Antminer ( S9j Vs S9-Hydro )

in #crypto6 years ago

Hello friends I hope you are very well, a couple of months ago I made a post about how to buy a T9 antiminer, today I am going to share a small comparative analysis between two bitmain teams, the technology advances quickly and companies try to find ways to optimize the resources and the power of the equipment, currently the most powerful bitmain equipment is the S9-Hydro, can be seen as an improvement of the S9, (the S9 has several versions and its power varies from 13TH / S to 14.5TH / S ) the current price of these equipment is about $ 480 (with source) but with the cost of shipments from China plus import duties may end up costing about $ 900, the S9-Hydro has a much higher cost, is currently at $ 745 ( without source) and has a mining power of 18TH / S, if we include the source plus shipping and import costs,the team ends up costing about $ 1500.

Cost benefit analysis

As you can see the difference between these two equipments is 600 $, the cost per TH of the S9j-14.5TH / s is 900 $ / 14.5 = 62 $ / TH, on the other hand the cost of TH of the S9-Hydro is 1500 $ / 18TH = 83.3 $ As we can see the cost of the TH in the S9-Hydro is 21 $ more with respect to the S9j-14.5TH / s, if we analyze the electrical part (current consumption) the S9-Hydro has a higher consumption that the S9j-14.5TH / s (10% more), in countries where the electric cost is high, this can be considerable at the moment of paying the electric bill, and would diminish the benefits that the equipment leaves.

Sound and temperature

The BTC mining equipment is quite noisy product because they have Fan Coolers of a large number of revolutions to be able to circulate fresh air inside the equipment and maintain an adequate working temperature, one of the disadvantages of this equipment is that it does not they can be in a closed place since when expelling hot air of constant form, the atmosphere raises of temperature quickly and begins to enter hot air to the equipment increasing the internal temperature (the high temperatures can damage the equipment), apart when going increased the temperature from the environment the Fan Coolers begin to increase their revolutions trying to lower the temperature of the equipment causing even more noise, the S9-Hydro was developed with a water cooling equipment,this brings good enough benefits for the reduction of the sound and it expands the possibility of places where the miner can be had, since it is not necessary that it is a wide place and with constant flow of air, this point unquestionably wins the S9-Hydro.

conclusion

The cooling by water that brings us S9-Hydro is an important factor for entrepreneurs who do not have large hangars to place their equipment to mine without disturbing the sound to the neighbors, but pay $ 21 more for TH than a S9j-14.5TH / s I do not think it's worth it, all people want to recover their investment as fast as possible and the S9-Hydro is currently the mining team that gives you a longer return on investment, so evaluating the benefits and disadvantages of each One the S9j-14.5TH / s is the undisputed winner.
