Do not think. Look at the image .

Well, those individual heatsinks are on the backside of the chips, but, aside from the increased weight for shipping, I'd have prefered the S3 type top heatsink on the reverse side rather than those little things.

Well it is smart to put individual heatsinks on all the chips, I am surprised they didn't do that originally with the S5.

 Hair less than that at current difficulty, but close. That WILL drop over time of course. PS - that's per DAY not per HOUR, you'd be looking at ballpark $30/day income NOT $300ish per unit, at current difficulty and bitcoin price.


 I AM curious why this unit isn't designated as an "S6" rather than a S5 varient, as the form factor is a LOT closer to rack mount than single.

 My main issues with the unit are:
 (1) It should be a single size unit like the S5, not a "triple", as the flexability is nonexistant and the cost increment per unit is HIGH.
 (2) WAY too expensive, chance of being able to ROI this thing is pretty much ZERO unless your electric is VERY VERY cheap (UNDER 5c/KWH).
      It might be viable if it was under $2800 but even at that price WITH shipping it would be marginal.
 (3) CUSTOMS ISSUES at least for US customers, anything over $2500 gets a lot more paperwork needed AND a lot more scrutiny and probability of customs hassles
 (4) the efficiency isn't enough better than a S5 to make it worthwhile, especially at the major price increase over equivilent hashing power out of S5s
 (5) the thermal design seems VERY iffy given the increase in power density and the much higher airflow restrictiveness.

 If it was a 20 chip per string design, the efficiency WOULD be a lot better (still not equal to various claims about next-gen stuff I've seen, but at least competative with them), the probability to ROI would increase a lot IF the price was the same or lower, and the heat issues would be a lot less.


 Personally, I have ZERO interest in this unit as designed and priced. I'm still waiting for the S7 or the announced Lketc unit (Innosilicon A3 based most likely).

the 3400 watts its like 36 cents expensive per hour in consumption needs at least the 0.02 BTC per hours getting in mining yip seems nice the every TH gives you like 0.01 soo might even be 0.07 to just spend 0.02 its 250% profit a day like 1 BTC per day and spend only 40 dollars per day seems like a 160 dollars porfit per day till its pays the miner
let me see things right the all mining power its like 10 PH and to get a 10 mins 25BTC soo its 150 BTC per hour and 4000 BTC per day if you have 7,7TH you get like 4 BTC per day max and not the 1 BTC but you need a bit like to get the full 1000 dollars per day and pay the miner.
if the all net its just 10PH

However this brings the question; Does this mean we no longer get an announcement on the alleged s7 next month-ish?

I wouldn't mind that much, considering if this "was it", just mean what i have right now will stay effective for a bit longer. But i would like to see a newer small factor miner soon.

I hold thumbs for the S7.
This miner is out of the home miner hobbyist market with those power requirements.
 

Wow thank you for letting us know, that puts an end to the speculation

I think it will be after sept 30th

But my sources are not the most reliable

how about the s7?

Dear customers,

The S5+ is now opening for sale in Mainland China market(as some one has already found on the bitmain.cn), and it will be available for sale on global market next Friday. Then you can purchase the S5+ on our official website of bitmaintech.com.  


We recommend Bitmain customers to purchase our products on our official website, unless you have your own particular reasons to buy from other channel, for example, you known about the seller quite well, or you trust the seller, or the seller can provide very good support to you.

I think it would be nice if you give us a DB.  Sound reading. I would love to know if it is over 75 db

Yeah confirmed, was intended for the domestic market only though.

You can also try getting it from Bitmain's Chinese store: http://shop.bitmain.cn/goods.php?id=47

so can anyone confirm this is a legit product or not? is this the only website to buy this from?

I was offered one at a great discount to test from ITOP. I'm pretty excited to try this out. I will keep everyone updated.

wow were getting closer to my big in level.

Now look what all the talk about this monster has done to the price of BTC .....

It is on bitmaintech's China website.

Most likely this was a unit to be sold domestically as a smaller batch to finish off the chips, will see.
