uses about 300W less power. A smaller and cheaper PSU can be used.

Offsetting any PSU saving is the fact that the Avalon6 doesn’t with an inbuilt controller. It’ll need to be run from a Raspberry Pi (B, B+ or RPi2). The good news is that a single RasPi can run up to 50 units.

Pros

  • Achieves a decent hashrate of 5 TH/s
  • Reasonably efficient at 29 W/GH
  • Small form factor and quiet fan
  • Canaan has a distributor in the US for fast and inexpensive shipping

Cons

  • Avalon6 units need a separate controller
  • Pricier than the S7
  • Lower efficiency than the S7

The Bitcoin Network's Hashrate Now Exceeds Six Exahash

Featured

Last May Bitcoin.com reported on how the Bitcoin network’s hashrate surpassed four exahash per second. Just two months later on July 1st, the hashrate has increased another two exahash which transcended to a high of 6,622,799,000 GH/s according to Blockchain.info and Bitcoin Wisdom statistics.

The Exahash Era: Bitcoin Hashrate Breaks Another Record

The first week of July is showing the vast power of the Bitcoin network as miners are currently processing transactions at a whopping 5,808,727,020 GH/s. On July 1st miners pushed the hashrate up over six exahash per second reaching it’s highest point ever recorded. The mining ecosystem is far bigger than during the early days, as miners progressed from CPU mining, GPU mining, FPGA Mining, to giant warehouses filled with ASIC miners.

Bitcoin hashrate exceeds six exahash on July 1, 2017.

Furthermore, there are far more mining pools today, as there are currently 24 known pools taking a portion of the hashrate pie. Things are quite different than the early days when one single bitcoin enthusiast like Artforz captured a significant portion of the network’s hashrate. People also often forget when the mining pool Ghash.io passed the 51 percent mark in 2014, as pools in 2017 are more diversified than ever before. Only three pools command more than ten percent of the hashrate while the other 21 pools process less than ten percent.

Hashrate Has Jumped Leaps and Bounds Since 2009

The two exahash increase over the past month and a half has coincided with bitcoin’s rising fiat value, increased demand and mining revenue at all-time highs. Moreover, mining revenue has increased while the block reward has decreased since 2009’s first fifty BTC reward to 12.5 BTC per block, with the reward expected to continue to halve approximately every four years. In September of 2013, the hash rate had only hit one petahash per second, so the hashrate is expanding significantly yearly. The six exahash record also comes only one year and six months after the network topped one exahash or 1000 petahashes per second.

Miners revenue at an all time high as miners receive 12.5 BTC per block.

A Pure and Voluntary Economic Incentive Continues to Amass Significant Power

The exponential rate growth will someday surpass the exahash era (exabytes) and could reach zettabytes or even yottabytes per second. This will likely take many years as 500 exabytes is only one-half of a zettabyte.

The record-breaking six exahash is another landmark achievement for the Bitcoin network as the innovative protocol has reached many milestones this year. It’s an amazing feat to see such power obtained without a large corporation or government backing. All of the hashrate power is commanded by miners choosing to join the decentralized system voluntarily, all thanks to the economic incentive of the block reward plus transaction fees.

Bitcoin Cash Now Commands Over 20% of BTC's Total Hashrate

Mining

On August 21 the Bitcoin Cash (BCH) network got a lot more active as the large mining pool Antpool has pointed some of its hashrate towards the BCH chain. According to data, the forked chain’s hashpower has spiked exponentially, and BCH hashpower is roughly a quarter (approx. 2 exahash) of the BTC hashrate at the time of writing.

Antpool Begins Mining Bitcoin Cash

As news.Bitcoin.com recently reported the bitcoin cash (BCH) blockchain has sped up quite a bit over the past five days. There are a few factors behind this, such as the price of BCH rising exponentially and reaching $960, making mining over 140 percent more profitable on the BCH chain on August 19. Since then the price has dipped quite a bit on Monday, August 21, as one BCH hovers roughly just above the $600 price range at press time. This makes BCH miner revenue only 69 percent more profitable than BTC. Currently, bitcoin cash miners have processed 2171 blocks since the hardfork, and are steadily catching up to the BTC chain which is leading by 794 blocks.

Bitcoin Cash hashrate exceeds 2.2 exahash on August 21.

Just recently the mining pool BTC.com started mining BCH on Sunday, August 20 becoming the next pool to join after Bitclub. Following this, the Bitcoin network’s largest mining pool, Antpool, pointed some of its hashrate towards mining BCH as well. Antpool’s Jihan Wu previously stated that once another Segwit supporting pool joined in on BCH mining, Antpool will follow suit. Over the last 144 blocks, Antpool has captured 2 percent of the hashrate since it started 24-hours ago. BCH supporters are also waiting for the mining pool BTC.top to point some hashrate towards the chain as they announced they would start doing so on Monday the 21st. Additionally, many miners are coin-jumping between BTC & BCH as mining pools have added switchable interfaces on their dashboards.  

The Mining Operation Batpool Dedicates Hashrate to Bitcoin Cash While the Mystery Hashrate Drops Below 50%

While waiting for other miners to jump aboard the bitcoin cash mining train, BCH supporters got another surprise. On August 21 at approximately 10:25 am EDT the mining pool Batpool mined BCH block 480667. Now a total of six ‘known’ mining pools are mining the BCH chain, and the ‘unknown’ hashrate is currently mining less than 50 percent of the network. Further, there has been lots of discussions about the mystery mining power, and many believe the hashpower does not represent one miner. According to many BCH supporters, who are currently asking data sites like Coin Dance to update their pie chart, there are three ‘unknown miners’ making up the majority share of BCH hashrate. The differences between the three ‘unknown’ mining pools can be seen within the coinbase data on each block.

Bitcoin Cash hashrate distribution as of August 21, 2017, with three new known mining pools including Antpool, BTC.com, and Batpool.

At the Current Trajectory, the BCH Network’s Difficulty Will Retarget Higher

Now with a lot more hashrate pointed at the BCH chain, the network’s difficulty will retarget higher at the current rate in roughly two days. If the price remains low and the hashrate stays the same or increases, BTC mining may become more profitable to mine at this time. This could very well lead to miners switching back and forth between both chains for competitive profits. Since some hashrate has shifted to the BCH chain, there has been a significant drop in hashrate for the BTC chain. For instance, on its top around August 16 the Bitcoin network had commanded 9 exahash, but at the time of writing on August 21, the hashrate was only 5.9 exahash.

Bitcoin (BTC) Hashrate drops significantly since last week.

At the moment many cryptocurrency spectators are watching the competition between these two chains very closely. Further, besides watching BCH & BTC, there is still a lot of bickering happening back and forth between Core developers and Segwit2x supporters. With all this action taking place there’s no doubt there will be a lot going on over the next few weeks in Bitcoin-land.

What do you think about the bitcoin cash hashrate growing exponentially while BTC’s network sees a drop? Do you think more miners will join the BCH chain or do you think miners will switch back to BTC soon? Let us know what you think in the comments below.
