still too big for my taste, it's only 1/4 less bigger, they should aim for 1/2 at least

for those that can't run a big miner in their home, and want to do only occasional mining activity

Doubt there's much profit available for them in a single hash board miner. Still gotta have a frame, controller, and fan - and that would make it very difficult to impossible for them to keep the price/TH competative.

It would actually be 1/3'd less presuming the "2 hash board of current design instead of 3" concept is what they pick.

"integrate the PSU" is not a good idea, way too many variations on size for PS used to power miners.

I suspect folks wanting a "small" miner are going to have to wait for whatever comes out of the Gekkoscience projects - and hopefully SOMEONE will start being willing to sell them chips on a reasonable basis soon in current-gen chips.

If the price was right I think it's a great size. If you compare with 2 x S5 that I run at the moment, you can go from 2.3GH/s for 1180W to 3.5GH/s for 850W in half the space. You can't ask better than that.

Although I guess they could do a single board one, perhaps integrate the PSU where the second board is and have 1.6GH/s for 425W?

I will stick with my original and the most obvious thought that they go from 3 boards to 2. No new design or testing needed, parts are common across all S7 variants and a significant cost reduction.

The only "problem" with this was that the maths did not add up to 3.5TH unless you clocked at 650MHz which given the problems they seem to have had at 600MHz seemed unlikely.

So my best current guess is that the 3.5TH rumour is slightly off and that it will be a 2 Board 3.1TH - 3.2TH S7 lite.

Rich

I would be totally fine with that, especially at a good price!

Me too. the S7 is just out of reach for me so something a touch smaller would be perfect

still too big for my taste, it's only 1/4 less bigger, they should aim for 1/2 at least

I'm not worried about the size. But if they can make one out of 2 blades for cheaper and make it better price per hash... i will be a fan.

I want as much hash as I can get for my money. Guess we see what we really get. It is interesting all this happened after kinda leak of avalon 6.

The only "problem" with this was that the maths did not add up to 3.5TH unless you clocked at 650MHz, at which point V Core would be a bit low and given the problems they seem to have had at 600MHz seemed unlikely.

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.

Should be a way for Bitmain to bypass 1 or 2 chips on the circuit board per string, might need a small amount of glue logic in addition to required jumpers at worst, so they can run a couple chips less per string, run 2 boards instead of 3, and get 3.5TH out of the existing board design.

Or they could just aim at 3.2 TH with 2 of the existing boards.

I suspect the November 10 date is related to when Avalon plans to release the 6 - perhaps Bitmain feels the need to preempt upcomming competiton?

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!

This assertion seems reasonable.

I like the comparison.

the lost generation: s1-s5, Sp10-30, av up to 4.1, asicminer (RIP), cointerra (RIP), knc (withdrew from selling)
the greatest generation-S7, bw?, av6 plus gekkoscience's sticks/pods
the silent generation-SP50?
baby boomers-will come after the halving, will be vast in numbers if price cooperates and employ improved 14/16nm for up to 0.05-0.07J/Gh. Network>1exahash.

bitfury is omnipresent, but invisible. I would call it "dark matter" or "dark energy" Grin

My biggest fear is to see something like S5 with two blade in a plastic sided no full case device.

I will LOL so badly!

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

Do we have any sources on this rumor. I have people that also would like this to be confirmed or denied.

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.

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.

Two chips per node instead of three would require a new PCB, not just not populating those chips.

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

Quote

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?

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

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.

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

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

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

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://bitcointalksearch.org/topic/m.12777226

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.
