This is more possible.

I can see there is the pcb board inside with the pci plug.

But probably no chip.

There are several different types of Bitcoin clients. Header-only clients like MultiBit trust that the majority of mining power is honest for the purposes of enforcing network rules such as the 21 million BTC limit. Full clients do not trust miners in this way.

Maybe, time will tell.

Probably Neptune will ship before some refunds are processed.

Finally looks like they will deliver within June.

But why don't they give some specs/info about their progress?

There is something behind.

Its quite common for them, remember what it was like on the run up to Jupiter launch?

As far as I am aware, they are still testing the boards and software to get optimal results, once they have something stable they will probably post.

Going to be an interesting week for those who have orders.

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?

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

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.

We have yet to see the final product, so its all guesswork fro now Smiley

How do you want to split 5 into 2 ?

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 Wink

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 Tongue

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

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)

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.

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

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