Due to repeating questions: SP30 AC/DC Power Supply unit guidelines - SP30 PSU |
|
|
|
Are the chips on track for late July units delivery?
How long do you think packaging will take?
Yes, about 10 days |

... Hamas is going to blow the fuck out of my $100,000 investment? I sure hope bombs flying overhead doesn't slow down production much. ...
Son-of-a-bitch!!! Now they are shooting from Lebanon too!!! Please, please, please don't hit the miners at the shipping facility.
What is your order number ? |
|
|
|
Maybe Spondoolies should move to China. Could help with their lead times in ordering parts.
The longest lead time part is the ASIC. It has nothing to do with China. |
|
|
|
I guess that explains why I haven't received a response from Spondoolies' CS, you've been preoccupied with more pressing concerns.
Glad to hear that you guy's are OK.

I've seen the email, we'll reply. Regards, Guy |

We'll ship on time.
So we should be getting some SP30 reports in from the field before the end of July, eh ? Yes |

To all the well wishers, from past experience, the round of violence will end in a week or two.
We'll ship on time.

Howdy Forum, I thought I would introduce ourselves as Seattle Data Center owners. We currently have over 2MW of miners in place and have been deploying a lot of individual machines recently. That said, we have learned a lot and we're happy to share our knowledge from a data center facility standpoint. • Market Knowledge – http://dfcolo.com/bitcoin_terraminer_hosting/ o 2 MW of Bitcoin Mining operations currently under management in our datacenters. o With significant time and resources spent learning Bitcoin mining operations we have become well versed in this segment of our industry. We know how to anticipate and respond to your requirements based on extensive hands on experience in this industry. o Currently have hundreds of Spnondoolie 10’s plus many Antminers, Terraminers, KnC boxes and custom deployments in service. o Can, manage, deploy setup machines plus configure private VPNs, firewalls and DDoS protection as needed. • Infrastructure Seattle– o 2N 1.5MW Caterpillar diesel generators with 3 days of fuel on site o N+1 Cooling on pressurized 24” raised floor o VESDA smoke detection and ECARO fire suppression o 24x7 onsite staff, support and remote hands o Low latency redundant fiber backbone o Custom realtime RFID temperature and humidity monitoring o True Green State, with Green Hydro Electric power • Culture – o Profitable and well-funded managing over 70,000 sq. ft. o Long history in this community and are building a company positioned for ongoing growth and longevity. Video Tour http://dfcolo.com/seattle-data-center-video/ Call Kevin 877-720-0483 - 206-681-9732 info@dfcolo.com I confirm that our customers has hundreds of SP10 hosted by Digital Fortress. Guy |

To all our customers (even the unreal provocateur ones) - we're ok. We got a lot of heartwarming emails and we wanted to thank you. It's not an easy situation for us, but we'll manage. Rest assure that the orders will be shipped on time. Some facts: - Our houses and families are within range of the missiles. Most of the population are. - Our offices are about 100 meter from Intel 22nm Fab (soon 10nm Fab), which means that we have excellent Iron Dome coverage. - Flextronics manufacturing plant is in the far north, well outside the range of the current conflict. Shipping is done from there. - The mandatory enlisting of reserved forces is minimal. None of our engineers and employees have been drafted. Guy |

How does 55nm chip cost compare to 28nm?
My understanding was that wafer cost would be cheaper, but you obviously have to use more area per GH. (Is it therefore around the same price per GH?)
Wouldn´t packaging costs be higher when you have more chips to package (or is this a very small difference)?
PCB design would probably be easier as you could go with very small heatsinks etc.
At the end of the day, Bitfury is probably already very limited by the 55nm process, as he probably has most of the optimisation done by now (in his 2nd ASIC generation).
On the other hand Bitfury has secured a $20m funding round, and some of that will most likely be used for NRE of his next generation chips.
I'll answer your basic question and then elaborate a bit. If you compare the same design: 28 vs 55 nm wafer cost ratio is about 2:1 Area ratio is (55/28)^2=3.9 Speed ratio is about 1.5 Total $/GHs ratio is 3.9*1.5/2=2.9 Totally in terms of $/GHs 28 nm chip should be about 3x cheaper than 55 nm As it is, you don't compare the same system design. BitFury design doesn't use DC2DC. They're using a "string approach", similar to Christmas lights. The ASICs are constantly pulling 2 Watt, even when doing nothing. We've analyzed this approach and decided to keep using DC2DC in our 2nd and 3rd gen systems, despite the cost and supply chain challenges. The reason is that in overall $/GHs we're getting better results. BitFury isn't sitting idle. They scrapped a 28 big ASIC effort due to thermals challenges (unconfirmed) They still didn't TO their custom 40 ASIC (the ASIC is confirmed, the TO status is unconfirmed) And of course, they're working on advance nodes as well for 2015 (confirmed). Interesting times ahead. |

It seems that BitFury started massive deployment of their LightFury script ASIC: https://bitcoinwisdom.com/litecoin/difficultyThey completed deployment of their 10MW DC in Georgia in 4 weeks, and they probably allocated some percentage of it for deployment of their script ASIC. Nasty surprise to KNC and Titan buyers. It will get much worse. It would be very helpful for litecoin price  In what direction ?  |

LightFury, not LiteFury. 55nm fully custom scrypt ASIC, developed by BitFury CTO. |

Well, bitfury is king and anyone who underestimates him is always in for a bad surprise I would like to get your professional opinion on this: Bitfurys 55nm Asic uses "experimental low voltage transistors" and is apparently hand-routed. Would their performance not benefit from die shrinks? We've seen all the three 55nm ASICs dies. All are custom made. Impressive work. More impressive since Valery Nebesny is self taught with software background and without any formal ASIC design background. Doing custom to 40 and below is much harder. In PickAxe and other ASICs we're doing, we're taking the 80 - 20 approach, customizing the cells that give the most benefit. Still using automatic tools for the routing. Edit: BitFury is using UMC for their 55nm ASICs. UMC is limited in advance processes compare to TSMC |

No false advertising. Just a pissed off AM SH (my favorite) waiting for his (her?) dividends. |
