The company Bitmain Technologies has announced that the production of the successor of their 180 GHs AntMiner S1 Bitcoin ASIC (on the photo above) is underway and they are going to be shipping the 1 Terahash AntMiner S2 starting in April (next month). The Bitmain has become known for their fast shipping and very competitive prices that go down with the difficulty increase and they are yet again showing how to do business with BTC ASICs. The new S2 units are based on the company’s 55nm BM1380 chips that are used in the S1 miners, but apparently they have managed to achieve high-density chip chains and lower power usage in order to be able to squeeze 1 Terahash in a 4U case along with a 1000W PSU manufactured by Enermax.

Bitmain AntMiner S2 Specifications:

– Hash rate: more than 1,000GH/s
– Power consumption: 1,000W from the wall
– Power efficiency: 1Watt/GH/s
– PSU: 1000W produced by Enermax, 80PLUS gold
– 4U Rack
– PSU inside
– Plug and Mining
– Stable and quietly

The pre-orders for the first batch of the new Bitmain AntMiner S2 1 THS ASIC miners have been filled with a price of $3899 USD (6.34 BTC) and a shipping date of April 1st (not a joke hopefully), the second bach of devices is scheduled for April 10th shipping and the price is a bit low at $3599 USD (5.852 BTC) and there are still units available. The new S2 miners do come a bit more expensive than 5x AntMiner S1 miners overclocked to 200 GHs each to give you a total of 1000 GHS with a price of less than 5 BTC. The difference however is that the power consumption for the S2 miner is 1000W and for the same hashrate with S1 miners you would get roughly about 2100-2100W. So with S1 you get cheaper price for the hardware (you will need to also buy 5x 500W+ PSUs for the miners), but more than double the power consumption for the same hashrate, even though the same chips are used in both products. Putting more BM1380 chips running at lower voltage and frequency is what BitMain has done in order to lower the power usage and get better performance per watt without having to increase the cost of the hardware too much.

Bitmaintech, the company making 180 GHS AntMiner S1 BTC ASIC devices is still pretty much the only company that only sells units that are on stock and are shipped fast to you with express delivery. Currently the price of a single 180 GHS AntMiner S1 is 1.345 BTC directly from the maker and that includes the shipping costs too. But the question that arises is if these devices are worth investing in now with Terahash ASICs right around the corner? That is why we have decided to do a comparison between the 180 GHS AntMiner S1 ASIC and a cloud mining service as an alternative option and we have chosen the PB Mining Bitcoin cloud mining service. We choose that provides of cloud-based hashrate for mining BTC as they currently offer the most attractive price per GHS of just 0.0089 BTC per GHS.


We choose the PB Mining service for comparison as we have been using the service for a while already and it seems to be running smooth and without issues. Note that what you get there is a mining contract for 5 years, there is no exchange available where you can trade the purchased GHS. This long term contract is the reason why the price is much more attractive as when compared to or other similar services.

So what are the raw numbers:
– 180 GHS AntMiner S1 is 1.345 BTC
– 180 GHS Cloud Mining is 1.602 BTC

This you should however add some more to the price of the AntMiner S1 as you will need to buy a power supply for using the ASIC as there is none included. For a good 500W power supply that you will need you should add in about 0.1 BTC more, plus customs taxes for the ASIC as it is shipped from China that are going to be at least another 0.1 BTC and you get 1.545 BTC or a value that is already pretty close… With the current value in two-three days mining you will be able to cover the remaining difference and you may need to wait for about a week for your miner to arrive, and the cloud mining hashrate will start mining for you pretty much right away or in a few hours after you send the payment.

So it seems that the PB Mining cloud mining service seems an option that is not less attractive than purchasing an 180 GHS AntMiner S1 ASIC device. Of course there are other variables as well, like the fact that you can easily overclock the AntMiner S1 to about 200 GHS, but you will also have an extra cost for the power used by the device that will probably be covered by the extra hashrate achieved by overclocking the miner. So you really have an interesting cloud mining alternative than to purchase mining hardware, both will take pretty much the same time for you to break even before starting to make extra Bitcoins. The choice is yours, but you should consider the alternative options you have in the form of cloud mining instead of purchasing ASIC hardware directly from the manufacturer even if it will be shipped immediately to you.
