14nm A4 Dominator ASIC, world best 1.5W/Mhs efficiency, coming soon


http://www.innosilicon.com.cn/uploadfile/2016/0330/news_20160330_05.jpg

Innosilicon, the world renowned creator of the dominating 28nm A2 Terminator, is proudly announcing the specification & availability of the exciting next generation 14nm ASIC code-named A4 Dominator. This is a full custom optimized LTC mining ASIC with a tremendous focus on efficiency and cost, providing an incredible up to 4Mhs per chip performance with as low as 1.5W/Mhs efficiency in a DCDC less daisy chain configuration. This will allow for next gen scrypt miners with an incredible 400MHs to 500MHs hash power per box, with easily over 300% better power efficiency over the previous generations and anyone else. The A4 miner will be the most profitable mining device in every category. Available as both an ASIC and a complete miner soon, nothing can touch the well-crafted A4 Dominator in terms of performance and cost in the next 2 years! Initial batch of A4 chips will be available in May for miner developer to design PCB and software. Mass produced A4 ASIC/Miners will be available in June/July 2016 based on pre-order sequence.


A4 Dominator ASIC & Miner Specifications:

A4 Miner: 400Mhs per 1KW power supply in one standard miner box
A4 ASIC: 3.5Mhs per chip performance at 2.5W/MHs nominal, see tables below on modes
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 8Pins/6+2Pins with 12V output
Included: Raspberry Pi running the most user friendly A2 terminator Software

Why are 2 of those links "mail to" links?

I have to say the dc-dc less converter plan is interesting, be interesting to see how much control over voltages and such there are in software, looks great I guess designing a PCB shouldn't be to hard now, only bad thing is looking at it we got more heat in a lot less space, the others were 12W with 144mm2 now we got 15W with 64mm2, anyway be nice if the ASIC alone don't cost an arm and a leg. Shouldn't be to hard to make a board to reuse the heatsinks at least and have nearly 70Mh/s a blade.

fixed the links sorry

 Your announcement is redundant, though 'till they post in this forum rather than the massively overloaded "announcements" forum that you can't find ANYTHING in, your post does serve a purpose.
 Says a lot that I found this thread 4 days before I found any link to their direct announcement thread (via an accidental find on a Google search, forums search here STILL can't find their direct announcement).



 As far as the no DC/DC converter part goes - that means the ONLY way to control voltage to the chips is to vary the input supply voltage, which basically means ZERO ability to control voltages in software. Same as the Antminer S5, which is part of the reason the SP20E was capable of MUCH better efficiency if set that way in software even though the basic efficiency of the chips used in each was about the same when those miner models were hashing at the same rate.

Yea I am not to happy with the dc/dc less control , I am sure it saves a bunch of money on boards which will cost the same if not more anyway I am not sure why they would integrate the power supply in the chip, it is already super small and the power density is going to be quite high for heat. while if it is a fixed ratio I guess is what your saying on the voltage then an external device could control them but it would be annoying. I am interested but don't want to pay a fortune for chips or boards and don't really like closed driver software either.

I don't think you understand the DC/DCless part.

It's JUST like any other string design, like the Antminer S5, from the sound of it.

 In theory, you COULD use a single buck and run a string from the buck to get voltage control on the string, but I dount anyone will impliment that sort of a setup.

Maybe true, I am guessing it is just a fixed ratio type of divider 12v in 0.6v out kind of thing put in 13v get 0.65v, yes I am sure no one will use an adjustable setup in production I was thinking more after market tinkering.
