Bitmain, the manufacturer of Antminer series of mining hardware, remains the World’s leading ASIC manufacturer. It is estimated that their hardware currently accounts for 70 percent of all Bitcoin mining hardware in the market.

Bitmain is known to create Antminer series of mining hardware that mine at unmatched speeds. In most cases, anyone looking to mine Bitcoin will be recommended an Antminer series of mining hardware.

Review: Avalon 721 VS Antminer S9

Comparison of two most popular bitcoin asic miners

As the difficulty to mine Bitcoins grows harder and harder, the ability to make profits requires a powerful and efficient miner hardware. With this in mind, in 2016, Bitmain released its most powerful miner, the Antminer S9, with a hash rate of 13.5 TH/s.

Similarly, Canaan – the company responsible for introducing the first ASIC chip to Bitcoin mining introduced their new miner to the market in 2016, the AvalonMiner721.

The Canaan AvalonMiner 721 is an excellent miner all round, providing solid performance and support, using the 16nm chip process. Even its software is simple-to-use, coupled with a robust, feature-rich advanced console.

The AvalonMiner 721 was announced on the 7th November 2016 and since then thousands of miners purchased it, making it the second most popular Bitcoin ASIC miner after the Antminer S9.

To compare the two machines and see how AvalonMiner stacks up to Antminer, let’s put them head-on in a comparison of several parameters.

AvalonMiner 721 is more reliable than the S9

The AvalonMiner 721 from Canaan was a welcome addition to the Bitcoin mining ecosystem. The AvalonMiner 721 is one of the most reliable devices. Furthermore, its design is also top-notch, with a quality case, cooling system and robust board design.

The product is good for both home and data center users, showing a solid stability in both the board design and ASIC design. It would not break-down easily.

However, Antminer S9 is a bit different story. While the device is the fastest device on the market, it has had its share of reliability issues. There have been several instances when the product has broken down, with comments like “out of the 12 S9’s I have bought from Bitmain, 4 of them have needed repair” flooded in the marketplace.

It was the reliability concern that led Bitmain to release their new Antminer T9, fixing those reliability concerns.

Both the devices have solid design

The AvalonMiner 721 comes in an aluminium case that houses the boards and fan. Additionally, the fan operates by pulling the air over the boards.

The Antminer S9 has a sturdy design and cooling mechanism. It is easy to maintain and service. Additionally, as long as the device is kept in a place with good ventilation, it performs at good speeds.

Power consumption is better on the S9

Antminer S9 Power overview

The Antminer S9 works out to 0.1 Joules per Gigahash (1350 watts / 13,500 GH/s)

While in absolute terms, the AvalonMiner 721 uses lesser power consumption at 1,050 watts, as compared to Antminer S9’s 1,350 watts; however, in terms of efficiency, i.e. Joules per Gigahash, the Antminer S9 works out to 0.1 Joules per Gigahash (1350 watts / 13,500 GH/s) which is comparatively 60 percent lesser consumption than the AvalonMiner 721.

In case of AvalonMiner 721, the Joules per Gigahash are higher at 0.16-0.17 Joules per Gigahash (950 watts / 6,000 GH/s)

Customer support is better with AvalonMiner 721

The Canaan customer service has several positive reviews in the market, as opposed to Bitmain which takes a lot longer to support its customers.

There are several cases of customers who have shifted from Bitmain to Canaan, especially due to the latter’s better customer service. The customer satisfaction index is also high for Canaan, as customers are more likely to stay with the company.

On the other spectrum, Bitmain has a reputation for delayed shipments, longer service times and slow response rate.

AvalonMiner 721 is less noisy than the S9

The AvalonMiner 721 is less noisy, and comes in at 49 dB at 4 feet, whereas the Antminer S9 comes in at 79 dB at 4 feet.

AvalonMiner 721 costs less than the S9

The AvalonMiner 721 costs US$850, while the Antminer S9 costs US$1,415. Besides, due to limited availability in the market, its cost goes upwards of US$1,600-1,700. Depending on the availability of the Antminer in the market, it may cost twice as much as the AvalonMiner 721.

Antminer S9 is the industry leader with twice the hash rate of 721

Antminer S9 outperforms all other mining devices on the market. In terms of hash rate, the Antminer S9 is the most powerful machine with a hash rate of 13.5 TH/s, more than double that of AvalonMiner 721’s 6.0 TH/s.

The verdict

The AvalonMiner 721 is appealing to a home miner who wants to mine Bitcoin. If you can relate yourself to any of the following scenarios, you might want to go with an AvalonMiner 721:

  • If you want to get set to mining quickly, and you place a higher significance to reliability than efficiency, then the AvalonMiner 721 is a reasonable choice
  • If you are money-conscious and have a limited budget, then AvalonMiner 721 is the right choice for you
  • If you don’t pay the cost of power and just want to set up a strong, well built miner, then the AvalonMiner 721 will fit you better

Else, if the fastest and most efficient device is right for you, then go ahead with an Antminer S9. It is also anticipated that the new batch of Antminer S9’s will be more reliable.
