Bitmain Antminer S4 !

[vortexz]

the S3 is already getting outdated with only 453 GH/s at the price of 0.58 BTC without PSU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

[dropt]

They're going to milk their product until its time for the next generation of miners and october is pretty soon for another iteration of Antminer.

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

[s1gs3gv]

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.

[dropt]

You're totally right if they stick to this and make it a pattern this very well could happen.

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.

[dropt]

How close are they to roi?

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. 

[lowbander80]

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!!!
