Topic: Bitmain Antminer S6 and S7 Speculation - page 7. (Read 33492 times)

The S4 is actually my favorite size/shape for a rackable miner. It's well-proportioned compared to a lot of things, especially like Spondoolies gear. I'd welcome another miner in that form factor - a better miner than an S4+ anyways. If they used the same size boards/modules as in the S4 and S4+ with, say, a 5x17 string of BM1384 instead of 3x17 BM1382 they could have done 4.2TH in the same size box off the same PSU. If they come up with a new chip 20-30% better those numbers would still be possible with fewer chips and a higher clock.

Something small in the S[odd] form-factor to replace S5 would certainly be nice. Maybe back down around the 400W range instead of 550, keep it a bit quieter. A chip 20% better than BM1384 in a 2x16 string could see the same ~1150GH off less than 400W from the wall. If you want S5 power level, a 3x16 string would run you 1.7TH off 600W wall.

This is assuming the same V/F curves as a BM1384, with 80% the J/GH.

so no new specs for s6 yet, it was supposed to come out this months? are we really talking about julòy 31?

i hope it isn't something too bulky like the s4, i prefer cheap miners with very good efficiency, maybe i can jump again on the whole mining thing

If your coin isn't protected by ASIC's it is useless as any country can just smash it at will with a super computer if it ever becomes a fraction of a threat.

Yeah I think you are spot on with this.  the S2 was supposed to be the answer to everything.  Being able to have the boards on a backplane was a good selling point for them and the apparent upgrade path was promising.  too bad they never really cared to follow through.

But "whatever is the most profitable" at any given moment is based pretty heavily on everyone else's speculation, manipulation and lies. With very few exceptions, altcoin mining is a zero-sum game where the only winner comes out ahead at the expense of everyone else whose timing was not quite as good.

I do agree a modular miner is necessary. S2 should be that, if Bitmain (or someone else) decides to make use of that framework. The stuff I'm working on could become a solution, but there are a lot of "if" to it.

Since the altcoin economy is somehow less shady...

Wasn't the design of the S2 supposed to be that modular machine?  A bunch of boards on a backplane that could easily be swapped out.  Unfortunately, they (Bitmain) never followed through with any upgrade kits.  That kind of setup would be great for the datacenter guys.  Keep the chassis and just upgrade the boards.

No that was merely temporary while they raised prices on it from 399 to 414 plus shipping.

They have no reason to sell s-7's at this moment.  The current pricing is working and they will continue to do this as long as they can.

Bitmain's site is now claiming to be out of Batch 5 on the S5. I suspect they now have incentive to get around to releasing whatever is next, since they appear to have managed to clean out their old stuff despite their price gouging price raises this month.

 (edit) Never mind, it seems to be temporarily "out of stock" when they're adjusting the amount of price gouge. It's been bouncing in and out for a few days now.

If they keep going with the unregulated string option (which does offer the best efficiency and cost) it'll always run at a fixed operating point, which for chip cost reasons they'll always set near the top of the chip's practical limits. They could make a 0.38W/GH wall 1.4TH miner in the S[odd] chassis with existing chips if they wanted to, but the chip cost would be about twice that of the S5. I was surprised they didn't do something like that for a rackable miner, instead going with BM1382 for the S4+ (where the BM1384 could have given 4TH off the same power consumption and the same basic design). Maybe they'll put out an S6 with BM1384 in a high-density string and an S7 with the new chip, and charge a premium for both because they're both pretty good gear.

I'm hoping for a new chip.   Your thread has surprised me at what the current chip can do.   They really could make a next gen and make it more efficient.

Anything in low .3W/GH would be nice.   Maybe a underclock option to get in high .2W/GH would be even nicer.

A 2x16 string on the S5 instead of a 2x15 would have made it a 1TH miner at 0.43W/GH wall. I'm assuming they'll have a new chip that does better than that. I'm rooting for board-level top clock at or below 0.32W/GH, but that's not based on anything just what I'd like to see.

Be interesting to see what the s-7 does vs the s-5. 

will .52 watts per gh drop to .35 watts per gh.

My guess is .38-.41 watts per gh for the s-7

Yeah, there is still quite a bit of July left. Bitmain likes to announce a couple weeks before they actually start shipping, but a July announcement for an early August miner would still be okay.

I think it was a ""end of July miner"" from Bitmain
 

So, a July miner from Bitmain hasn't happened so far.

Www.bitcoinbrothers.de

Winter is comming! August 1

It is great to read all of your opinions on manufacturers especially when talking efficiency.

A point a couple of you made had me down a rabbit-hole of thoughts regarding the present and future of mining. So much that if you have the time I would enjoy appreciate understanding more about is the fact the S3 (S3+ or ++ most never saw, much less touched) was better built than the latest offering, the S5. Dual fans, metal case, routed airflow, ran much cooler and the S5 with plastic sides, no top, and no bottom, along with more speculation. It is probably unusual speculation, but I think has a real question.

More specifically to my area of curiosity is those of you who have been around and had hands on with every bitmain product available to you S1, S2, S3, S4, S5, USB models matter, what is your opinion regarding the next version of hardware?
point 1: which must already be running / being tested or 'burned in' by BITMAIN... today, correct or not and why?; has every model been burned in? How long do you think they are 'burned in'? I understand it takes some testing to feel good about a product shipping and I am curious.
B: How much market share does bitmain have versus bitfury including any speculation or known facts regarding other ventures, ie pools, private mines, trading, or any category you feel is applicable. Another side of this is simply of all the miners in the field today and 1 year from today, what are the numbers, your guesses please.
3: If, now seriously, if, there ever is a hashpower war / attack, or whatever you want to call it, (entertain the worst possible scenario from Mike Hearn regarding the money side of bitcoin facing off the hashing side of bitcoin) far out speculation like the bitcoin network is being attacked by the reptilian overlords from the future who use humans for cloning experiments and gambling...
...how much literal hashpower / which pools, people, companies, etc would have to collude hashpower to impact the network in the most-likely way? Could Bitfury do it, KNC, BITMAIN, F2pool and BITMAIN, how much hashpower does it take today assuming you have the knowledge? It has very much surprised me to hear how large the bitcoin network is in terms of hashing power and look at a mining pool chart and see so much hashing power controlled by so few people. How much hash could be held by the fewest number of poeople or could we ever see it all owned by one company? 
A for example on this one is say, Discus Fish / F2POOL and Kano.IS were being 'mind-controlled' by those future lizards and the lizards can only impact the people owning / running these two pools, what could they do with current gen, and do they have anything on the workbench of R&D lab which could own the bitcoin network in a negative, or positive way, and what is that way?


 

With all due respect, it's kinda hard not to laugh when "Lack of Bankruptcy" make a company worthy of serious consideration. 

Probably need to work on a new lexicon for Bitcoin mining:

New means "Not previously sold by the manufacturer and comes with a Warranty"

Doing Well means "Hasn't filed for Bankruptcy (Yet)"

I assume by "New", they mean "Well tested for the last 3 months"? I guess the $420 price is in line with what I hear is a recent Bitmain price increase for the S5 (to $378).

Is this an odd way to "clear inventory" before a new product comes out? Usually a company will discount an older product prior to the introduction of a newer product (e.g. the S7).
