We have been keeping track on the development of the new Innosilicon A4 Dominator Scrypt ASIC miners since the initial announcement back in November last year and it is time for another update. It seems that Innosilicon is starting to take pre-orders for the final ASIC miners with shipping expected to start in September and there is already a thread on Bitcointalk about a group pre-order that you might want to check out if interested. In the past we have tested the previous generation of Innosilicon A2 Scrypt ASIC miners in the form of the 86 MHS A2BOX Innosilicon A2 Scrypt ASIC Miner that was consuming about 1000 Watts of power, so we can see what the development is and how good actually the new generation is going to be. A solid first generation Scrypt ASIC miner that was built well and performed really good when it was released with the only drawback being the very high initial price of the device, so we were anticipating another good solid product with much better specs when the first A4 details surfaced.

The initial announcement from last year claimed that the A4 Dominator is so efficient that it should be able to deliver about 850 MHS for Scrypt mining with 1020W of power usage. This was really impressive number and really caught our attention, especially considering that the first generation A2 Terminator miners were able to achieve just about 1/10 of that hashrate with the same power usage. A little bit later, in March this year, there was an update on the power usage and efficiency of the new A4 ASIC chips that has significantly lowered the initial numbers – down to 400 MHS from 850 MHS per kilowatt of power. Although the expected performance was lowered more than half it was still a pretty impressive number, but unfortunately this was not the final change and now we have a new number available. Apparently the final product will only be capable of about 260 MHs per 1 KW of power and be available for about $1800 USD without shipping and with power supply not included in the price. While the final performance per KW of power usage is not that bad either, we are not as excited as we were with the initial announcement or the March update. At 260 MHS per 1000 Watts things aren’t that bad, but with these specs we are not going to be pre-ordering one of these miners for sure. Maybe we are going to try to get one unit to test when they come out if it is not a pain in the ass to secure a single unit order.

Last year there was some information about the upcoming next generation of Scrypt ASICs from Innosilicon as the company was looking for investors. Back then they already had apparently designed and taped-out the A4 Dominator chips and needed sufficient investment to start making the chips using 14nm production process. Now, about four and a half months later Innosilicon comes with an official announcement of the final specifications and additional details of the upcoming A4 Dominator Scrypt ASICs that are apparently now entering into production.

The next generation Innosilicon Scrypt miner using 14nm ASIC is code-named A4 Dominator as already expected. This is a full custom optimized LTC mining ASIC with a focus on efficiency and cost, that should be capable of delivering up to 4 MHS per chip with as low as 1.5W of power usage per MHS efficiency in a DCDC less daisy chain configuration. This should allow for next gen Scrypt miners to offer 400 MHS to 500 MHS hash power per box, with easily over 300% better power efficiency over the previous generations. Initial batch of A4 ASIC chips is expected to be available in May for miner developer to design PCB and software, mass produced A4 ASIC/Miners should be available in June/July 2016 based on pre-order sequence.

Innosilicon A4 Dominator ASIC and Miner Specifications:
– A4 Miner: 400 MHS per 1 KW power supply in one standard miner box
– A4 ASIC: 3.5 MHS per chip performance at 2.5 W/MHS nominal
– Extreme Low Power: ASIC with large memory running at single rail 0.6V
– One Start and New PCB: eliminate the need of DC-DC components and enable 14 to 20 A4 chips – running off the single 12V DC supply
– PSU Requirements: common PCI-E 8 Pins/6+2 Pins with 12V output
– Included: Raspberry Pi running the user friendly A2 Terminator software
– Server Grid Reliability: Built-in high-procession temperature sensor for automatic chip protection and variable frequency operation to maximize chip life time

There is no word about pricing at the moment, but it seems that Innosilicon is finally going to beat the KnC Titan Scrypt ASIC miners in terms of performance and power usage as the king in Scrypt mining efficiency at the moment. Unlike KnC however whose miners are no longer available and were problematic as hell and quite expensive when launched, based on our experience with previous A2 miners we know that we can expect a more affordable and reliable product from Innosilicon that should not give you a lot of headaches like many Titans did. There is no word on pricing yet, but a somewhat acceptable price would be in the 2K USD range, otherwise there might be not much demand for it with the current market conditions. With the high expectations we had and the total failure that SFARDS turned out to be in making available their products our hopes for Innosilicon finally starting to do something on the LTC and Scrypt crypto currency mining front are high, but let us see what will happen this summer…

The official announcement of the upcoming Innosilicon 14nm A4 Dominator Scyrpt ASICs…

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.
