We have recently released a new video demonstrating a working FGPA, as well as additional GoldStrike1 ASIC chip details.

To watch the video and read the full release, please head to http://cointerra.com/cointerra-demonstrates-working-fpga-releases-additional-chip-details/ .


If you can't wait and just want the GoldStrike ASIC specs, here they are!

Global Foundries: 28nm HPP process.Clock-speed: 1.4 GHz (min binning speed) to 2 GHz (max binning speed)

Die size: 3 dies of 10x10 nm for a total of 300 sqmm.

Hash rate: 504 GH/s to 720 GH/s based on binning speed

Hashes per sq mm: 1.67 GH/s/mm2 to 2.34 GH/s/mm2

Power consumption: <0.6 watts/GH/s (@ 0.765 volts)

Architecture: pipelined unrolled hashing units

Tape-out due: 1st week of October

System cooling:  Custom designed liquid cooling by CoolIT Systems capable of 400 watts per chip, though the chip will not exceed 300 watts in normal operating condition. incorporating  3x high speed 12cm fans with 4U sized radiator at the back.  System box was recently upgraded from 2u to 4u to allow for larger fans and radiator to provide significant increase in cooling capacity and reduced fan noise  - 12cm fans are much quieter than 9cm fans.

Logistics: By design, all suppliers (excluding ASIC), including PCB design, board and box assembly provided locally in Austin to reduce shipping delays of parts between locations and eliminate delays due to logistics or customs.

Significant payments made to fab to expedite process from usual 90+ days to 65 days.

Chips expected back, early December.

Systems expected to begin shipping to customers, Mid December.

Boss da chips da chips... are they for sale?

any plan to offer hosting?

500ghs will be so sslow by that time

going from a working FPGA to an ASIC isnt a simple task.....    I'd save the bragging for when you have a functional prototype.....


just my 2 cents

Awesome news, I look forward to having some of these hosted at my facility.
As A native texan , are you guys ok with organized ahead of time visits?

Yes, you are always welcome to visit us in Austin! :)

If you just got the FPGA to work, how can you complete the back-end trial-run, back-end final-run and functional verification in 1 week?

The screenshot in the video shows solo-mining on the testnet. The first block created there was block #106507 at Thu, 19 Sep 2013 14:52:32 GMT. We also mined on eligius (statistics at http://eligius.st/~wizkid057/newstats/userstats.php/1P17UueqcMDw2P8FWv8Ny4ryGopicQmJPN).

Shot yall a PM :)

Did no one actually read this? The chips don't even exist yet and the spec rollbacks are already happening. Now takes 2x the space.

I would prefer better cooling to a smaller case if given a choice.

How is that a spec rollback?

Still no response.

If someone was looking to rent an entire datacenter rack.  They would get 25.2 TH per rack using HF and "only" 20 TH per rack using Cointerra.  The older spec would have been 42 TH per rack.

Generally hosting is charged by the KW and not by the space it consumes so ther would be no difference in cost for requiring more rack space

Also the more important Criteria is cooling. Generally there is a limit of 8-10 kW per rack and usually it's less than 10 KW per rack. Few data centers allow more. Thus you will be sparsely populating these Bitcoin mining equipment on the racks with plenty of air in between regardless of 2U or 4U box size so in practice it would take the same amount of rack apace regardless of box size. And cooling these power hungry chips is very important cos they're temperature sensitive and run faster when they're cooler.
