Seriously guys, use some sense. They posted the first real life test results from an ENGINEERING SAMPLE and suddenly everyone is claiming they just deployed 100PH of them.

yes, that was more (for at least 180Ph) due to "40MW energy efficient immersion cooling data center" launch: http://bitfury.com/content/3-press/2015-12-16-tbilisi-data-center-fact-sheet.pdf


now regarding the 16nm chip: http://www.businesswire.com/news/home/20151216005453/en/BitFury-Announces-Mass-Production-Fastest-Effective-16nm

After rigorous testing, the new BitFury Chip has demonstrated outstanding computing capabilities. The design target was 40 gigahash per second with power efficiency of 0.06 joules per gigahash. On average, the measured power efficiency of tested engineering samples of the new BitFury Chip ranges from 0.055 joules per gigahash to 0.07 joules per gigahash, thus making the BitFury 16nm ASIC Chip the industry leader in energy efficiency.

In addition to its outstanding power efficiency, BitFury’s 16nm ASIC Chip can run with as low as 0.35V power supply voltage. The static part of the Chip can be functional at as low as 0.28V power supply voltage. This level of productivity was previously unattainable with existing silicon devices and existing silicon design methodologies, with transistors working in active mode, not slow sub-threshold. J / Gh metric in working modes starting from 55 Gh/s up to 180 Gh/s follows an almost linear relationship of 0.0011, while at 40 – 55 Gh/s measured slope converges to plateau.

Every BitFury 16nm Chip delivers a minimum of 100 gigahash per second of computing power. On average, the BitFury 16nm ASIC can compute in the range of as high as 140 gigahash per second using air cooling, and up to 184 gigahash per second using immersion cooling, which makes the BitFury custom-made silicon an absolute leader in computational efficiency per unit of silicon area.

It wasn't my intention to claim such. I'd love to buy bitfury stuff again, but we are not in 2013 anymore and the chip has to be really incredible to make sense to sell it to the public.

[Mitak]

If it is 20% better price USD/Ghs and 20-30% better in terms of W/ghs @ the wall and better Ghs/sq.mm in miner PCB than Bitmsin snd Avalon then there will be market for this for sure

Bitfury chips have been that way since gen1.

rev1 (55nm)(Sept 2013): 0.9-1.2w/GH, improved slightly by the first ASIC string for bicoin mining. Sold as a barebones miner that was easy to produce and could work without heavy/costly heatsinks. about 2x the efficiency of the competitors
rev2 (28nm)(Feb 2015): 0.2-0.3w/GH (4x gain), pretty much exclusively private deployment. about 2x the efficiency as the competitors
rev3 (16nm)(Feb 2016?): 0.05-0.07w/GH (4x gain), hopefully they sell to public

these guys have been the smartest group so far IMO, opting for high-density designs that run in string (less DC/DC components) and dont require heavy heatsinks, only a sparsely populated PCB. deployment to an immersion system would be fast for hardware like this, and the string design could allow operation from >12V power. I would not be surprised to see thier in-house hardware operating with 48VDC power supplies for density

[klondike_bar]

But in the same time first unit did an excellent ROI.
My 25 GHS starter kit delivered 1-st of Sept 2013 made 4-5 times ROI by the end of the year

Also bought some chips and used assembly service for them 1-st gen
Got 3-4 times ROI

So  in fact all my bitfury based gear made ROI

Quite different times when ASICs fist came out back then, but that is good to hear they ROI'd so fast the first go round!

I think the only reason he "ROI'd" is because of the run up in Nov 2013.  He would have likely done waaaaayy better buying BTC In Sept and holding.

I got a september kit and more boards in november and made an ROI (paid with $120/BTC though). I cant recall the exact numbers but i think i spent like $2900 (~25BTC) and the return was $6000 (~16BTC) over something like 14 months of mining (i didnt sell many coins above $700) which is pretty good considering it ran more efficiently than even an undervolted S1

sure, BTC investment would have been a better faster return, but i view mining as a leveraged risk. Hardware i bought when BTC>$800 made ROI (or very close to) because the difficulty stagnated with the dropping price, whereas holding BTC would have been 40-60% losses during that time

Will be reopening the shop soon! The chip is crazy and amazing. Anyone interested in H-cards with 16nm chips?

Thats a name i haven't heard in a long time...

Id love new h-cards! But at the same time I think an assembled, standalone unit similar to the S1 or S5+ would be great. keep the lightweight, barebones style, just include a basic frame to prevent wobbles and a pair of fan brackets

I think it comes down to chip cost and overclocking feasibility. Gen1 could be pushed an extra 40% under the watch/modification of advanced users, or run with almost no added cooling (heatsinks or fans) at stock.

Or rectified mains;)

[sidehack]

Except without good PFC the utility provider would murder them.

Except without good PFC the utility provider would murder them.

Datacenter PSUs usualy have good enough PFC and rectified mains is almost PFC 1
The higher the voltage, the better is efficiency - compare some high power PSU spec it goes from 83% to 90% for the same class for 12V and 48V.

According to their press releases the datacenter is running on green power - solar or probably mostly wind. The solar is almost at constant voltage, so a string built for that voltage directly, will not need any power management parts, but ... no sun no fun. The wind turbines are usually working at 600-700V AC, which is too much for a string, just because it will be too long for the SPI communication - there is a 17ns per chip propagation delay (for the 55nm chip), which makes the longest chain 300-400 chips max if it is a single string for both power and communication.

My guess is that they are using 12V strings, because at that voltage the power is distributed/balanced directly from the chips - no other components, while for 48V you will need to use the current mirror (which is built-in in the chip) and that means some more external components even if cheap.

I would be very happy to see those external components made internal for the next revision (the 16nm one which may be considered current), because it is possible (for most of them) and will even work better in that case. The only problem is the communication again, because for 12V the string will be close to the limit and the best voltage in that case will be 5V

[sidehack]

Rectified mains is almost PFC 1 (where the "almost" is because of diode losses) but it'd be completely useless. Add a capacitor filter across it to get a regular voltage that doesn't swing from peak to zero 120 times a second, and suddenly your current waveform is evil - that is exactly why datacenter PSUs have good PFC. If you tried to run multiple megawatts of capacitor-filtered rectified mains, well, good luck. Maybe if they used an active PFC unit in standalone as a constant-voltage DC supply? That could be interesting.

Higher voltage tends to be better efficiency in part because of resistive losses. The same power in a high voltage means much less current; relatively fixed-voltage losses like diodes or BJTs would decrease power loss linearly but a lot of things are resistive losses (power FETs, inductor windings etc) which lose power proportional to current squared. Quadrupling the voltage reduces current to one fourth, which cuts resistive losses to one sixteenth. Same applies to the efficiency gain of running supplies on 240 instead of 120 mains, especially for active PFC supplies; less current is required through input boost components to get the required power to the output regulator.

Good chip info. I never worked with the 55nm stuff, didn't even own any until a few months ago so I don't really know much about how they behaved.

If you're referring to the one in Georgia, Georgia is about 80% hydro and 20% geothermal.

55nm was great gear. the system provided chip-by-chip feedback that only spondoolies has been able to exceed (and took an extra year to produce). cooling the h-boards was easy with 120mm fans and you could easily apply stick-on heatsinks sourced from ebay/alibaba/etc to allow pushing well past 25GH/board (required pencil mod)

Hope to see the H-Board back in action! 

[wttbs]

We have a M-board + H-board(s) based on the Rev 2 Bitfury. Very efficieny miner and some our miners are running stable over a year 24/7 without any problem. If anyone is interested in the design send me pm, maybe with some small changes to the design you can make it work for the rev 3chip.

[valkir]

Do you plan to make new board with the new chips ?

[wttbs]

Do you plan to make new board with the new chips ?

No, we stopped our business but the design is for sale so other people may build a new board with the new Rev3 chip. I can't guarantee it will work, I don't have the technical knowledge. But if the Rev3 chips has the same string design as Rev2 big chance it will work with some small adjustments to the design.

[sobe-it]

Only if the footprint is the same.... and similar comms. I have a bunch of h cards with the chips pulled. Possibly a few tweaks to get the voltage right, man I would be ready to rock. But one can only dream right?

There are many ways to skin a cat ... ad some super caps ... one for every 4-5 chips ... the rest will be done from the string itself, if you use the built-in current mirror.

Didn't know that, thanks for the info. Then neither of them (several kV) is good enough for direct rectifying for miner use.

That is the problem - 6-7W per chip seems too much for the same footprint, but if you let me share your dream ... I also have some boards, which if the chip has the same pin-out (and footprint) will work great at 3.3V instead of 12V with just a minor modification

EDIT: 3.3V @0.4V per chip or 5V @0.6V per chip
