AntMiner S4 2TH/s for sales shipping before September 29th

Only Available at bitmaintech.com

Published on September 1st, 2014,

The enormously powerful and power efficient AntMiner S4 2TH/s is now available for sale globally.
The 1st Batch of AntMiner S4 is 1,450 USD per unit (excluding shipping), with dispatch estimated September 29th. Batch 1 will go on sale at 22:00pm Sept. 25th Beijing (UTC +8 Time Zone)

The AntMiner S4 is the fourth generation Bitcoin mining rig by Bitmain. It uses the state of the art BM1382 chip powered by the 28nm tech process with ultra-low power consumption.

Power efficiency progress is reflected from the S1 to the S4 and is our focus to improve your investment and save on electricity bills.


The AntMiner S4 is built into 3U size box, although its hashrate is twice that of the S2. The S4’s design is hugely improved from S2’s experiences, using less hash blades and adjusting the space structure in each box to bring a light and portable model. It will be very convenient to deploy.


Specifications:
* Chip Operating Voltage: 0.72V
* Chip Quantity per unit: 160
* Hash Rate: 2,000GH/s guaranteed
* Power Efficiency: 0.69Watt/GH/s at the wall
* Over clocking: About 10%, but not guaranteed
* 3U Rack  432mm*442mm*133mm
* PSU inside: 1400W, 80PLUS gold. Power line not included. You may look for one line with no less than 16A in your local market
* Temperature: 40-50 degree Celsius tested in the mining farm
* Fan Speed: 3900RPM
* Stable but a little bit noisy
* Ethernet connection, Stand alone
* Certificate Compliance: FCC/CE


Notification for S2 Upgrade Kit - Coupons being issued

To all customers that ordered AntMiner S2s: We analysed the business case for S2 upgrade kits for end users and determined that it would not be worthwhile for either party.
* The S4 runs at 0.69 W/Gh/s power efficiency, which is significantly improved compared with the S2’s 1W/Gh/s. Even though the upgrade kits used the newest BM1382 chips manufactured at 28nm process, it was not a significant leap in power efficiency.
However, the next generation chip is more likely to be worth doing upgrade kits with.
* The S2 is still profitable to run for the next several months with its 1W/Gh/s power efficiency and so now is not a good time to replace them.

Coupons will be issued to express our sincere thank you for supporting Bitmain over the year. Each coupon has a value of $200 and will be issued for each S2 unit purchased. These coupons are only applicable for the purchase of S4s and only one coupon can be used per S4.
If you ordered an S2 on bitmaintech.com, please check the coupons automatically added to your account. If you ordered an S2 from our authorized partners, please contact them directly to get your coupons. Below is the list of the authorized partners:

[CryptoCrane]

Hooray!

[dimaze]

Mmm.

[vortexz]

price ?
why so few details ?

[suchmoon]

Such tease. Well at least it's not another preorder, just about a week or so before shipping.

[area3121]

are this miner have already PSU inside?? or without??


im thinking it is a YES?? its already have psu inside?

[whonesta]

If price is > $0.60 USD per GH...   Meh!

[area3121]

If price is > $0.60 USD per GH...   Meh!

what ever the price... antminer s4 will be sold out @least a day after it will release ^^ 

[vortexz]

tell us the release date and price so we can have time for preparation !
we need to know how many bitcoins to buy

[whonesta]

LOL I guess there is a moron born every minute. $$ means everything and not a single manufacturer has sold out of shit lately, thus why they are ALL offering cloud hash. Ugh surrounded by idiots and water... 

[iglasses]

This is BS...after the S3 fiasco Bitmain should not get a single BTC for an S4 until the device is proven & available.

Stop the cycle guys.

[ThePhwner]

How about some reasonably priced upgrade blades to retrofit all these S2s sitting all over the place?

Likely or a bit more. Sounds like and looks like it has a PSU built in. Weight is a factor for shipping. One reason why the S3 is so cheap is they save a lot on shipping costs due to lighter weight/no PSU. Keep in mind these ship from China.

Considering you can get 2 TH roughly with 4 S3+ units (2.32BTC) plus .60BTC for separately bought PSUs, unless it's drastically more efficient power wise anything over 2.95 BTC and the S3+ is a better deal ROI wise.

Just my thoughts. But looks interesting. Maybe they will surprise us.

I hope it's less than 1.7 BTC

[MrTeal]

I hope it's less than 1.7 BTC

You want 2TH/s ready to plug in and go for less than $800 shipped?

Good luck with that.

[suchmoon]

unless it's drastically more efficient power wise

If it follows the same pattern as S1/S2, S4 will be significantly more efficient and significantly more expensive than S3.

Strato

they wont give u the best PSU inside these device  
just like S2, enermax 1000W ==a
They're choking the PSU  hahaha

lets assume...

- i can buy a better PSU (in terms of efficiency, reliable, and trusted)
run it for 1or 2years  , then sold it via local or Ebay with a good Price (prefer local)
and ofc its easy to sell PSU, just cut 10-20% of the new price (coz its 2nd hand)
so, maybe we dont need to calculate the PSU while we can get back about 80-90% money spent on it

- i buy 5 units of S3+ (BTC2.9) , run it without OC, i get 2250 Gh/s (we play long term and no AC, no money for it  )

- S4... u'll get 2PSU inside for sure, they wont place something like 1500w Platinum for sure again.. or... maybe they'll place server PSU
i dont trust these server PSUs. noisy, no warranty (even if Bitmain give u the warranty, its not worth it, heavy + wasting money on shipping back to China)
better get something that you can claim locally

- even if Bitmain give u 2units of 700 / 750 / 800 / 850 W PSU, can you claim it locally?
       

hope you guys can compare it better than me, save ur money for the better things.. haha

Of course it will. It would be a joke otherwise. Significantly more expensive than the S3 makes alot of sense....you are looking at something that has the performance of nearly 4-5 S3s. Collectivly speaking tho it should be a bargin against getting S3s IMO. But not so much of a bargain that they screw up their own sales margins on the S3.

I personally like the S3s for their lower power footprint. I imagine I am not the only one. The rack mount form factor is nice as well for nice neat stacking. And it looks like a smaller footprint if the picture is accurate.
