Topic: Bitfury: "16nm... sales to public start shortly" - page 37. (Read 108588 times)

Why would they remove 28nm stuff when its already paid for and still profitable? The answer I guess is capacity and just how many data centers you want to build, but that's part of the reason they want to sell these to others.

^^ The possibility of the package size and same limited coms setup makes for an interesting thought: Perhaps aside from some changes to the support chips to handle higher throoughput, the new chips could basically use the existing hashboards or at least most of their already validated portions perhaps? Hmmm..

That would certainly speed deployment in BitFury's almost mobile mini-pharms http://bitfury.com/products#container-datacenter and the new DC... Once more than just engineering samples are produced, tweaked hashboards tested and the foundry is given the the green light to start a full scale run(s) it's then just a matter of changing tankfulls of boards one at a time. If the data tanks are removable as a unit, all the better. prep/change over tanks to the new 16nm chips & boards  off line and swap out the old ones with the new. Rinse & repeat as desired & production (and money) allows for.

Should give their selected integrators a leg up as well I'd think.

A last thought on why deploy 28nm in the new DC: Time to produce enough boards/chips to fill it. The building & all infra itself was completed how long ago? (seriously, when?) With 28nm chips in production at the time or left over from the final runs, why not? Is a good CYA to start filling/using the DC until the 16nm chips start getting made en-mass which is, um, now if I've read things right.

Query to BitFury: If I may ask, how many boards & chips are in each tank? Based on the stated 100GH/s a 12Ph mini-farm takes 120k chips. What size wafer is used? What is the actual silicon die size (along with full package size?

How do the COMM chips connect to the external world? Will the 16nm Bitfury chip be available in QFN package?

I don't see how it would be possible to produce full working miners meaning PCB+chips+components at $0.06/GH. Even if this were true, which I find very unlikely, the big private buyers are being ripped off big time while we are being lied that BitFury is trying to help the decentralization.

If you think there will be a 5TH/s miner being sold for $300 within the next week then maybe you can hit ROI with those numbers. Doubt that will ever happen. It needs to be ready to hit the market at half the price of an S7... today.

Please correct me, if I'm wrong.

Let's assume they
1) produce a 28nm miner for $0.06/GH
2) operate it at 0.36 J/GH (conservativ guess)
3) while having electricity costs of $0.05/kWh (or less)

they should make $0.03/GH per month at the current difficulty, which means ROI in about 2 months.

There will be probably first miners based on Bitfury's 16nm ASIC in wild and their DC end of March, but I guess the real volume ramp up will happen in April.
So it should be enough time, to make some profit with the new 28nm hardware.

Then it becomes a write-off. Hell, stuffing the DC with 28nm chips could be part of their R&D budget...

Sure, but doing that needs money and the difficulty is raising like crazy. They will never make ROI on the "miners" so that means that they have money to burn just like I said. I understand that they need to get the ball rolling and that they need to test the DC, but if the 3rd party manufacturers can get miners shipped in March then they can get 16nm miners in the DC too. There is simply no time to make ROI on this 28nm miners.

Just my take on it but: Because one has to start *somewhere* and get the ball rolling. The older chips were on-hand and they have working boards for them. As a bonus they get to test the DC at full load.

Newer more efficient chips/boards are in the pipeline but not on-hand so you either have a DC sitting there empty/partly used or ya plug in what you have right now and upgrade when the new designs get into full production.

I think I would have put something in there about price... I mean those 50TH could cost 30BTC depending on availability.

Why would you spend money on filling a DC with older gen chips especially when you will receive the newer chips with MUCH better efficiency beats me. You either have money to burn or you will simply build a new DC for the newer chips or you simply pay so little to do this that you can afford to replace everything in 1-2 months. I can understand filling just a part of it for tests, but a whole DC...something doesn't adds up.


That was a very bad bet from my point of view. You just made a bet with a manufacturer who can simply get this in time by liaising with a 3rd party who can sell a small number of miners. Maybe the miners will be built by BitFury and just sold by the 3rd party company just to win that bet.

I put a copy of this for reference

Hey, we're an audited company now! Gotta track some assets

Nice:)

Is there an NFC circuit on this board?

Deal!

It would be hard for him to make that bet IF BitFury is not the manufacturer of the rig.  It's too hard for him to know when another manufacturer of rigs using their chips will actually ship.

Good point by you and Dmwardjr.  - But let's see if he actually wants to bet or it was just advertisement 

Should be a given but also add, "On promised delivery date at time of order verification (eg. yer wallet says the Tx went through and has a couple verifications or check/other fiat xfr was approved) subject to strictly defined definition of "Late/delayed" and resolution process if late or delayed"
This comes to mind on both points:

Ordered mine Feb 28th 2014 when it was not pre-order but instead "delivery in 4-wweks or less"... We all know how the AMT/Bitmine.ch A1 saga is progressing for most folks...  

I would also make this bet. Either way I win.

Don't forget to add, "In good working order and according to specifications."
