 10nm.  

   The first thing is most customers do not know the right questions to ask a mining company to ferret out if they are bullshit or not. So, I encourage everyone to ask the right questions about chips, fabrication,  etc.  If the guy doesnt know what he is talking about it will be clear right away.  

Speculations:  In the beginning a bunch of folks were saying it was a 16nm chip.  And some speculated that it was just
and overclocked S9. Hmm, dunno. The problem with it being a  16nm  chip from a new company is that TSMC would not give a new customer any wafer capicity.

How about  TSMC  10nm?  Well if they answer TSMC  10nm,  then that   fuels another speculation that buzzed around on twitter
that Halong  is  just a Bitmain  subsidary  and  it's Bitmain's method for selling chips. It also helps them clean up their
act  and  diffuse concerns about the concentration in mining. Information vacuums  are never good as they fuel speculation.


Maybe TSMC 12?  performance is somewhat consistent with that.
 
Intel?   Nope.  


Samsung 10nm.   From a performance and shipping standpoint samsung 10nm makes sense because  there is an apparent  yeild issue ( there always is )  and because there is  what looks to be a voltage leak problem which could lead to excessive power consumption. You'll get chips that run at  sub  .09J/GH  and  devices that run above this.  If you can just run the thing through a variety of frequencies and see what happens to the power consumption that will be  a good clue. Maybe they can tweak the  the process to reduce the portion of chips that might have this issue.  Ideally,  they would do  different SKUs,  those that run between 15 and 16 and those that run faster. Hard to do unless you have big volume. In any case  if it is samsung 10nm, then the best thing to do is just to address the performace variations and explain what you are doing to reduce/improve the situation. If they are tweaking the process to run at a fast corner (for example), just tell folks. We are tweaking the process.
If you build chips  it is what you do.

In the end someone somewhere will decap  chip or take it to their dentist for an xray and post the dimensions. I should
do a bounty on that.  If you know the dimensions of the bare die that will tell alot. Has anyone decaped a Bitmain chip?

Finally, the other thing is some guys  use  chip specs  to derive machine specs.  That means you might spec  16TH .07  from
the  single chip performance  ( averages of lots) but when you actually build a machine  its  15-16TH  and  .1  at the wall.
what we do is a little different.  We spec machines  after they are built and tested. So  13TH,  actually means a tested
MINIMUM  13, and empirically  75% of the machines  run at 13.5 or higher.   Ideally there would be some kind of standard
benchmarking  but I dont think the industry is ready for that.

Anyway,  more information from everyone, open information from everyone is always a good thing.

thanks, kinda best post on topic so far

Yeah, god knows I tried with them but they were not interested selling a miner for me to review.
This was back in January or so.

they recently elaborated about this particular issue with T16 units for a demo purpose before start of sales https://halongmining.com/blog/2018/03/07/dragonmint-btc-miner-uses-version-rolling-asicboost/

Max. order is 68000 apparently. Not sure if it is actually the current batch numbers or even a valid quantity. Still, that's amounts to a whole lotta wampum.

That would bring the network hashrate to 143 PH which is exactly 100 times the current. So profitability would be $4-5/day. Of course it would be insane to release 68000 at the same time, not to mention i don't think they have the production capacity. They haven't even shipped a single 16T miner yet..

68000 off first release would be a monumental task, i would think a tenth of that for the first batch.  Will be watching this one from afar but looks like bitmain has a serious competitor if they can produce at mass rates

Exactly, I think anything between 5-10k units too. If they release 10k it would be the exact same situation as with Bitmain's A3 - a few days of $100-200/day if you're one of the first and then gradually settle at $40/day. But the other interesting factor is what will Bitmain's reaction be - there is no way they aren't working on a Decred ASIC too, so I'd expect them to react immediately and release something in the next couple of weeks, even if it's a smaller count than originally planned.

In the end the big loser is of course Obelisk, which got absolutely crushed between these two giants (Halong is still a giant only on paper though).

for your consideration there’s were  5000 A3s in the first batch

are you serious with 68k units?? this is just the max value for the variable to be. try order 68000 pcs and there’s still be stock left.

no one can do a 68000 batch now, maybe samsung or something like that

and here's the website updated just today https://halongmining.com/shop/dragonmint-b29-blake256-miner/
seems that we can expect start of sales anytime soon

I received almost 22k Sia Coins within first 24 hours... diffiuclty level is adjusting and quickly as more countries round world join the mining of SC

would you mind to give us a link on your siamining.com profile
waiting for my 2x A3s coming 29th but the only real stats I saw yet are from that youtube dude on previous page
