We are grief counselors here. Our friends are in one of these 5 stages:

1. Denial, numbness, and shock
2. Bargaining

We're just helping them cope.

I love Sweden girls

My apologies in advance to those who have nightmares easily:

Nvidia delayed SELLING 20nm because the cost does not drop fast enough IN THE FUTURE.
Your implication that Nvidia delayed due to some show stopper 20nm issue is not persuasive.

KnCMiner does not have this concern as long as customers are willing to pay the price.
I very much doubt KnCMiner 20nm ASIC delivery depends on the cost of chips next year.

pixels are not Satoshis and miners expect to spend more per.


YMMV

Something does not compute, because a fine swedish lady from customers support gave an assurance of Q2 shipping 

Do they have 20nm asics ready?

I hear Nvidia has delayed 20nm parts till 2015, and I very much doubt knc can get them before Nvidia does.

Disclaimer:
My calculations below are just guestimations and speculation based on limited experience and sample size.
I would not be suprised if flaws in my reasoning are found.

Also note W/Gh is a manufacturer term for power usage @ ASIC.
I'm currently consumnig another 21% @ the wall (120VAC 90+ supplies).

What KnCMiner has said publicly.
(initially)
43% power reduction.
1440 core per ASIC.
(updated)
Additional 11% power savings spent on more core per ASIC

~1600 core per ASIC

(I subtracted the 11% from the already calculated -43% figure for ~50% total improvement NOT 54%)

currently 28nm 1w/Gh
estimated 20nm 0.5073W/Gh

1600 cores @ current default Oct. 28nm core speed of 750Mhz
3 ASIC, 1200Gh/s each ASIC consuming 608.76 WATTS each.
(that would be like pulling an Elephant out of the hat IMneverHO)
3.6T stock clock

1600 cores @ 500Mhz
4 ASIC, 800Gh/s each ASIC @ 405W
3.2T stock clock

This is doable with heat management on both sides of the chip/PCB.
(based on knowing many 28nm ASIC currently pulling close to 200W 24/7)

They will have to keep adding ASIC till power is managable.
They may add ASIC for other reasons.
IMneverHO it will boil down to how much heat they can pump thru the heatspreader.

Currently the 28nm part has 16cm^2 (40x40mm raised area on 50x50 chip)
A different heatspreader and 25cm^2 is available.
(did they mention a 55x55mm package?)

I'm guessing total @ wall a bit above 2kW
Definately need 200+ VAC circuit for most situations.
A 15A 220VAC(ASSuMEd USA power std.) circuit would be minimum I'd consider for a single Neptune.

YMMV

Never ever underestimate the stupidity of humans...
To quote Einstein:
Two things are infinite: the universe and human stupidity; and I'm not sure about the the universe.

Happy mining!

Are the last 1600 pages just as entertaining?

You are so smooth at running your mouth that you forgot to use the best tool on your body...  You know the one inside your skull...  Or maybe you are having brain diarrhea...

2025

Why is that? I'm not too familiar with KNC, never bothered about this thread as it is too fucking long. Any other thoughts on delivery time?

yeah that'll be me, a man with an opinion, i know it runs against the grain but there you have it.

ADD: I do admit that I took my personal repulsion of Eric Hansen and I applied it to my reasoning.
I was wrong in that I should have just ignored him in the first place. I have not offered you any proof of anything, I feel that proof will show for itself from what I have read in the confidential documentation which was leaked to me, whilst I was researching something along a totally different line.

I also understand the frustration that your hardware manufacturer is screwing you over left and right, while you attack the messenger of bad news.
I'm sorry for your frustration and also for the millions of £'s that your h/w builder is accruing while you are the ones who have funded their greed.
you asked for disruptive? you are welcome.

direct your anger at those who are delaying your profit, not the ones who show it in plain sight.

It is funny (or rather ironic) that you are the one who is acting like the "Know it all" or at least that's what you are so desperately trying to believe that you result into name calling in back-to-back posts.  You know what they say, whoever screams the loudest knows the least...

How much Ego does one must possess to create a new post about a "news" and quoting his own blog as source and proof of this news?  As if that wasn't enough, that said egotistical person has the gut to post a Please Donate at the end..  As if he is providing a great service to everyone.  You are a sad, sad little man.  I am sorry for you.

I know that technical details are important, but what we don't know is what will be the hashing power and energy usage.
At BTC $456, S1 is $2.26/GH with 5day delivery. I want a new cool machine as much as anyone, but it has to be 5 TH delivered now. I would also appreciate some sort of compensation-they are not legally have to do it, but considering the datorhall impact, it would be a good gesture. Something like 2-2.5 TH free from the datorhall until presumably late May delivery for batches 0(CA) and 1. Anything short of this and refunds will continue until only 20-25% are left (according to poll on knc website). I think that they have something coming soon as far as policy is concerned because they suddenly posted that refund problems have been resolved.

I'm not trying to tag team ya here.
fenix and I are of WAY different ilk.
(I'm only a Jr. fanboy who likes to tinker with HW)

My ignorance is great regarding foundry schedules.

Based on my understanding of the link Phoenix provided.
Cybershuttle refers specifically to multiproject wafers.

KnCMiner may have thrown down for full wafers.
(with my money)
Time is money in this racket and the risk/reward may justify the position.
I think that is how they did it with 28nm.

Rather than quip about others ignorance why not educate?
(I don't dispute my ignorance)

Some negative Nancy's have already taken your post about a possible delay as gospel.
(see I am not above ad-hominim either)
Even though it is based on 'confidential sources' and what I consider possibly misleading terminology that does not apply to this situation.

At any rate, time will tell!

YMMV


*EDIT
While composing my post I see you have clearly self identified as a disruptor.
I'll apply Occams Razor as apropriate

odd that they didn't have the hardware that you can purchase now and have in your hands in 4 days. kfc surely can't do that unless it is for themselves. coindesk really is turning into some waste of internet space.

sorry, no, it's most definitely, the step after t/o...

"CyberShuttle® services break the barrier by letting multiple designs share tooling costs through a multi-project mask set. "
and
"CyberShuttle® services also validate the sub-circuit functionality and process compatibility of IP, standard cell libraries and I/Os."

Thanks,

I did miss it...
