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.
