the S3 is already getting outdated with only 453 GH/s at the price of 0.58 BTC without PSU

Any news on the upcoming Antminer S4 ?

We do need a solid unit producing more than 2 TH/S +,  maybe at the price of 1,5 BTC or lower

they should come out with their S2 upgrade before they announce an S4.  maybe they will announce in conjunction.  if you assume the same ratio increase as the S1 -> S3, then the upgraded S2 "should" be somewhere in the area of 2.4+TH, and i think with some room for overclocking.

I was hoping something like 5-10 TH/s and really compact. Waiting patiently..

Are they switching to 20nm for S4? Any info when we can expect it at all?

I highly doubt it.  Chances are they're going to follow the same paradigm with the S4 as they did with the S2: lots of underclocked chips.  So, they'll continue to use the BM1382 that's in the S3.  Quite honestly, I'd expect the S4 to look pretty much exactly like the S2, with some minor improvements like better bracing of the hashing boards on the backplane, etc.  My expectation is somewhere around 2.2TH/s at 1300W will be the specs on the unit.

Batch 8 of the S3 and the S1 upgrade kit do not even resume shipping until September 20th.  so I would not expect to see another device from them anytime soon.

i need more info, it may turn to be profitable for the first few months, diff might stay there if the price is decreasing

Well whats the point of making new ones at the same W/GH ratio? We can just order bunches S3s.

It's a better W/GH ratio... S3 is 0.77W/GH, my expectation above is about 0.59W/GH.  I don't think they're going to see the kind of improvement they saw on the S1/S2 simply because the BM1382 chip is already achieving a respectable power to hash ratio.  Hopefully I'm wrong and they manage less than 0.5W/GH... but I doubt it.

You will be pretty shocked, they might be testing new chip for a s4 right now. 

there is not much money in s4. even at 1300 w/2.2th it has to be just $1500-1600 to be a leader/competitive in the next mo or two.

well you can order this 1.4th -1.7th  dragon using 1070 watts   for 1290 usd sans psu

 it will ship on the 2nd of sept.  may be best deal around


if you buy 2 it is 1265 each

if you buy 3 it is 1240 each

I believe that Antminer S4 will come out in October. Just a hunch

   a long way out. 35 plus days

Agree, after 35 days the difficulty would increase at least 50%.

S3 is to S1 as S4 is to S2 would be my guess.  They can create the S4 and still "milk their product".

The S2 looked like it was made to help clear remaining stocks of the old chip before introduction of BM1382 based machines.
I don't expect to see an S4 until Bitmain are ready to clear out old stocks of the BM1382 in preparation for the successor to the S3. My guess is this will happen in 2015 given the current success of S3 orders.

I hope so!  Although I'm not very confident that I'd upgrade my S2s even if they do release something. My S2s have still not hit ROI and I don't like to throw good money after bad.

They're at 67%, would be closer to 80% but had some shit luck at BTCGuild for a good stretch when I first set them up.

Should be in the black within the next two to three months.  :-\

I guess since they fitted 10 cards inside a S2 they will now take the 10 cards in the S4 making it a monster of 4.5Th/s
clear speculation off-course!!!

If the S4 follows the pattern of the S2, it certainly won't be 4.5TH/s.  Remember, the S2 underclocked/undervolted the BM1380 chips from the S1 to make that 1TH/s at 1100W - typical ratio of the chip was 2W/GH/s.  If they hadn't, the S2 would have been a 1.8TH/s miner consuming 3600W.

The speculation is that the S4 will indeed follow the same paradigm established by the S2.  My thoughts on the specs are earlier in this thread, but to reiterate them here, I believe it will be around 2.2TH/s at about 1300W.  If Bitmain wants to use the same PSU as the S2, then it'll probably be closer to 2TH/s at 1100W.

they would improve the PSU, ofc.

Good luck hooking up three 1200w PSUs to that! Lol.

This reminds me of the poor souls who used moron-math and thought KNC was going to ship them 15THs Neptunes instead of 3THs.

S4 might end up being some rack mounted creature to compete with SP31s.  It may not be usable in households (at least not US 110V).

I actually prefer SP31 because of the compact setup.

Sp-31 maybe expensive but its good looking

interesting to see

SP-31               3920 uSD / 5500 ghs = 0,7127
S3     0,58btc      300 USD /   450 gh  = 0,66 (if its 500Gh then 0,60)

off-course needed PSU for the S3 and its more quiet for household use.
I dont mind the noise as I host them in my warehouse

now if S4 goes for 2000 ghs we must wait to see the price
 

Was hopping S4 is at least 5 Th and is cheaper then SP-31 in-term of price/ghs

Bitmain as we have noticed is afraid the transport of bigger boxes from China.
They prefer small antminer boxes like s1-s3 when they have problems with S2.
Remember the horror pictures we saw early 2014 with the S2 miners
So making a big big miner boxes is a problem

What problem did they face transporting big box?

For some people, hashing boards became disconnected during transport and were tossed around inside of the miner. They eventually improved the design and it became much less common. I'm sure they've learned their lesson.

But for most people, all they had to do was open the case and push down on the boards to reseat them.

any news on the S4 ? i've heard they are already testing it !

Hashrate means nothing if you dont even have ROI.

Dont come back here and cry because you're super doper 100TH/s is a lost investment.

That's because they were idiots and didn't attach the boards to anything. Take a look at any PC. There is a bracket at the back of each card that screws into the case. Missing from the S2 (mis)design.

dude,really ?

I have herd that S4 will be released later on this week.

heard where?

Really? where did you get that info.

OMG, the S4 has been released TODAY! This is insane!

Just think about it before getting fooled by a joke!  ;D

come on bitmain, give us some news !

They just came out with an S1 upgrade, so I don't think a S4 will come out soon.

nobody is buying the s3 anymore.
i think it would be a good ideea to come out with an s4

You must have overlooked that an update on the S4 test results was announced by @BITMAIN already due last Tuesday.

With the SP20 now around the corner, Bitmaintech does not have much time left to come up with something that is at least on par with the specs (means whatever they can tickle out of the 28nm tech to optimize hashing power vs. energy consumption).

were did you read this...
I think they spent much time building the hashnest and this is why S3 production delayed for a month
they dont have time I guess

Here (https://bitcointalk.org/index.php?topic=330665.msg8598489#msg8598489) you go.

still no news... they are getting chewed by spondoolies

The S3s are still selling like hotcakes. They'd only cannibalize sales of the S3 if they introduced the S4 now. They know what they are doing. They're maximizing profits. And no, Spondoolies is not "chewing" them. They're probably still outselling them 10-1.

Still waiting for s4.. any sneak peak?

I think they just had Moon festival last week.  They are celebrating Sun festival right now.

sothis should be next top-seller, right ?

Waiting for this really long, hopefully its 100th

100TH/s?  You might want to rethink that one... not a chance in hell of that happening.

When's the Festival of the Dung Pile?

Ask and ye shall receive!   ;D

2 TH/s shipping before the end of September, get 'em while they're hot!   :P

Holy crap! Now if they only get $/GH and W/GH right!  :o

I ordered yesterday 2 s3+ s  costing 1.16 BTC.
If the price of S4 which is 2TH/s is 1.16 or lower it's ........beeeep.
I think bitmain will make S4 ships single not like S3 shipping double.
And I guess the price of S4 will be 1.38 btc
Anyway I may also order s4 depending on the price.

Quoting myself ... looks like I was spot on.

so is it out, or any specs known ?

Quoting myself too...for being 180 out like a distributor in an old chevy!

I hope the price is lower we were going to buy a mass load of s3's but if its lower then spoonies hardware then we may be talking about something interesting and i wouldn't mind it being without a psu I can rig the psu myself if it means cheaper prices.

Nope, the only info is 2TH

Good luck if you think you're going to be paying 1.38btc for an antminer s4  ;D

If the price is 1.38 or more then it better come with a psu unit for that price and the full 2th once you over clock it.

$1450 for the S4: https://www.bitmaintech.com/productDetail.htm?pid=00020140916100720380cS1tRWd00684

This is definitely a non-starter.

"Oh, if Bitmain prices the S4 at 30 cents each, I'll buy 10!"

Once again the pie-in-the-sky optimists are shot down in flames, lol.

Close!  Just 2 BTC's short.... :'(

Well, that determines that the S4 is for the rich bitcoinists, and all the rest, who can count will buy the batch10 Antminer S3, because with that you can have 2 ths with only 2,32 BTC!

sp30 starting to look real good now. sad to say. < bitmaintech fan and owner

Except they haven't been selling SP30s for quite some time now. Your only options are SP20 delivering the 2nd half of October or SP35 shipping late November.

There are really no good hardware options to buy at the moment close to ROI.

This is the only half way decent one right now, at a reasonable price:

https://bitcointalk.org/index.php?topic=795477.0

Oh, and unlike every other Bitmain offering to date, shipping is NOT included in the $1450 price.

EDIT:

So, now that it's officially on sale, all I can say is, "are you freaking kidding?"

$1450 (currently 3.514BTC), shipping not included.  Shipped to Umisoo cost is 0.103BTC.  Shipped to my home cost is 0.39BTC.
2TH/s at 1380W (0.69W/GH/s).

You've got a better chance of stepping in a pile of fresh dinosaur shit while being struck by lightning than you do of making your investment back with this thing.
