So you have to lay down a $1M order on the chips sight-unseen in order to get information about the chips? Either that's not correct or that's powerfully stupid.
"punin"/bitfury is saying that he will have smaller batches on "my site" without mentioning what "my site" is.
probably just bitfury's main site.
He also says that they currently have 98 chips (had 100, burned two by going to 180 Gh/s in immersion!).
Mass production-most likely late March-April (without overpay for a "hot lot").
Engineering schemes delivery in late Feb to those who pay now.
For 100+ GHs per chip you'll need a heat sink
From the info already in the open air I'm planning to do string design , but kind of a hybrid with DC/DC group just to play with the Voltage
There is no chip specs yet .
A lot of open questions like Chaining of SPC ...
I think we can trust that the chip is tailored for a string design.From the info already in the open air I'm planning to do string design , but kind of a hybrid with DC/DC group just to play with the Voltage

A lot of open questions like Chaining of SPC ...
Are there no seperate VDDio and VSSio pins?
Weren't the BF3500 and BF4500 based on one of their 55nm designs?
Yeah, I think so. And there have been some "out in the wild"
Weren't the BF3500 and BF4500 based on one of their 55nm designs?
Look at previous boards and the board in the test - they're almost bare.
Are there reference designs or public information regarding any other than the 55nm bitfury generation? It would be a waste not to put a heatsink on that chip - or immersion cool it, like they do themselfs.
AFAIK no ones even benchmarked a 28nm chip in the wild, every machine must have been sold under a solid NDA or mandatory purchase order. Its pretty crazy if you think about it, 1000s and 1000s of BF3500s and BF4500s and not one has ever been 'tested'.

I guess they will sell the chip with respect to the nominal speed of 100 GH/s for $13. But at this operation point you will not have 0.06 J/GH.
Yeah my interpretation is its more of a headline efficiency which could be used in the second half of this gen (like S4/S4+).Anyway, this would still be a good price.
$0.13/GH certainly isn't terrible when you consider how cheap their reference design is to make and should allow the OEMs to get by at least for now.Have you got information regarding the reference design or are you just guessing?

For engineering it is OK

That's the price of the efficiency! The chip performance is low.
I guess they will sell the chip with respect to the nominal speed of 100 GH/s for $13. But at this operation point you will not have 0.06 J/GH.
According to their press release it should be approximately 0.12 J/GH instead.
Anyway, this would still be a good price.
So air about 140-150 tops with heat sinks and stuff

Meaning: They pushed the chip to 180GH/s before it died... Immersion cooling of course.
To my knowledge BitFury has remained pretty silent on this chip as far as development and integration goes. As with basically every other BitFury announcement we should probably assume this chip doesn't exist until we see concrete proof of it in action.

Cool! Thanks for showing me this video

And those who have looked at them an know a lot like Dogie mentioned are under NDA.
[I'm not under NDA with them at this point]

NDA for pricing is OK
For technical docs no so much.

No - all you gotta do is make them believe you might, and btw - they are willing to show you the chips.
I think making them believe it is not going to be as easy as this sounds. I think they will look up past projects and if you are not a huge bulk customer like you mentioned 1 million (possibly less) they are not going to even talk to you.
And those who have looked at them an know a lot like Dogie mentioned are under NDA. So we really have no idea who has seen it or what plans are. I don't expect NDAs to be lifted anytime soon. I bet they want to make their own internal miners, and chips to sell to those who bought in. After that if they need more customers maybe NDA are lifted and we hear from more people.
Could be wrong though, since the 3D FinFeet should lower the power need even more, but still a hughe bump up going to have a 20TH miner with 1500Watt power.
Looks like these chips are TSMC chips with an output of 1.750 Watt for a 25TH miner, excact same output as Yesminer chips.
I wouldn't count on that

What's the means of contacting them in order to start those hoops? I'm having no luck so far.
You need to order chips to the tune of ~1M$...

Actually there is Zero info for a designer to start working on a miner board at the moment 
Its available under NDA almost immediately, and test chips after a few more hoops.

Hello all,
we are playing with the thought of buying Bitfury 16nm chips - and I'm sure we're not the only ones... Is there anybody with a proven miner-production track record wanting to partner up, increase the volume a bit?
It's of course a pretty early stage and still significant details are missing about the chip to make a design. Anybody interested, please let me know
