Topic: Announcement: Bitmain launches AntMiner solution, 0.68 J/GH on chip - page 160. (Read 368321 times)

How is this the most efficient? Pretty certain BitFury was demonstrating very low J/GH/s values with very low voltages. Just not practical to run the chips that low given how cheap power is compared to the silicon cost.

Will be interesting to see the $/GH/s and the density. More competition is better.

Great work.


Yep 

Yay, this company looks legit! This would be the most efficient ASIC chip on the market, no?

chip 8x8mm?

this one for sure: http://i.imgur.com/5B3WMnQ.jpg

but this one?: http://i.imgur.com/9jNUKvb.jpg

This are not the same chips if I see it correctly!

very interested, will have to keep an eye on this, please let us know when US distribution is available.

Congrats on this result! Can't wait for the next update

That's very good news. Now waiting for the right price. Will you sell individual chips or just assembled miners?

That looks like great!!! No fan thats a first at those speeds. Does it have ethernet connector built in?

Nice ! Keep up the good work.

An quick update

In the afternoon of 12nd Nov, After testing the single chip for over 24 hours and the speed in pool are all right, we decided that the chip can work stably alone. We tried lots of voltage-frequency-efficiency combination. Here are some of them:

	Vlotage(V)		Hash Rate(GH/s)		Total power(W)		J/GH
	0.75		1.60		1.07		0.68
	0.85		2.00		1.69		0.85
	1.00		2.50		2.82		1.13
	1.10		2.80		3.70		1.32

From the afternoon of 12nd Nov, we started to test the multiple chain mode of the chip. We worked on it through the night. We slept only 3 hours in the early morning, and got up work again. In this afternoon, we decide that the multiple chain mode works all right.

Below is the photo of the testing board we soldered and assembled. It runs at 1.6GH/s per chip (50GH/s per board), and it does not need fans to be cool ( 60℃ without fans) . However, we will still prefer fans added when it is mining, as the low temperature will help the DC/DC efficiency a lot. We will test the 2.8GH/s per chip(90GH/s per board) tomorrow. A young hardworking engineer is soldering it right now when I post When the chip is running at this speed, efficiency will be 1.32J/GH, but I guess the heat sank we ordered will handle the heat, with very low speed wind. The ambient is 27℃.







 

Philipaman195, thank you very much for you input.

 If it works at under 2 watts a gh at the wall.
If the price is correct .
If the gear ships fast I want some.

Usb sticks   will  sell like mad on USA ebay for the right price.   a .333gh am stick  is selling at 15 usd or more on ebay as I type.
 it these are easy to setup  and can be sold for 60 usd on ebay people will buy them.    If they sell at 90 usd on ebay people will buy the red fury stick for 115 usd.

There have been more then 300,000 am sticks sold on usa ebay.    if these sticks hash at 1.6gh people will want to upgrade.
Ebay is all about price points.  As a seller of  sticks selling this for 60 usd a stick means I need to pay 40 usd a stick. If I sell single sticks.
 If I sell sets of 2 sticks for 120 usd.

  my  cost  could be 45 a stick.  2x 45 = 90 my fees are 9 usd 99 and shipping is 6 usd .   105 for my cost 120 for the sale means I make 15 bucks a sale .     

 I am basing this on 350 usd a BTC.    So if the sticks come out at 50 usd a stick or more  It will be tough to make a profit selling them.
My interest is on the sticks as I know there are 10's of thousands of people running AM sticks. I sold a few thousand sticks on ebay.
I was hoping for red fury sticks to be the new replacement stick but  they are harder to setup. They cost too much and supply is small.  I am hoping you can produce a stick that works well with the correct price.

Same here.

Very interesting - if the price will be reasonable!

Very interesting.

Do you plan to do bulk chip sales, and if so when do you plan to release a datasheet documenting the specs and interface with the chip?

Thanks

VOLUNTEER

I can be in Beijing or other office in a few days, if you guys let me come visit!!!  (I'm being Serious)

Take a group photos and write about the update as of that day

I can arrive at your office this weekend or early next week at latest.  What do you think?

This is an INTERESTING MINER UNIT & CONCEPT for sure

11/18/2013 is a BIG Day for the Bitcoins in USA.  Should be able to get to China before then!!

huh.

seems pretty interesting.

cool!!! i'm look forward... what's the time ready for sale?

What is the J/GH and V at 1.5GH/s? Waiting for more pics. Maybe with 2.8GH/s.

Now the software is working properly with the pool, but the speed reads in our cgminer fork is still biased from real speed. The error rate looks high, but it is because we frequently drop and restart the power of the chip, When we run it continuously, there is very little error.

The chip is quite adaptive with different voltage and frequency combination. There are still lots of testing job need to do, but we prefer to let the chip run at 1.1V-2.8GH/s-1.3J/GH for the first batch of S1, if nothing goes wrong.
