All About BTC, LTC, ETH mining as well as other alternative crypto currencies
BitMain and their 55nm BM1380 SHA256 ASIC chip and the miners that the company has released based on it are quite popular and now the company has announced that they are ready with their new 28nm ASIC chip – the BM1382. As you can already guess the new chips will be offering higher performance at a lower power consumption, so you can get more powerful miners with the same size and power usage as the previous generation with the help of the new chips. The track record of the company is so far very good thanks to the fact that they are not using pre-orders, but ship from stock and announce products when they are ready for shipping, so you can get them fast at a good price and start hashing right away.
BM1382 has achieved 15.75 Gh/s in hash performance, consuming less than 9.33 W on chip level at 0.75V. This means 0.59 J/GH on chip. If the core voltage is at 0.63V, the efficiency will be 0.40 J/GH on chip. BM1382 will bring the power efficiency of Bitcoin mining industry to a new level which has not been massively achieved before. BM1382 represents a 20% power saving on its previous generation of 55nm chips and nearly 10 times of better physical densification, which will further improve the safety of the decentralized ecosystem.
BitMain BM1382 chip specifications:
– Process Node: 28nm
– Package Type: FCQFN-56
– Packaged Chip Size: 8mm x 8mm
– Number of Cores: 63
– Core Voltage: 0.75 V
– Core Frequency: 250 MHz
– Hash Rate: 15.75 GH/s
– Power Consumption: 0.59 J/GH (chip level, and it can be lower to 0.40J/GH by lowering the core voltage)
The first devices that we already expect to be available, probably by the end of this month, from BitMain based on the new BM1382 ASIC chips will be the AntMiner S3 miners. Devices, that will follow the design of the very popular AntMiner S1 blade miner. According to BitMain each S3 should be using 32 BM1382 chips and be able to provide a hashrate of 504 GHS with a power consumption of about 390W from the wall. So this is close to almost 3 times the hashrate of the old S1 with pretty much the same power consumption, not bad at all, but we also need to see this coupled with an attractive price. The new S3 miners have the potential to become a great option for smaller miners that want to be able to mine Bitcoin or other SHA-256 crypto currencies.
AntMner S3 Specifications:
– Effective Hash Rate: 504 GH/s±5%
– Power Consumption: 390 W on wall
– Power Supply: 4 +12V DC input, PCI-e connectors
– Power Efficiency: 0.77 J/GH on wall
– Size: 331 mm x 137 mm x 160 mm (Dual blades assembled inside a box, including the fans)
– Fans: Two 14038 fans mounted on both front and back ends.)
– Operating Temperature: 0 °C to 35 °C
– Complied with: FCC / CE
– Network Connection: Ethernet
We don’t know what the exact price will be, but considering that the company is able to offer 1 THS miner based on the 55nm older chips for a price of $1850 USD at the moment, the half of that hashrate and smaller and easier to produce new AntMiner S3 ASIC miners should be not more than lets say $750 USD, but that is actually a bit expensive. They need to be sold at a price of about 1 BTC or even less in order to become really more interesting for the users and to offer a foreseeable return of investment and some profit for the miners.
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.
The fresh information from CEX.io about the addition of an option to buy future mining contracts for Bitcoin has made us thing and calculate how profitable are they if we compare them to what other options are already available to start mining immediately. We are going to do a comparison between the FHA contracts (purchasing cloud mining hashrate for the end of April) that you can already purchase to the currently being shipped Bitmain AntMiner S1 BTC ASICs and to a BTC cloud mining service that is already available and running by offering 5 year Bitcoin mining contracts, namely the PB Mining Bitcoin cloud mining service. We are going to compare how much it will cost you to purchase 1 Terahash (1 THS or 1000 GHS) worth of Bitcoin mining hashrate at each of these services.
1 THS of ASIC mining hardware currently shipping:
– 5x 180 GHS Bitmain AntMiner S1 overclocked to 200 GHs each
– This will cost you about 5 BTC for the moment for the miners
– You will need power supplies for about 2100W for them
– You will need to pay for 2.1 KW of power an hour for electricity
– Miners will be at your door in a week and you will start mining
1 THS of PB Mining cloud hashrate currently being sold:
– The current cloud mining hasrate price is 0.0083 BTC per 1 GHS
– You will need to pay 8.3 BTC at the moment for 1000 GHS
– The cloud hashrate will start mining for you in a few hours
– No extra cost for electricity or need to support hardware
– This is a long term mining contract for 5 years that you purchase
1 THS of CEX future cloud hashrate for end of April (FHA):
– The current contract price for FHA is about 0.00799999 BTC per 1 GHS
– You will need to pay 7.999 BTC for a purchase of 1000 GHS contract
– The cloud hashrate will start mining in about month and a half for you
– No extra cost for electricity or need to support hardware
– You can sell or trade the cloud mining hashrate contract at anytime
So it seems that all of the above options do have their own advantages, but there are disadvantages as well. It is up to you to decide what seems the most reasonable for you at this moment if any of the options is a viable alternative for you. Based on our experience, the AntMiners are very good product and the company making them is really fast and ships from stock (if ordering directly from them), not to mention the always up to date prices going down with the difficulty increase. The PiggyBack Mining cloud mining service so far is working great based on our few weeks of experience using it, they also update prices after difficulty increase. The use of CEX.io for cloud mining is not so good of long term investment in mining hashrate due to the higher prices driver by the users trading on exchange, but if you use the platform for trade and treat the cloud mining as just an extra profit while trading it is not a bad option.
