just wait for the official release
these are rumors as far as I know

If it is 1200 I am looking at 1600 after shipping and tax.

you are very close at price range
after shipping and taxes it will hit around 2k

I am hearing the same thing.. Huge dud if you ask me.. S9 still has long legs.

Only thing that may make it attractive is price. 1k or less?

But 2k is pretty high price.

I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

S15:
850W wall means 790W DC -> 750W boards -> 710W chips for 0.042J/GH at the chip.
1600W wall means 1470W DC -> 1390W boards -> 1290W chips for 0.046J/GH at the chip

T15:
1200W wall means 1100W DC -> 1030W boards -> 980W chips for .049J/GH at the chip
1540W wall means 1415W DC -> 1330W boards -> 1250W chips for 0.054J/GH at the chip

I buy the T15 numbers, but if the S15 numbers are correct it's a bit of a feat. Not so impressive considering it took them 2.5 years to just beat what Bitfury and M10 are doing with 16nm. I'm mostly impressed that there'd be a sub-KW option.

Maybe  it is worth buying.

Maybe not.

Edited, sorry for the mislabeling. I was paying too much attention to all the other numbers. A sub-KW sub-$k miner would be pretty nice with anywhere near that efficiency.

Buying or not buying might depend on the price and other characteristics.
For example: is lower wattage a different machine (like mini) or is it a different set of frequency.
They actually implemented it (two settings) in some other machines as balanced vs turbo settings.

BTW, is it worth it to do passport/DL KYC with Bitmain and risk losing your creds somewhere in china?
Honestly, i don't get it why we have to do it since they already have our names and addresses?

1500/34000 = too good too be true.

44 watts a th is head and shoulders better then the m10 which is about 68 to 70 watts a th.

But they did claim under 50 watts a th.

Same ballpark as Bitfury's "Clarke" chip.
Bitmain does have a history of getting higher performance out of a node than most of the competition (though Bitfury is usually in the same ballpark).

Innosilicon in particular tends to be lower performance on a given node than Bitmain manages (there are persistant rumors that the Innosilicon A3 was never released because it was no better to worse performance than the chip that Bitmain used in the S7 on an older node).

I'm no longer legendary just in my own mind!

Looks like the official spec is 34th/1600w

Lets see if its true but from my supplier he says this +/- 10%

So they have updates the sales option on the chinese site.

I checked it out and translated just to get there. Here are their numbers

S15

28 TH/S +/-2%   @ 1596W  +/- 7%     states 50 J/TH

Efficiency Mode - I think can't confirm as I can only read the numbers but it still looks like there is only 1 machine option

17  TH/S +/- 2%    @ 850W +/- 7%      states 57 J/TH

*Updating *

T15

23 TH/S  +/-2%  @  1541W  +/- 7%      States 67 J/TH

Efficiency Mode - I think can't confirm as I can only read the numbers but it still looks like there is only 1 machine option

20 TH/S  +/- 2%  @  1200W  +/- 7%     States 60 J/TH

Both include the PSU and have max order quantities 2 for the S and 5 for the T

I belive they are also stating delivery between December 1 - 10. Might just be for China. There may be a price in there as well, but the format it translated to looks funky so I'll leave that out.

Sorry I did not follow your links, as they looked odd to me. I went here by going to their site and then flipping to the China option.

So a dec 1 to dec 12 ship date.

That is not too bad.

And a 50 watt per th

That is good.

I wonder how long they have been mining with this devices, I also know about S11 and T11 which never exposed to public and I've seen the prototypes 2-3 month ago.
Dec shipping isn't that bad and now I'm guessing what will happen.
Oh and as I know first batch quantity will be limited to max

Do I see a control line going into the power supply? I've been wondering for a while, what with all these miners now coming with power supplies built in, if they might be dropping the board-level string regulator and tightening control on the mains supply instead. That removes any opportunity for board-level tuning, as now the entire miner has to ride the required voltage for the weakest single chip, and it also removes the option to ever replace your power supply with something other than their specific build (so you're over a barrel, warranty-wise). If they're binning chips pretty specifically imbalances can be minimized and you end up with around a 3-6% efficiency gain and slightly reduced BOM. That binning might be why they're rolling out both a low-spec and high-spec model at the same time.
Looks like they may also be slacking on the density a bit, or at least starting to shorten the air path which keeps the rearmost chips from getting overcooked. That's a good sign, and a lesson that should have been learned from Spondoolies rack gear in 2014.

You... I guess they nailed it lol.

Missed that post, as it would have been so much easier to just quote and say he nailed it with a link. Nice when at the end you can trust a good source.

[...]

Yeah the S model numbers look awesome. They are definitely trying to regain the king of the mountain spot with efficiency. The price will be interesting. Depending on what rumors to believe are they going to try and grab as much Bcash/Fiat as possible quickly. Do they look to maximize profit, not worry about how fast the product moves(probably not an issue with the specs).

I updated that post as well, once I saw what looked like Delivery between Dec 1 - 10. Only being 3 to 4 weeks out is better than I thought. I expected end of Dec/early Jan.

That removes any opportunity for board-level tuning, as now the entire miner has to ride the required voltage for the weakest single chip, and it also removes the option to ever replace your power supply with something other than their specific build (so you're over a barrel, warranty-wise).

This has always been my worry about buying a unit/PSU combo. Now you've given me a logical reason for that. Obviously without a closer look we don't know if that's for sure the case, but I don't have a decent option to warranty with them. So losing the unit over a dead PSU, would be a piss off.
