Topic: Bitmain Antminer S6 and S7 Speculation - page 5. (Read 33553 times)

 Common short term variation. Don't look at instantanious hash rates, look at a longer-term average like on bitcoinwisdom. Short spikes ALWAYS happen, and sometimes they're pretty big.

Right, but i am saying, they can replenish their stock with S5s they currently run in their mines and maybe some they have in storage. And they sure do have a lot of them.

Since they can simply power down a section of the miner and refurbish the S5's they can effectively replenish the stock at any time.

Hmm luck affect the guessed network hashrate too, i wouldn't go saying Bitmain went and offlined 100PH in a shot. It's not 296 today either, look more like 360. But its possible they onlined a bunch of hardware yesterday and offlined a batch of S5 today to be ready to ship for the 14th+ august date.

I find the up spike and then down spike exactly syncing with bitmain's S5 event days pretty funny. And maybe suggest that Bitmain is truly doing what everything think they are doing...


They can replenish the stock at anytime, too.

Price: 440.0 USD(1.55783314฿)  Stock: 177

Slowly getting to 0.

Noon yesterday net hashrate was 413 and today it's 296.  Is the big swing from Bitmain, KnC or the hot weather?

Diff isn't just about the S7.

 It's also about KnC "Solar", which was announced to be "in production" a while ago, though in unknown quantity.
 It's about whatever BitFury is selling to their big farm customers - again, no hard data but I remember a MBP posting about "next gen" a while back.
 It's about whoever bought most of that first batch of Sfards machines to a small degree.
 It's also going to be about the Innosilicon A3 and products built from that when it is released.
 It might end up being in part about other manufacturers that haven't made any sort of announcements to date.



 I'm betting we'll see the S7 specs announced about the same time that BitMain makes their "final" batch of used S5s available for sale, and the machine itself will go on sale about the same time the last of those used S5s get sold off.


 As to WHEN that will be, dunno. Hoping for early September but not holding my breath....

I get the feeling late October maybe Nov. before the s-7 sells as for higher diff jumps  like 4 and 6 % also not going to happen that easy.

Basically cheap power trumps better asics.

a 3 cent farm with used s-3's  crushes a 6 cent farm with new  s-5's do the math.  for a 4ph farm of  of each.

unless the s-7 jumps to .1 watts massive diff rates will not happen.

Yeah, i don't know if they planned on gradually selling all their S5 but if their farm size is any indication of how many S5(but also maybe S4/+) there may be, they could tally up the used S5 for sale from many hundred to some low thousands.

Agreed. I'll ping them again in a few weeks. Hashnest is down to 210 S5's.. maybe they'll announce something when it's down to 0. Or I guess they can just replenish it with more used inventory.

That's good, there's no point in debating the legitimacy of this. It did get reported several time already by trusted member.

Now if only "May(be) in 1 or 2 months we might be releasing S7" was just a little bit less vague and included some technical specs we could start extrapolating values. xD

Hi,
No details yet, new product may be released in one or two months later, we don't have the exact info yet.
Please pay attention to our official announcement or update in website.
Thanks.

Hi,
S7 will be released in July, but we don't have the detailed info yet.
Please wait for our official announcement later.

It is good to have additional input. However i'd kind of like to read it from Bitmain. It's just hard to warrant putting money on that probable fact since in the end, there's no guarantee that they will be announcing a new unit that will be ready to ship in the immediate or near future.
There's no guarantee it will be indeed in another 2-6 weeks that Bitmain will give us an announcement in the first place... or that it will lead to a shift in ASIC value.

Bitmaintech has mentioned to several people (including myself) that the next unit coming is the S7. There can certainly be an S6 down the road, but I'd imagine the next one out will be the S7 as they keep saying. Their original ETA was to make the announcement in July, but last I spoke to them (2 weeks ago) they said to wait another month (or maybe even 2).

I am pretty sure he is just jesting. The water cool serie is C, not S in the first place. There's also rumors(not sure if the confirmation is true) of the S6 being skipped altogether. Seem logical with the recent S4+, anyways.
This is a speculation thread, he was probably just voicing his Christmas wishes.

where did you get that information? link?

 

any confirmation on this?

thx!

That sound like wishful thinking to me =/

There's little incentive for them to develop(or sell) such effective miners. Truth be told, a jump from .5 to .29 or less stock is pretty big and probably expensive to develop versus the alternative.
There's sure to be a gain in efficiency over the "last generation" but the big ASIC market demand is to miners with cheap electricity. Big datacenter located in China and other few places in the world where electricity is 4cents~/kwh. Then a smaller demand from smaller miners with also cheap electricity. And then a even smaller demand from smaller miners with no so cheap electricity (8+ cents).

So all in all, maybe we'll get a expensive unit with high efficiency, but i wouldn't bet on it, since its not that lucrative for Bitmain anymore.

There have been comments (by Dogie I think, or someone from Bitmain itself) that they are going to skip the S6 and go straight to an S7. In any case, if they came out with another water-cooled rig it would be probably be called the "C3" in keeping with their current naming progression.


 Buying an S5 and needed power supply right now is VERY VERY IIFY on ROI unless you have 5 cent/KWH or cheaper power. The size of difficulty increase is going up since all of the "next gen" announcements to date, and looks likely to go up faster for a few months or a bit longer than it did the first half of this year, with the widespread adoption of "next gen" mining gear in the big mining farms as the gear becomes available.


 I'm hoping for an S7 that does over 2TH for under 600 watts and $600 or less, otherwise ROI is going to be very iffy even WITH cheap electric due to the bitcoin halfing next summer (unless bitcoin climbs a LOT somewhere between now and then, or the current rate of difficulty increase drops by at least half of the last couple of incriments for the next year). I'm also hoping that Bitmain goes back to making the voltage adjustable, rather than the S5's "chained power" setup - that would be worth an extra $100 easy, as you could undervolt later on and keep the mining profitable for a lot longer or at higher power costs (an SP20E can be profitable at 18 cents/kwh if you undervolt it enough, an S5 right now loses money at that power cost with current difficulty and bitcoin pricing).

 2TH at 400 watts or 3Th at 600, might be able to sell as high as $800 and still manage to ROI at some point, but I suspect Bitmain is going to release the S7 with a chained-power design at or very close to the highest rated voltage the chip can handle (just like the S5) at the cost of efficiency and somewhat of a loss of long-term ROI ability.

 What I'd LIKE to see is an "S5 Lite" model, still using the BM1384 but chaining 18 chips - should run about 800Mh/s at less than 350 watts - in the $400 range. THAT would ROI no problem, and still be profitable after the halving for quite a while even if Bitcoin price stays flat and difficulty increases stay in the RECENT 2-3% on average range.

S6 is water cooled 4.4 TH machine with 2200 Watt PSU.They will release it as soon as they melt down their S5 stocks.

And yes, S5 will do good profit from now on to the release.

The "having been run professionally 24/7" is better than run sometimes for the same period because the cool down and warm up are more likely to see damage than steady running.
