The Rise of the Avalon 721 Bitcoin ASIC Miner - Review - 1st Mining Rig

Ter this review I’m going to talk about the Avalon 721, which is an significant addition to Bitcoin mining hardware.

Some columnists and hardware manufacturing still voorkeur that BTCs can be mined with GPUs. Big companies like AsRock and Biostar write that their fresh motherboards are meant for Bitcoin GPU mining equipments. That’s wrong on so many levels!

This kleintje of misleading advertising created a thick confusion about Bitcoin mining. Let mij commence this review by reminding that Bitcoin cannot be mined using GPUs anymore. It is no longer profitable at the point that GPUs won’t even voorkant the cost of electric current they need to run. For GPU mining cryptocurrencies check ZCash, Ethereum,Monero etc.

The Avalon 721 Bitcoin ASIC Miner Review

The Avalon 721 is an ASIC that is being manufactured by Canaan Creative, a China-based company. The Avalon 721 wasgoed announced the 7 th November 2016, and since then thousands huis miners purchase it, making it the 2nd most popular Bitcoin ASIC after the Antminer.

Here are its specs:

  • Hashrate: 6 TH/s
  • Power Draw: 850-1000 W
  • 72x A3212 16nm chips
  • PSU output pins: 8 x 6PIN PCIe power connectors
  • Dimensions: 340 mm x 136 mm x 150 mm
  • Operating Temperature: -5 °C to 40°C
  • Netwerk weight: Four.Three kg

The Avalon 721 can be connected to other ASICS of the same kleintje by using a controller adaptor, which is manufactured by Canaan too. The maximum number of ASICs vanaf cluster is five, resulting ter a total hashrate output of 30-32 TH/s.

It is worth mentioning that the power draw of the Avalon 721 wasgoed decreasing overheen time. It embarked with 1000 W, but the fresh upgrades made the ASIC more power-efficient.


Most beginners are worried whether it is safe to get an ASIC. Their concerns are understandable since the volatility of cryptocurrencies is indeed scary. I do share the same concerns but on a lower degree. Personally, I am aware that investing into mining gear is risky. However, I do have my reasons to believe that cryptocurrencies are less risky than they might seem at very first glance.

Let’s not dive into financial explanations here – there are many objective reasons why cryptocurrencies are more likely to become the fresh gold ter the near future. But since we’re talking about trends and profitability, let mij give you an example:

Back ter December 2016, the televisiekanaal profit from an Avalon 721 wasgoed $37.59/month, which meant that the ROI of the ASIC wasgoed 24 months. Spil for today, the same ASIC proefje will earn you $ 103.98/month. This is due to the price of Bitcoin permanently growing due to the growing request on the coin.

While the price of BTC fluctuates on a daily poot, its overall direction is up. It’s bot like this for years and there are no objective reasons why it should switch anytime soon.

Avalon 721 vs Antminer S9

Even almost two years after the Avalon 721 wasgoed released, people keep debating whether the Antminer S9 is a better option. Despite seemingly rock-solid arguments and bold claims, there is no definite winner te that contest.

You see, the Antminer S9 does outperform the Avalon 721 hashrate-wise, however, the Avalon 721 costs twice less. Crypto coins cannot be used spil fiat currency for all your needs, at least not yet. Therefore, depending on your needs, investing two and half grands into cryptocurrencies might be too much. Of course you can sell the mined BTCs afterwards, but that would require extra time and dedication.

Before to proceed further, please share this thanks!

Besides that, the Avalon 721 has 16nm hardware which will more likely ensure longer lifetime to the ASIC. The overall build quality of the Avalon 721 is better than of the Antminer S9. Te addition to that, there are many positive reviews about Canaan customer service, something that cannot be said about Bitmain. Last but not least, the Avalon 721 has quieter ventilatoren than the Antminer S7/9.

All of this explains why people keep debating which one of the two giants is better. The takeaway is elementary – get the one which meets your expectations, if you’re after quality, petite investments and less risks, go for the Avalon 7. Otherwise, get the Antminer.


Not long ago, Canaan released a newer version of the Avalon 7 – the Avalon 741. It costs about $ 700, outputs 7.Trio TH/s and can be purchased from Canaan’s official webstek.
