Antminer Batches?

[alh]

Batch 6 WILL be worse efficiency, as they're running it at a higher voltage. My best guess is more like 0.3W/GH vs the 0.25 spec on the earlier batches.

Do we actually know they're using shorter chains in this smaller one?

Actually I think we do know. My understanding is that Bitmain has stated that there will be a total of 135 chips for the miner. That works out to 45 chips/board, and then 15 chips per "string/chain". I guess it's possible that there is some other arrangement that yields 135, but hard to see what it would be. The specs for Batch #6 aren't really internally consistent with the other batches, so some of it is guesswork, but educated if you use a little match.

in my opinion, it is a lot 7 bankruptcy, low power and high price

[marvykkio]

S7 power 4.86 th / s = $ 1,658?
s7 power 4,05 th / s = $ 1,518?

We talk less chip, less power, less costs

We don't absolutely know as as far as I know there is not yet a picture and noone has one. However we do know that there are 135 Chips in total, so that has to be 3 boards of 45 Chips each. So assuming we still have a string design then the only maths that works to get the voltage in the correct range is 15 Nodes of 3 Chips.

The interesting unknown for me is if all future S7 will be 135 Chip or if there will still be a 162 Chip System. My money is on them all being 135 Chip

S7 4.05 TH / s = $1,340 just now.  Considerably less $/THs than B5 now.  That's what happens when you keep your eyes open and your mouth shut.

And when Bitmain pegs the price to BTC rather than $$$, and then the price of BTC falls.

[QuintLeo]

It's now lower, but if B5 was still available it would ALSO be lower.

 Probably.

 Not really fair to compare a product that is currently "out of stock" (possible short-term for price adjustment) to one that looks like it will never come back anyway.

Their prices are tied to BTC/USD based on their choice of Chinese exchanges.  Use your brain and post an average rate if you want to appear as if you know what you're talking about.

And why would I posts an average rate, when nobody buys at the average? That figure was exactly what I said it was, a spot price.  BMT has sold gear tied to either BTC or USD in recent batches. My point is you can save money by taking advantage of the exchange, I ended up buying 2x B6 @ $307 exchange, or $1,230 each. Why would I (or anyone) give a fuck what the average was?  B6 has been closed for days now anyways, so it is completely irrelevant until a new batch comes online.

Go back to your bridge now and find some cardboard, winter is coming...

Edit: Tupsu, these were my prices.

ANTMINER S7 BATCH 6
$1269.95 each with shipping, $0.31/GHs paid by WIRE

ANTMINER S7 BATCH 5
BTC4.18 each with shipping, Paid by BTC

ANTMINER S7 BATCH 1
BTC7.9 each with shipping, Paid by BTC

My point again, was that when BMT indexes price to BTC, buy for fiat when BTC is low.  When they fix it to $USD, buy with BTC when BTC is high.  Other than my B1 miners, I am very confident in my S7's ability to ROI before the halving, where they should still be profitable without even accounting for increased BTC value.
