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.

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

I know that technical details are important, but what we don't know is what will be the hashing power and energy usage.
---SNIP---

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
Smiley

I have only 15A/120V circuits where I want to host it  Undecided, but I can probably use two of them, though; each should be enough for 12.5X120=1500W
I cannot use the"sacred" dryer (240V/30A) circuit, hence I can only host one Neptune in the best case scenario.

Nvidia = Global Foundries (some of which left GF and Nvidia for CoinTerra)
KNC = Allchip, TSMC, AST, ORSOC, and Their own specialists on dc/dc(KNC) with Markus Erlanderson's code.

...meanwhile TSMC and ARM have announced tapeout of a 16nm already....
http://www.extremetech.com/computing/152382-arm-tsmc-complete-16nm-cortex-a57-tape-out-chip-launching-no-time-soon

So,  "knc can get them before Nvidia does."   a big yes.

Nvidia's competition, AMD uses TSMC.
http://wccftech.com/amd-tapes-20nm-14nm-finfet-chips-1h-2014/
*and they @ AMD have a long history of beating Nvidia to market with the next gen GPU's.

and whilst a GPU may be an "Application Specific Integrated Circuit"(ASIC)...
A GPU has a multitude of varying tasks to perform, while our Miner ASICS are redundant of a single task.
Which is why it will take much longer for the GPU's to be developed in comparison to Mining ASICs.
Hope that helps clarify things.

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

Nvidia is usually a good 3-6 months late jumping on a new node and AMD are almost always a few months ahead of them. For gpu manufacturers yield is also a lot more important since it's more costly to start disabling cores due to the way they are grouped up.

Also there seems to be no performance/$ gain at this time going from 28 -> 20nm, so best case you are looking at higher density and BEST case better performance/watt. Remember we are comparing a mature node vs one that is at this time quite untested (It took nvidia almost a year to get decent yields and fix leakage on fermi GTX 480/580 for example) Considering all of this you see why gpu manufacturers are in no real rush to jump on the bandwagon.

Poll....

Think it took me around 2 weeks.

Nvidia = Global Foundries (some of which left GF and Nvidia for CoinTerra)

Nvidia is as far as I know still using TSMC and has been for years, AMD however might have shifted some of their gpus over the GF (I've not really kept track)

The gpu is also an ASIC, so of course there is a clear comparison to be made.

Most(all?) GPU are not ASIC!
At one time that may have been true, not now.
Within the last 10 or so years GPU's are commonly applied to other 'applications' unrelated to pixels.
They now come with instruction sets and have IDE's available.
Just doing some of the physics calcs negated the ASIC rule.
They were not specifically designed for sha256 but many do it.

Does not sound like they are 'application specific' to me at all.

I suppose clarity of comparison is subjective.
I see more differences than similarities.

Comparisons can be made.

sha256 ASIC communicates with perepherials over serial interface.
GPU must communicate with perephials(external memory) over 128, 256, 384, or 512 bit wide parallel interface.
(orders of magnitude difference)

current sha256 ASIC needs about 200kHz communication speed to keep up reliably.
GPU needs much faster speeds to communicate with memory.
(orders of magnitude difference)

most sha256 ASIC core run at between 0.5 and 2 MHz clock.
GPU run at over 200MHz clock
(orders of magnitude difference)

To name a few (orders of magnitude difference)

YMMV

You're not going to have to worry about that.  You're not getting a Neptune.  No one is.

Which means shipping in August according to past history.  Maybe July.

The other interesting info from this:

"Bitcoin will by charging their customers a transaction fee of 0.02% passing through the nodes of Constance and through that to ensure one million investment in women's handball in Boden."

So not only the regular bitcoin transaction fee, knc are going to be scalping 0.02% off every transaction that goes through their KNCWallet (now you know what it's for).

So when they say they are offering free 6 month cloud hashing, it's also a lie, as they'll be scalping 0.02% fees off every payout.

In the conversation I had, prior to my receiving the document, almost every mining h/w manufacturer was discussed, I wanted to gleam as much information as I could. So yes, KNC were talked about - but the full info is more generic, and covers many more than just KNC.
I can only presume (thanks avenger, that gave me a giggle) that KnC knew all about the mask-schedule, as the document I have is the same as they would have received prior to deciding where to tape-out and with whom...

sorry but i'm moving on to another story now, so take all this as you will. i work in the news and this is now yesterdays news. the article i've written has been put round my list of editors and it's now up to them; if they want, to run it.

by the way, for info, i'm a miner myself and i've been just as screwed over as the rest of you. so please, don't shoot the messenger.

yeah but in this case the messenger has info. that the rest of us DO NOT,  so shooting the messenger at this point should be allowed, ok well at least some water boarding, that's not torture, right! Shocked

Well in case anyone is wondering, they're still processing refunds without problems, I just asked for a refund of a Neptune (CA batch) and they said it'll be processed shortly...
