I think they are only selling big order to large private farms right now they have the technology edge for the moment and they are exploiting it

Their chips are having huge yield issues, I doubt they have sold any apart from the couple they made from their sample chips. The whole "batch 1 sold out" is a marketing gimmick.

Yeah hopefully they will fix their chips and mass produce them with a low failure rate and start pumping out miners and have the price drop.

Not a matter of "fixing their chips".
The 16/14nm chip process node itself is the problem for EVERYONE going to those sizes regardless of what the chips are used for. Intel, nVidia, Samsung et al ALL have the same poor yield issues because the manufacturing process is still far from stable.

This simple fact is why Bitmain took the safer route to just optimize their 28nm chips vs rolling the dice on the smaller nodes. Give another year or so and yields for 16/14nm *should* get better. Of course researchers/devs at the chip foundries have been saying that for a couple years now...

I am confused are you saying there are two parts of these chips that are both 14nm making it 28nm, because these are 28nm chips, I wasn't aware that is how they worked.

whoopsy

got thread confused with the LK groups one... https://bitcointalk.org/index.php?topic=1033676.msg12324684#msg12324684 you be right - these are touted as 28nm process, questions then would be is it 2 28nm process dies per-chip or one big one.

On the correct note... 28nm node is stable and easy enough to be good for even some commodity-level quantities. If there is chip problems then highly doubt is is in the mfg end unless they contracted with a company in India (2 20nm fabs, better at 28nm, opened there in the last couple years) or something like that...
