Topic: List of upcoming 28nm ASICs and estimated shipping date (Read 2202 times)

Is it just me that thinks WIKI technology is grossly underutilised?

The current price/ chip of the BA chip is 199/100ghash, as a heads up

Give me an example of the way you would like to see it.

Please group these by chip.

Oh... my fault, sorry. I thought it was about the current generation in general. Any source on Bitfury already working on 28nm for next gen?

BFL / Josh has posted it will be anywhere from 17 to 19 weeks from now till their Monarch 300 Gh/s ships.

SPOT THE INCONSISTENCY IN THESE SENTENCES.


That means 2014 March or April not December. Change it.

I suggest that BEGIN shipments is code for keeping units in house and saying they are SHIPPED or shipping unproven prototypes to media yet again, while the bulk of real customers orders go out in March / April 2014 and probably much much later when BFL invariably fails to get their chip package to work on the pcb do to heat. You think they had issues last time? Imagine what is going to happen with the 28nm. Mark my words package redesign for the chips and board redesigns will be happen again. Do not buy from BFL.

No doubt, but that's too far off to entertain at this time. I would like to be one of the first in line for KNCs next offering.

KnC gen 2 is going to smoke.

Cointerra seems like the winner, although it's 6k for a February order, not January, best I can tell. Have sent them in inquiry about placing an order. Thanks a lot for putting that together.

simple comparison of some coincraft and cointerra specs, some are chip related some are rig related...

1.  chips - both fabbed at globalfoundries 28nm process.  both anticipating silicon arrival in december
2.  coincraft chip specs claim 0.65W/GH  Cointerra claims 0.6W/GH/s.  not much difference.  both are claiming at 0,765volts for nominal speed (not surprising since both are the same process) and in theory both can be over or under clocked and over/under/volted in a similar way.  at nominal 2 th/s just the chips would consume approx 1200-1300 watts, but with dc/dc converter inefficiencies, and controller, and power supply inefficiencies, and cooling systems assume both would consume around 1700-1800 watts for 2TH/s nominal.
3.  coincraft claims use of single atx power supply at 1800 watts, cointerra claims use of twin 1100 watt psus.   cointerra's psus will be in their most efficient operating range of 94% when running at nominal speed - i.e. not run at 100% load, coincraft will be in the psu's worst efficiency when running at full load.  perhaps <87% efficiency.  running cost over 1 year with 8% loss of efficiency is expensive (hundreds of dollars in electrical and cooling costs over a year)
4.  household outlet load.  some household outlets limit power output to 1500 watts.  if trying to draw 1800 watts from one circuit, there's a chance it will be overloaded and trip breakers/fuses or worse. cointerra uses twin power outlets for its twin psus.  irrevelent in a data centre where abundant power is available.
5.  overclocking.  coincraft running 2th nominal at max load for the supplied psu.  extra psu will be needed for overclocking (add $300?  plus some space for it in the rack).  cointerra has extra margin of power for over clocking. (2200 total power available in box)
6.  controller board.  coincraft rig has raspberry pi.  cointerra has beaglebone black.  latter is more powerful. not sure if that makes a difference but 2 TH is a lot of hashing performance the controller has to keep busy.  even a 550 gh/s kncminer uses a beaglebone black so bitmine may have underpowered the controller.  tbd.
5.  cooling.  1800 watts is a LOT of cooling requirement.  cointerra is using liquid cooling, and coincraft is using air.  thats asking a lot of their fans and heatsinks to cool that much heat, so we will see if it works.
6.  january price for 2 TH, coincraft is $12,000, cointerra is $6,000

hope that helps

Yes but not 28nm gear.

All I know is, I want another 2TH ASAP, and not sure which horse to bet on; Coincraft or CoinTerra

Would love to buy more BitFury product (even though it's 55nm), or KNC, but neither appear to be available for purchase/delivery before the new year :/

*grumbles*

Yes, except Bitfury is 55nm.  The OP was asking about 28nm.

done... thanks!

do the math again :-)

since knc has 4 chips in a jupiter and most of them run at 550 gh/s, i think each chip would be quoted at 137 gh/s  (corrected)

and bitfury typical seems to be 2 gh/s
hashfast claims 400 gh/s (and o/c to 500?) in mid december
cointerra claims 500 gh/s (and o/c to ?) in late december

Bitfury is shipping.

Black Arrow says February
Coincraft (Bitmine) says December

VMC... not sure just how legit they are.

Cointerra - maybe January
HashFast - maybe January
ButterflyLabs - maybe February, if ever.
Avalon - Best to forget they even try to exist, may want to apply to BFL also.

BFL really has a chance to turn themselves around, but given their track record and the complete lack of attempts to improve their image, I find it highly unlikely.

EDIT: Would just like to note, OP changed the OP and my post answered a question he had asked about the above companies, and then some.
