bitmain-antminer-s9-asic

One more announcement fro Bitmain, the AntMiner S9 ASIC Bitcoin miner is no official and will start shipping on June 12th for $2100 USD without the shipping cost (power supply is not included). The device uses the company’s new 16nm ASIC chips BM1387 and essentially triples the hashrate of the previous generation S7 miners while offering the same level of power usage. The Bitmain AntMiner S9 should be capable of 14 THS SHA-256 mining hashrate with a power usage of 1375 Watts at the wall, so definitely a good improvement over the S7.

Bitmain AntMiner S9 Specifications:
– Hash Rate: 14.0 THS ±5%
– Power Consumption: 1375W + 7% (at the wall, with APW3 ,93% efficiency, 25C ambient temp)
– Power Efficiency: 0.098 J/GH + 7% (at the wall, with APW3 93% efficiency, 25°C ambient temp)
– Rated Voltage: 11.60~13.00V
– Chip quantity per unit: 189x BM1387
– Dimensions: 350mm(L)*135mm(W)*158mm(H)
– Cooling: 2x 12038 fan
– Operating Temperature: 0 °C to 40 °C
– Network Connection: Ethernet
– Default Frequency: 650 MHz

The big question however is if now was the right time to announce the new mining hardware, as of you order now from the first batch you might be getting your units delivered right before the Bitcoin block reward halving. So it might be wise to wait for a later batch of S9 miners after the halving to see how the situation will change and if you might get a better deal in terms of price for the hardware. Then again if you are using S7 miners you might already get to the planning for switching to S9 now that the previous generation S5 is no longer profitable barely covering the electricity costs.

bitmain-antminer-s7-ln

Bitmain has a new interesting offer for miners in the form of a lower hashrate ASIC miner for Bitcoin called AntMiner S7-LN that comes packaged with a 1KW Enermax ATX PSU. The new Bitmain AntMiner S7-LN apparently has less chips – 90x BM1385 instead of the 135 found in the regular S7 and as a result you get a bit more than half the hashrate at about half the power usage. The AntMiner S7-LN is rated at 2.7 THS hashrate and about 700W of power usage at the wall and can be yours for $291 USD without the shipping and taxes per unit – the miner and the PSU for it – with the shipping expected to start on June 2nd. The good thing about this offer is that the PSU is a regular ATX one so it can be used for a PC or a GPU mining rig and not only for ASIC miners when the time to shut down the S7-LN comes.

Bitmain AntMiner S7-LN Specifications:
– Hash Rate: 2.7 TH/s ±5%
– Power Consumption: 697W + 10% (at the wall, with Enermax, 25C ambient temp)
– Power Efficiency: 0.25 J/GH + 10% (at the wall, with Enermax, 25°C ambient temp)
– Rated Voltage: 11.60~13.00V
– Chip quantity per unit: 90x BM1385
– Dimensions: 306mm(L)*150mm(W)*275mm(H)
– Cooling: 2x 12038 fan
– Operating Temperature: 0 °C to 40 °C
– Network Connection: Ethernet
– Default Frequency: 700 MHz
– PSU: 1000W Enermax golden power supply

The only drawback is that the Bitcoin block reward halving is right around the corner, so in about a month and a half the coins mined by the miner will be cut in half. So now it might not be the best time to consider purchasing the current generation of Bitcoin ASIC miners even of the offer is an attractive one. So consider carefully whether now is the right time to purchase SHA256 ASIC mining hardware or better to wait for the halving and then consider what to do…

Innosilicon is apparently looking for investors into their new A4 Dominator Scrypt ASIC (both chips and miners based on them) to help them bringing the new the next generation 14nm chips on the market in a few months time with 1.2 Watt power usage per MHS. It seems that they have already designed and taped-out the A4 Dominator chips and are now entering the next round of full mask mass production using apparently Globalfoundries 14nm production process.

A4 Dominator ASIC & Miner Specifications:
– A4 ASIC: 3 MHS per chip at 3.6W nominal, support DCDC less PCB
– Extreme Low Power: daisy chained ASIC running at 0.7V, only in 14nm
– Miner Performance: 600 MHS from 720W at the Wall or 850 MHS from 1020W
– PSU Requirements: common PCI-E 8 Pins/6+2Pins with 12V output
– Included: Reprisal Pi running the most user friendly A2 terminator Software

“We have opened our A4 ASIC/Miner production to committed partners in order to share in both the cost and the profit. Anyone who commits $1.5 million to this partnership will get to share our ASIC production masks or purchase miners at cost for your mining farms. We have fully de-risked the design by shouldering all the R&D and MPW costs for the testchips. Also, we will showcase our testchip and test miners in couple of months to demonstrate the A4’s unsurpassable efficiency. We need only 4 to 5 partners to participate in this incredible risk free win-win partnership round.”

Apart from the new A4 chips that will be for Scrypt the company is also working on new A3 chips for SHA-256 that apparently offer less than 0.2 Watt per GHS, so things should be similar to their first generation A1 for BTC and A2 for LTC mining hardware. In our opinion however Innosilicon will have to work on something else as well and that is securing partners to make their mining hardware more easily accessible to users and not only to large mining operations. They could also work on an approach similar to that of Bitmain to offer direct sales to end users as apparently they could be the new driving force behind Scrypt mining with SFARDS going completely silent and other companies just now starting to look for partners to work on development and not production.
