Had the pleasure of seeing the prototype, its shiny


EDIT:

SUPER SECRET S2 PICTURE, NOW WITH EXTRA Tshirts

Very disappointed with the design, looks like those horrid other miners.

Expected a nice design :/

p
I wonder how low the clocks have to be dropped to reach the target voltage to stay at 1W/GH....
if its half the speed to meet 1W/GH, then each machine will have around 640 chips in it...
Which means S1 could be sold for half the price they are asking now. Based on chip density.
I wonder how easily the S2 will be oc'able ... knowing that its chips will be severely undervolted.

Ssshhhhhh!

If underclocked it is already pulling 1000W, you would need to add a PSU.   I do not see how they will run without
a 1200W PSU if they really draw 1000W.

Its only a prototype, most likely put together to hold it together in a very short amount of time.

I hope the finished product is that big silver box of hashing. .5 BTC of that price is probably for shipping and handling as that looks to be a big mama jama! We are getting to the days where Antminer S1s are the new USB Asic.

[San1ty]

Hmm...

1) Big Box
2) 1000W PSU for a 1000W Draw... Explosion in 3,2,1...
3) Pricy... 4BTC would have been a way better price
4) Still 55 nm chips

A bit disappointed. I wish bitmain stayed online to answer a couple of questions, especially on the PSU front.

[makngeerwork]

Agreed, shipped without a psu price would be nice, possibly in the future.

[Pcpoet]

Too pricey.

1) I'm fairly certain that box is larger than 4U.  I doubt it's the production case, however I could be wrong.

2) Interested to see the actual numbers.

3) 4BTC?  5 S1's cost ~4.96BTC, have less chips and no PSU.  This ain't a charity.

4) This is no surprise.  I'd guess the next model (S3?)  Will have a smaller process node.

I have an email from Bitmain a few weeks back saying till will be releasing a 28nm very soon with mass production mid april.

This box sent with a PSU will cause massive issues with customs and the custom fee will be $$$ or £££

Yes its good to have such good power in one box and easy to use but cmon bitmain using the same chip and just using more of them is not really more efficient when you have to take other things into factor.

You will be paying plus 7 BTC to get this thing imported.

also 4U looks more like 8U

These box designs are not nice but hey as long as its cheap and good and fast I don't mind but the price must be right.

These will never ROI even if BTC increases by 10%

[goggles1200]

We all need to remember that was a prototype. Would like to see what the final product would look like as of right now, it's a broken link on the page. Might as well have a picture of the Riddler up there. I do agree that the price and the power consumption doesn't make much sense compared to the S1. What magic is going on in that box for it only needing 1KW PSU?

It still has to be a valid purchase though, the S1's made that and returned ROI reasonably quickly @6BTC ROI will be 9-10 months away.

3) Ok, I might have been a bit aggressive with my price point.

Anyway, with the hashrate that's getting deployed this year, you better ROI fast with these because in a couple of months they won't pay your elec bill anymore.

Slush's pool just added 220TH here the last couple of days and dropped my return per block down by 20%. With more power being added, 9-10 months away is generous and in scheme of things is way too long.

I'm not saying that I like or dislike the S2 pricing, just that 4BTC didn't make sense as a talking point.

Which should balance out with an increase in blocks being solved per 24 hours.

Sure, a lot of hash is in the works, but a lot of hash is always in the works.  It's all relative.  Each of us is going to have to make our own predictions and crunch numbers.  These are going to be a lot more attractive to people with cheap power who have reached their electrical load capacity vs. those with higher rates and/or have not reached their current capacity. One thing is for certain though, I like having the shipping from stock options vs the pre-order model.  Hell, it looks like these units are a better deal than going the Cointerra route.

I'm not going to lie, this feels like a punch in gut.  Disappointed in Bitmain.  It would be something if it's new technology, but it's the same 55nm chips they use in the S1.  Didn't they sell over 33k Antminer S1s so far???  Their quote:

S1 is currently deployed in large binary trees structures within the private and public mining pools servicing 20.3% of the entire network hash rate.

They made a killing already, why not treat their loyal customers with respect?  Slap the same old chips but more of them in an ugly 4U case.  Very frustrating news, to say the least....

Just wait till be hit 12.5 BTC per block.... then it its time to greet

What does it matter?  The only competitor that beats it is Bitfury and they're super pricey.  I guess you could throw the Chinese Coincraft A1 miners in the mix, (maybe) slightly better efficiency but they want $6,000+     You could take the risk of buying an Avalon Gen3 for slightly more than the S2 as well.

As a customer of Bitmain, I don't feel that they owe me respect, I feel like they've already given it to me by a) being a standup business; b) adjusting their price daily to give us a chance at +ROI; and c) producing the S2.

If you don't like how they run their business, feel free to pre-order from HF, Cointerra, BFL, Bitmine, AMT, VMC, take the risk of buying from Avalon, or pay through the nose for Chinese A1 units and/or Bitfury.

If you're stuck on 55nm just sell the S1 underclocked and let people build up their 1GH/W hashing power from smaller cheaper units.
