Fair point on Cheap hyrdo power in China eg the 3 Gorges Dam but frankly, that vast majority of overall power production production is spoken for. For most heavily industrialized countries, for just one segment - aluminum production - takes one helluva chunk. ref: http://wordpress.mrreid.org/2011/07/15/electricity-consumption-in-the-production-of-aluminium/
"According to Alcoa, the world’s largest producer of aluminium, the best smelters use about 13 kilowatt hours (46.8 megajoules) of electrical energy to produce one kilogram of aluminium; the worldwide average is closer to 15 kWh/kg (54 MJ/kg).

Worldwide production of aluminium in 2010 was 41.4 million tonnes. Using the figures above this means that 621 billion kilowatt hours of electrical energy were used in the production of aluminium. To put that in perspective, the total world production of electrical energy was 20261 billion kilowatt hours, meaning that more than 3% of the world’s entire electrical supply went to extraction of aluminium."

Toss in the other more pressing power needs of China and you get my point.

Ja certainly a lot of low cost power will be available to local (ish) peta-farms but not as much as you think. Outside of being right next to the power plant/dam (the now closed Alcoa smelter site in Washington state comes to mind) the infra over there just does not support someone suddenly deciding to run 25-50MW much less 100MW or more without a helluva lotta prep and time/cash for it to be done.

yes but we had  2 months of huge see-saw hash rates. In Nov and in Dec.

Seems to me  China (bitmaintech) has been setting up this flood the network work idea for quite some time.

They only need 5 months or so of cheap power to do what I am saying.

Maintain a 15 to 20% growth rate until the ½ ing

 They do not need 1x  100 mega watt deal from 1 dam

3x 40 mega watt deals do the trick.  Or 4x 35 mega watt deals.

Remember China has been having an industrial  slump and some of these plants may have excess power.

I picked the biggest dam  because what is 100-150 megawatts compared to 22,500 megawatts

less then 1 percent.  Basically if this is the  tactic being  employed.

 1 cent power with .3 watt machines

A bitfury  owner need 3 cent power with .1 watt machines

both costing the same per th to be on equal ground.

And the bitfury may not be ready until april 1st (hmmm is that a joke)

by april first diff will be 293 -300 and a 10th 1000 watt machine would only be earning 4 usd a day with 10 cent power
and 5.20 usd a day with 5 cent power

And the ½ ing would be 5 diff jumps away.

Of course maybe my FUD about the diff is wrong and after this jump to 170 we go flat

Or back to more normal jumps of 3 to 6 %

Great contribution to the community! Thanks!

I was hoping for chip design actually when I saw the thread  Smiley

48V will be a plus, much smaller section needed for PCI cables.
Does Bitfury try cooling those whit transformer oil? not two phase, only transformer oil cooled whit a radiator.

189 chips/board x 25Gh(BF 28nm - 32GH)= 4725 Gh/s / board at 0.2 its 1kw/board, is that correct?

i just saw their spec 1700 hash chips = 20TH/s so 11 Gh/chip 2200Gh/s /bord - 450W

StringPowerBlock.pdf is probably the most interesting one. This is a block of one 250nm communicator chip and seven 28nm chips. Here you can see how the individual blocks are interconnected (differential pairs), hashing chip connections and how the StringPower design that BitFury pioneered with our first 55nm chip works.

Is the chip named Bitfury_POWER in StringPowerBlock.pdf the one that is on the boards (on 1block_short.jpg BF250K3N48), because the pin-out is different - 40 vs 56 pins
If it is the same "250nm communicator chip" but different revisions or the bigger one is just for more chips, which of them is the latest revision and for how many chips?

BitfFury is deeply committed to a decentralized Bitcoin Blockchain ecosystem and we want to do all we can to ensure that as many hobbyists and engineers as possible have access to the technology we have developed with the support we've had from the Bitcoin community. Therefore we have decided to release our 28nm designs under Creative Commons Attribution Share Alike 3.0 License to give you the opportunity to get familiar with the style of our latest designs.[/size]

I am sorry, but I find this move to be FULL OF SHIT.

You are releasing your 28nm designs when you already have a 16nm chip out in the wild. Economically this is useless. If you wanted a decentralized Bitcoin Blockchain you would've release this last year, not now.

PLEASE STOP LYING ABOUT YOUR DECENTRALIZATION EFFORTS.

I do applaud Bitfury for making a presence on the forum, I hope it is because they are truly committed to us "little guys". 

Really? Are you for real? Nobody will buy these chips when they are less than 1 month away from mass deploying their new 16nm chip that needs less than 0.1W/GH. Please stop with your shilling!

Dude, stop being so naïve. Brownnosing to chip vendors is nowadays the only marketable skill for non-technical people. Bitcoinorama is now back posting, go reread his story. Maybe he finally got paid by KnC?

Shill is actually a highly honorable occupation centered around getting paid by the vendor.

And getting paid by miners like me. I've thrown a big fat tip towards him for his view on KnC when they were accepting pre-orders for 1st gen Jupiters once it was proven that he was right. It seems that I scared him and he stopped posting now Smiley

I seem to have missed your point.  I am not referring to this thread, I was referring to them posting on this as well as the 16nm thread.  They have stated they will release the 16nm chips to home miners.  As for your last statement "shilling" - whatever Huh

16nm chip will work on 28nm boards.

"So from 1 UART connection we're able to service up to 1700 hash chips (over 20TH/s with our 28nm chip and even more with the 16nm). 16nm will work in a very similar way."

I would assume they are releasing the board info so engis and small companies can prep designs to incorporate their 16nm chip....

They haven't released anything...those are just pretty pictures to look at. From an engineering standpoint you need detailed datasheets, pinouts, and IC footprints at minimum to begin laying out a board. Maybe you can get a crude schematic together with the info they have released but thats about it.

If that were the case then people wouldn't complain that you need to send them at least $1M to get the info about their new chips...

Bitstream or GTFO....  Cool

Now seriously, on your next 16nm chip you need to do two main things, if and only IF you want to dominate the bitcoin mining business:

  • Sell it on small quantities: 3-packs (no problem with markup here) or even have a sampling program (look at TI's or Microchip's program, you get the drift). TSSOP or QFNQFP versions would make you my personal heroes, like, really heroic.
  • Release a GOOD, CLEAR AND INFORMATIVE SPEC. Bit-level timing, SPI commands, application notes with usual circuits for working the chip.

These two points aren't really that hard, and would show your commitment to a real decentralized, hobbyist oriented business. I just want to get my iron, solder and create my own money making machine. Is it that too much to ask?

I fully agree on the info release aspect.
How do chip makers like TI, Linear Technologies, Intel, BM, et al sell their chips? By putting out data sheets and offering sample lots of chips and eval boards.
