Interesting rumors on imminent introduction of antminer S7 'lite" hashing at 3.5 Th
Speculate on price...
My take: ~3.5 BTC initially ($1000), eventually down to 3 BTC.

Here's a repeat on my speculation as to how they achieve 3.5TH


Very interesting and a very big drop.The OP indicates a reduction in the number of chips and the simplest way to get it would be to go for a 2 Board version?

However to get 3.5TH from 2 of the current Boards you would need to run at 650MHz to give 3510TH which given the underclocked releases we have seen from 600MHz to 575MHz & 550MHz could be a problem?

650MHz is within the capability of the chip however the core voltage would be a little low for that hash rate. So if 2 boards I think they might need to change the number of chips on the boards?

The above does not quite adds up so perhaps the other approach would be to depopulate the boards reducing each from 18 tripples to 18 doubles. So total chips from 162 to 108? However unless you up the clock rate you still fall a bit short of 3.5TH, but in either scheme 3.1TH - 3.2TH  would work. We will have to wait & see.  Smiley


On the price I think they will want to head off the B-Eleven which I think we will see for a one off price of 3BTC, $850. So  given that they will beat BW.com to market with a 3TH Miner I think that Biodom is on the money.  Smiley

Here's where I read it.

New s7 information
bitmain told me that new s7 will be released to market after another 10 days, so should be on 10th Nov, they deduce the chip amount on s7, so the hashrate of new s7 will be only around 3.5T. The price for new s7 still under discussion and will be released next week

Lee is a major hoster in China so he gets okay info.

I mine alt coins with https://simplemining.net...
I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

i also doubt that he would have posted that without permission; it looked like an approved info leak.

Thanks much appreciated. I wonder when released if the price would cause S7 price on Hashnest to tank. I have been waiting to buy S7 but not at the current premium demanded by sellers.

I don't know on this.  If you read any NDA is this game this is covered as info you cannot give out.  I would be very surprised if it was approved.

Is there any reason on him leaking is he out of current S7's?  I'm guessing his info is ok as-well but I think there was a bushiness reason he released it now with a timeline when no one else has said a peep.

I just cannot see a "approved leak".  I do like that the info came out but he is braver then I for leaking and chances are having a NDA with them.

Au contraire, i can easily see that. In fact, their competition (BW) just posted an interview where they claimed 0.87BTC/Th (or even per the 3.3 TH machine, which i think was a misquote as the price difference would be too big) for 1ph orders. Leaking some info without an official announcement is a perfect way to reduce the competitor hype without truly committing to any hard numbers. A trial baloon, if you will, aimed to reduce the competitors pre-orders (which are actually going on right now until Nov 11).
Besides, leaking now is harmless with regards to the current situation as there are no miners to purchase.

I always think most actions have a reason behind them.  If you look now the "source" bought 3PH he say's in avalon and want's to sell cloud mining

https://bitcointalk.org/index.php?topic=934581.msg12777226#msg12777226

So I suspect in coming day's there is a order he will do on cloud, and try to push antminer to a 2nd in sales compared to his cloud.   Which if you read he does not want to part out as he say's a RPI can control 60 units.

But we all know a RPI can be bought for 35 bucks and they could easily be parted.  So ... look at it on day's coming and you will see reason.  I mean it works out good for us since we got likely good info, but always a reason.

Edit noticed he said they ship on "31th Oct" so that gives him a shot at selling cloud before the Nov 10 date he said on the bitmain new S7.   So likely we will see a push for sales of the cloud during that time period.

if that would be really the price, it would be very good with 900w consumption, and only half of the investment of his big brother, bu still with 3/4 of the power

i think they can still release another version with half the power and 1/3 of the cost

Two chips per node instead of three would require a new PCB, not just not populating those chips. BM1385 relay comms from one chip to the next so leaving out a single chip would disable every chip downstream from it - which in a string configuration means current ceases to flow in the circuit so even the first chips which are getting work data are starved for power and do not work.

Regarding Avalon, if the 6 works like the 4.1, it would suck to part them out because the machines are actually daisy-chained on an SPI bus. About every dozen machines or so (I forget the exact numbers) will be on a common bus to a USB adapter to the Pi. Parting out individual machines would mean having to stock additional USB adapters and such, and having to verify with the customer what the installation would be and how many accessory parts would be needed to get them all talking. It's not as simple as just tossing in an additional Pi.

Agreed. The "obvious" way to get 3.5TH is as I said above.

650MHz is within the capability of the chip however the core voltage would be a little low for that hash rate. So if 2 boards I think they might need to change the number of chips on the boards?


My concern is as stated. The 2 chips / node did not solve the problem either. I was just think typing  Smiley

If it's nice and balanced speed vs noise, then ok!

Otherwise give me s7++

I doubt noise is a factor on it.  I'm hoping they keep a full case design even though it's a little higher.

My biggest fear is to see something like S5 with two blade in a plastic sided no full case device.  Not sure what to expect on the new version.

Honestly, nobody knows how accurate this is, hence it is 'rumors" in "speculation" rubric, NOT in hardware.

As a source it should be pretty accurate.  If he truly was in a town purchasing 3PH of power I'm sure he would have talked to bitmain and avalon as it sounds he did.

The date of Nov 10th was thrown around so guess we just have to wait to see if Bitmain really did make such a big move.  I suspect from reading thread he has avalon cloud he talks about for sell before this Nov 10th date.   But guess we will have to wait and see.

Honestly I believe it as it would push a lot of chips and units and it is something the home miners want, would love to see this and the avalon release (and possibly the bw miner), going to be a great generation!

Any point for this miner will be to be quiet! other wise.... i don't really care Smiley
