Antminer S9/T9/S7/S5/S3 Bitcoin Miners Reviews & Comparison

Antminer S9/T9/S7/S5/S3 Bitcoin Miners Reviews & Comparison

With recent Bitcoin price increases, many users are looking for a way to make money through Bitcoin. And one of the main methods to do that is through mining Bitcoin. In this article we review and compare top mining hardware along a method to calculate how much profit could be made through using any of these tools.

Antminer S9

Pricing at a little less than $2,500, Antminer S9 is currently the most powerful Bitcoin miner made by the manufacturer company. According to the maker company, Bitmain Technologies, Bitcoin miners could get the best ROI from this product. 

Here are key features of S9:

  • Without the need for a separate host computer – built-in web management portal
  • Recommended power supply: AntMiner APW5/APW3 (sold separately)
  • 098 J/GH±7% (currently the most power efficient miner)
  • Power consumption: 1323W±7%
  • Hash rate: 13.5TH/s±7%
  • Default frequency: 600M
  • Network connection: Ethernet
  • Operating temperature: between 0°C and 40°C
  • Cooling: 12038 fans (2 pcs)
  • Dimensions: 350mm(L)x135mm(W)x158mm(H)
  • ASIC chip: BM1387
  • Rated voltage: 11.60~13.00V

Please note that for 12V DC input, 10 6-pin PCI-e connectors are required for an AntMiner S9.

And beginning from the shipping date, a 180-day warranty is available. More information about the warranty details along with price info and more reviews could be check out at

Antminer S7

For many people spending about $2,500 might be a little too high. So, the predecessor model to S9 which is S7 would be recommended in this case. 


  • Default frequency: 700M
  • Network connection: Ethernet
  • Operating temperature: between 0 °C and 40 °C
  • Cooling: one 12038 fan
  • Chip quantity: 135x BM1385 (per unit)
  • Rated voltage: 11.60~13.00V
  • Dimensions: 301mm(L)x123mm(W)x155mm(H)
  • Power consumption: 1293W±10%
  • Power efficiency: 0.25W/GH±10%
  • Hash rate: 4.73TH/s±5%
  • Weight: 7.5 lbs.
  • Hard Drive: 512MB
  • RAM: 512MB
  • Processor: 1GHz

Please note that, similar to S9, since there is no power supply included with the device, a unit such as Antminer APW3 should be bought separately to use with S7.

Similar to S7, there is also S5 and S3 models of Antminer with the main features such as 1155Gh/s @ 0.51W/Gh and 441Gh/s @ 0.77W/Gh relatively which could be checked out at (Antminer S5) and (Antminer S3).

AntMiner T9

This Bitcoin miner is another powerful server by Bitmain with key specs very similar to the top item in our list – Antminer S9. 

Also, the cost to get T9 differs only little with that of S9 model.

Here are some of the features of this miner:

  • Network connection: Ethernet (cable not coming with the product)
  • Operating temperature: 0C to 40C
  • Rated voltage: 11.60~13.00V
  • Chip quantity per unit: 171xBM1387
  • Noise level: loud (with a vacuum-like sound) – not for desk-top use
  • Power efficiency: 0.126J/GH (using Bitmain APW3 PSU)
  • Power consumption: 1450W(±10%)
  • Hash rate: 11.5TH/s(±7%)

And as with other models reviewed earlier, PSU or power supply unit for this server should be purchased separately since there is not one included with the this Bitcoin mining hardware.

Please see for more details and price information about Antminer T9.

S9 vs T9

As stated above in the features section of each hardware, while both T9 and S9 items cost almost the same – at least for the time being –, Antminer S9 is more powerful and more effiecent at the same time compared to Antminer T9.

So, we recommend strongly S9 between these two models.

As for S9 or T9 comparisons with other lower models such as S7 or S5, we should say that although S7 or lower models’ prices are much lower compared to these two top models but at the same time the given hash rate is very low as well.

Read on as we give more details on this in the next part.

S7 vs S5 vs S3

Hash rates and power consumption for these mining hardware are accessible above or on the web. The key thing when shopping for these relatively weaker mining tools is knowing whether one could make a profit using one of these items or not.

It’s not possible to say for sure the answer to above question due to different power prices in different parts of the world.

But using a useful online Bitcoin mining profit calculator such as users could enter different variables before buying any mining tool to see if their purchase is profitable or not.

So for lower models such as Antminer S5 or S3 we strongly recommend using the above tool to make sure enough Bitcoins could be mined with the server to cover power costs and provide some profit.

Along with these BTC miners, Bitmain has also made hardware for mining Litecoin such as Antminer L3+.
