I think "one Neptune" will be these 5 Boxes and a controller board/box.
Wikipedia say one 6 PIN PCI-E can handle 75W - 8 PIN 150W. And they want to deliver 450W through one 6 PIN?
As a refund customer i'll grab some popcorn and watch these things catch fire

A Mini Neptune will be 3 boxes and soon there will be solo boxes with ~500GH for ~$1000?
Compared to a RK-BOX ~440GH/S with 480W (they use 4*6PIN PCI-E) for $650 its a bad choice

Manufacturer's rating on the Molex Mini-fit JR is 8A per pin.  That's 24A and these units are listed to draw 35A per plug.

I won't be surprised if they start melting.

FIVE boxes? *slow descent into the dark ages pending*

on the plus side - you will be able to heat every room in your house (with enough PSU's)

[jelin1984]

Yes the hashing speed is too lowwwwwww

[rograz]

Also thats At-The-Wall numbers, take into account 80% efficiency PSU's and thats easily 0.56W chip level consumption. Not too bad really.

Yeah, a 20nm chip that's about as efficient as Spondoolie's 40nm chip. Spondoolie's 28nm chip will slaughter KnC.

Yes let's compare a company that tunes their offerings for efficiency with one that tunes their for performance, you have no idea what the KNC chip is capable of until you undervolt one yourself or get some data out of KNC.

20nm  @  ~0.7W/GH    

Talk about a fail.

All it means is that those chips are clocked more towards their frequency ceiling than for efficiency, so for KNC it's a success since they get to send as few chips as possible to fulfill each order. They could easily have delivered sub 0,5W/GH but it would have cost them more to do so, so why would they?

Also thats At-The-Wall numbers, take into account 80% efficiency PSU's and thats easily 0.56W chip level consumption. Not too bad really.

Compare that to AM's 40nm, or Bitfury's Gen2 55nm.

Fun with numbers

3T divided by 5 ASIC = 600GH/s per chip

600G divided by 1440 core = 416 MHz per core

run same cores @ 500MHz for 3.6T
(my best guess for initial target speed)


YMMV

How many PCI cables needed?
This is more or less 200Amp, or 10-12 pci 6 pin connectors?

2100W under a single fan?
Can those heat amounts be dissipated through that small construction?

Also, how is the heat being dissipated from the chip?

Water cooling? Or ? ? ?
 

I'd guess that 5 of those boxes makes a full neptune, so 3000/5=600GH per box. 600*0.7W/GH = 450W per box.

LOL really ?!! 5 machines = 1 Neptune , jeez why could they not have just split it into two 1.5TH boxes instead of 6x600

no, not really. It's a single box.
BTW... Titan shouldn't be far behind this....

quoted for future lolz

it certainly bamboozled me when I got an email telling me it was 5 boxes.

[s1gs3gv]

So batch1 and batch2 customers will get another Neptune (free) in early August it sounds like.
And meanwhile, 3TH @ 15% difficulty increase should get you about 4 1/4 BTC between now and the beginning of August.

Which implies that unless BTC/fiat increases a lot between now and then that $5000 SP30 pre-orders shipped by the 1st of August will be on par or ahead of the ROI game.

Unless KNC bump the Neptune via firmware improvements. Does KNC have a history of doing that on products ?

you did?    I'd be "bamboozled too, lol  that would mean 1 pcb, 1 asic, 1 controller, and one BBB for every box unless they totally re-designed the pcb to include all...?  Sure seems like the expensive way to go unless this is an RMA planned event....

+1

Talk about fail. KNC have no advantage from 20nm. It is the same Jupiter chip just made with more expensive technology with minimal gain. This chip loses by design.
Bitfury can do almost the same with 55nm at datacenter level using hundreds of cheap chips.
While KNC is making CPU style chips which all need active CPU fan cooler. Fail from desing, blade style miner with many chips is more cost effective to make + cool.
Big big fail they will lose 2014.

Bitmain next gen. is taping out soon.
28nm and will be next best chip.

 uuuh, yeah.



but best yet is the overclocking forum

So what kind of improvements did they make %wise over what period of time ?

It was publicly known secret from China bitcoin meetings some weeks back or was it held in May. Bitmain were to tape out June/July. Nothing that public... but scene knows they are gonna come out with new chip for very good Antminer S2 unit blade design.

[s1gs3gv]

Publicly known secret from China huh ?

I have no doubt Bitmain is working away on the S3 but that is different than saying that they are taping out *soon*.

They were talking about availability of S2 upgrade boards  in August … maybe this is what led you to believe 'soon'

[tolip_wen]

unproven until seen in wild but,,,

15 days for packaging, not a month, not 2 months etc...

YMMV

[The Avenger]

So they show a picture of cases they've had for months and every sucker believes they are going to start shipping this week!  

You guys never learn.

All that pictures means is no more refunds and to pump sales of batch 3.

We expect to ship to Batch 1 pre-order customers this week

It'll never happen! They couldn't even manage to ship boards they had in stock last year when they promised, no chance they can produce 1200 working rigs in 3 days.

Haha. Ok froget it then.
Lets say they have nothing coming for now or near future. Was offtopic anyway.
tapeout wont be announced

/cheers for all happy customers who managed to get KNC refund processed. KNC goal was datorhall all along.
