What I am sure is they are open to sell the chips, and they are chips designers, probably is most cost efficient and get faster time to market if we find a way to use just their chips.

burnin will design the PCB for the CoinTerra chip, but I doubt that he will be offering an assembly service to the public.

Aero, I agree 100% with you in theory, but I am not an expert.

I will love to design a PCB and a Case to place Cointerra chips I have the feeling the company will have faster the chips than the untis.

But I need expert advice on this.

All the best

Why do you think the Cointerra chips would be a mess to work with?   Surely, with so much performance in a small space, the design of boards will be much simpler and the number of boards required will be drastically reduced.

to get 0.5 TH - instead of a huge box full of boards with a thousand avalon chips, with complicated interconnects between them and huge power supplies... you could have a single cointerra chip that replaces the 1000 avalon chips, to get similar performance, right?

and its potentially easier to cool one big chip than to cool a thousand smaller chips, because there's a good market in cooling technology for big hot chips that intel, amd, nvidia have been keeping busy.

its probably easier to cool a big hot chip than to cool 1000 small chips because the heat is localised and creates a perfect use case of a big heatsink/fan or an off the shelf water cooling solution similar to what millions of PCs have in them.

KNC, Hashfast and Cointerra seem to be making good use of PC standard cooling components to keep their chips cool.   An Intel or AMD cpu thats been overclocked and overvolted could easily reach 200-300 watts, and these high end pc coolers are fully capable of extracting that heat to the outside of the case.

and doing a board that has multiple big hot chips is similarly easy, just replicate the localised cooling solution you used on one chip, on the other chips as well.  if you have to have four big heatsink/fans in there (like KNC) thats no problem... you could even have four big hot chips cooled by water (either individually, or linked together in the same loop) as such water cooling solutions are off the shelf and very effective.

I know is probably a complex job, but considering 1/2 Tera of each chip, you need like 125 of other chips to have similar performance, may be to use 1 Cointera chip is cheaper than 125 of others.

I may be wrong.

Have they released any specs beyond "28nm feature size"?

Are the die area, package type, core voltage, and TDP known?

I might be wrong, but these are not avalon chips.
They are a mess, 0.5 TH each. They will be a mess to work with. You should just buy the whole package from cointerra.

Hello,

I am not an expert in PCB at all.

I wish to know if someone can design the boards for the Cointerra CHIP.

I wish to build some units with their chips but need help.
