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.

quoted for future lolz

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

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....

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.

+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.

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.

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'

unproven until seen in wild but,,,

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

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

You guys never learn.

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

Quote
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.

All you have to do is to look at the respective offerings of the different players in this arena to figure out who is data center oriented and who isn't

The Swedes are obviously into BauHaus and the modern Scandinavian architectural movement. Very funky physical design !

no, no address changes without begging, pleading, groveling, and insisting you moved after the packages have been returned to sweden.....
The no address change thing costed me thousands.

I luv how everyone judges the cuisine before it's served. Adds a bit of spice....
5 box Neptunes... (Giggle) On Raskul's word....    they never even got a chance to post the actual release specs yet, and raskul didn't post that e-mail... rule is... no post= it never happened. Let's see that email!

10 k for 3 TH and 5 X-boxes?


FAIL.


Huge FAIL indeed.... they could have delivered that in simple 28 mm ....

Under promise and over deliver Huh  .... Bullshit !

I luv how everyone judges the cuisine before it's served. Adds a bit of spice....


Enjoy your meal.

It might be spicy, but it is still shit.
