Topic: Every which period of time bitmain release a new miner ? (Read 751 times)

 Nope.
 Their efficiency is almost EXACTLY what the old S7 managed - though the S7 WAS a major improvement over the S5 or even the Spondoolies SP20e running at "efficient" chip voltage.

 Bitmain went DIRECTLY to "make it efficient" on the 14/16nm node - they had the Innosilicon A3 (that never ended up shipping apparently because it WASN'T much if any more efficient than the S7) and the first-generation BW.COM SHA256 miners to compete with that were announced products by the time the S9 first shipped, and BitFury had already demoed their 14/16nm chip with BETTER efficiency (at it's most efficient but low hashrate operating point) than the S9 ever managed.

 Even with the improvements GF TSMC and Samsung have made to their processes since then, I doubt there is a lot of improvement Bitmain could make to the S9 on efficiency without moving to a new node.
 10%, likely.
 20%, iffy.
 30% - no bloody way at this point.

 And given the COST to design chips at 14/16nm, 10% isn't worth their time, 20% probably isn't (though I suspect they've tried some DESIGN work to see if they could get there), and most folks aren't going to consider 30% worth investment into at this late date even if they COULD manage it (or you wouldn't see folks buying Avalon 7xx series and EBang units that are ballpark 30% WORSE than the S9).

considering Whatsminer made some pretty significant improvements on the 28nm node process there's still more performance that can be milked out of 16/14nm. It's just a matter of when Bitmain releases a new chip and how efficient it will be. Bitmain's got very few competitors that can touch it in terms of performance in the SHA256 department right now.

 It is widely rumored that Bitmain will mine with a specific miner for a while THEN sell it as a "new unit".

 They HAVE sold units specific LABELED as "used" in the past, usually older units, at a fairly deep discount - but since the S7 is still profitable at their electric cost they've not done such a sale since just before the S7 was introduced, on the S5.

 They ARE widely known to have some serious quality control issues with the S9 model - if it wasn't significantly more efficient than any other model an "end user small miner" can easily get ahold of they probably would have nearly ZERO sales of the S9 by now.

can someone correct me,i heard that they sell refurbished miners
i really not sure a friend of mine said this to me he bought 8 miners and had to send back 6 and had to pay for shipping fee to resend them back

Up to the S9, they normally released a new generation about every 8-10 months - which they could do BECAUSE THEY WERE NOT MANUFACTURING THEM ON THE "STATE OF THE ART" MOST CURRENT SEMICONDUCTOR NODE for the older models.

 They can't do that any more, as the S9 IS on the current 14/16 node so they have to wait for the technology to advance before they can move to a new process node with much higher efficiency.

 I would NOT estimate they have 90% of the ASIC market - they might be close to that on SHA256 due to the long head start they had on the S9, but they definitely are not there on Scrypt or X11 where they had to play catch-up with a fairly large installed base.

Bitmain is a hardware manufacturer, their goal is to sell hardware. People on this site attack them for being successful and selling a lot of hardware. THATS THE FUCKING GOAL OF THEIR COMPANY.

The L3s were not brought over here because they did not get them certified in the US in time. Contrary to popular belief they now do make sure their miners comply with the US laws.

Or in answer to your actual question, its random. There is no set schedule for release of miners.

they have 90% of all asic machines made of any flavor or I say the capacity to make them ...compared to any competitor

sha-256 (like bitcoin) (Bitmain S9)

scrypt-pow altcoins (like LTC/DODGE/etc) (Bitmain L3+)

x11 coins (like DASH) (Bitmain D3)

They will pump them out like 'toasters', already the x11 miner D3 is never gonna make a profit

no reason to make a new miner, IMHO, no 'real' large-scale competition

it is bitmain..it is what they do

oh, and if they do..kick out a miner...it will be like the Original L3 which was ONLY offered in CHINA

and never on the USA site ...the L3+ pop'd on the USA site this last summer.....(L3 came out last December)

Thus, even if they do make equip, they may do it the same way again, and such equip will fill their data halls first for 2-3 months,

then released in China say in bulk for 2-3 months ..then with difficulty run up ..it will come to the USA

the only reason the L3+ bitmain miner works well this year yet..is that the LTC price went up from $4.15 USD April 1st, 2017 or thereabouts

to the $67 it is today...(so a fluke...I mean my Nov 2014 knc 300mh Titan Scrypt Pow miner and other Titans are still running full out, the 1st one is now 3 years old this month!)

so anyway, a new miner is fine I guess, we will not see it anytime soon for it to make a lot of difference (or not so much in my case at 12c kwh)

anyway, it is how bitmain rolls...kicks them out like toasters....and with no competition and economy of scale, the more chips/units you make etc the cheaper

the volume product..they have, IMHO, little need to make a new miner at this time....or hell for the next 6 months, again in my view,  especially if LTC price as an

As an example goes over $100 USD as a reflection of BTC price, say hanging over 8k or so...

so, if you are mining, at this time, my view is hoard and hold the hell out of LTC.....$10,000.00 BTC, say eventually, means (my bet) that LTC has to be $150 to $200 bucks or more...

or all pow-scrypt/sha-256/x11 hardware based POW coins (proof of work) are not 'poof' and forking BTC becomes the new way to make ALTS..thus they all fade from view....

anyway, how I see it (but what do I know in 2013 I drank the butterfly labs kool-aid....) take anything I say with a large/boulder-sized grain of salt....

(bitmain: we do evil well!) (tm: bitmain)

i want to know please at what rate of time bitmain release a new miner and where i can get to this informatio thx you very mach
