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.

so two speeds.

If it does 850/17000 on slow that is 50 watts a th.

But 2k is pretty high price.

agree, but first batch will sold out in minuts and plus they are altering BCH price

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?

Any source for this info ?

How legit is it.

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 doubt the S15/T15 can get 34TH at 1500W. GMO has their 7nm chips out and their Miner B3 unit is 81W per T. A lot of the power efficiency and how well it performs comes down to chip design. We know that Bitmain is bleeding money and they lost most of their best engineers. If their ASIC really was as awesome as they claim it is, they would have released some real numbers on their "teaser" release. So the only thing really they could hype about is the 7nm technology. If their chips really did 45W per T, they would have bragged about it already. Just my 2 cents.

The whatsminer m10 does 34th at about 2400watts. I have two of them. And they use a 16nm chip.

So I get around 68-70 watts a th with them.

I think we will get 55-62 watts th with this gear.

The real concern is how fast do they ship it.

We are not retail.

In a few hours we'll know more. Just wondering how much.

Some leaked info Grin

Hashrate =34TH
Price = 1200
power = 1500W

these information was giving to me by a Chinese friend who is an loyal customer of bitmain. I can not confirm/deny but usually his leaks are accurate. let's find out in 2 days.

It will take a while for the 7/10nm generation miner makers to make enough miners to push the difficulty up to the point the S9 becomes unprofitable if you have VERY cheap electric - but that point will get reached eventually.

And if it goes on sale on nov 8 I hope it ships quickly.

Not sure it is worth 1600 unless it comes really fast and does 55 watts not 65 watts

I'm pretty sure they will be more than 1200 stock + shipping and taxes in some cases

As an electronics builder in a family of beef and soybean farmers, I get to see the tariff double-whammy up close. China's retaliatory tariffs on us are for products they can buy from at least 20 other countries. But our best tariffs on China are for products the entire planet (led by us) has, over the last 30 years, tacitly handed complete control of to them without any concerns whatsoever. Has China's export business even noticed a dip?

Yeah, these additional 25% tariffs are definitely killing us miners here in the US. Quite frustrating.

The best a s7 with lots of mods was around 0.22 or 220 watts a th

The s9j can do about 88 watts a th

On a chip rated about 0.068 watt a th.

Bitfury 100 watt a th gear

Can go as low as .06 watts a th.

So a .042 watt chip

Is going to be more like 55 watts maybe 60 watts a th.

I just wish two things a manual speed not auto tune.

As I prefer slight underclock.

And if it goes on sale on nov 8 I hope it ships quickly.

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

Picture also hints at integrated psu and dual fans one side. So quad fan?

We should be able to rule out their need to use the APW7 for this.

Thinking 35- 40th/s at 2500w perhaps? (high end)

It appears to be lessor in depth also, they have probably realized that shorter hash boards will have better cooling performance.

I think he is off. If the Watt draw was that low, why did Bitmain release a 1800 watt PSU? My guess is 32 Th/s pulling 1600 watts ATW.

i do tihnk he may be off in hashrate aspect, but as for power cons i think you are off, i am guessing 1400 or less , you know bitmain needs to target people who have only 100-140 volts too. and i do not think bitmain has any sort of psu that can supply anything above 1500w for those people. and ofcourse they would want to sell their psus as well !.

but still we are all just speculating here, the real numbers will be there in 2 days.
