It's not just the actual manufacture time.

 You have to order the chips, get the order confirmed, get the order SCHEDUALED for when the line has capacity available (this is the PRIMARY issue right now for most ASIC chip makers), get the line set up, make the wafers, cut the chips, test the chips for defects, package them, ship them....

 The non-manufacturing time is the majority of the delay between when someone orders chips and when they have usable packaged chips - and it's a HUGE majority of the time for folks working on recent process nodes as the lines tend to be "booked out" for quite a while at a time. 14/16nm is really bad there, you're looking at MONTHS of lead time because the lines are running at capacity and there's so much of that capacity booked out or "contract locked" to specific manufacturers.


 Why would Baikal "suddenly have 500 in stock"?
Gee, perhaps they got a shipment of chips in over the last week and just got them built?
After all, making miners is what they DO....

 I've never had a card last that short of a time on mining - 3 YEARS is a lot closer to the norm, and on the low side for the cards I've HAD that long to date.

 No, they've been very closed about that - but so have ALL of the other miner manufacturers for ANY ASIC-based mining machines.



 The iBeLinks aren't going to achieve ROI in 2 months - it's already been almost that long since they were sold out and they don't appear to have shipped a significant number of them yet (and if they have shipped any it was to the folks that ordered back in May or so when they first went on pre-order).

 They *might* achieve ROI in 2 months of OPERATION if they start arriving before the end of the July, but when it takes someone 2-3 months to even GET the miner that's NOT a "2 month ROI".

 They're also going to bump the total network hashrate up a LOT before Bitmain or Innosilicon even START shipping the D3 / A5 at all, which will make it take longer for THOSE miners to achieve ROI - and THOSE miners are looking at 2 months or more of "pre-order delay" before THEY start shipping, presuming Bitmain and Innosilicon meet their announced shipping dates (Bitmain has a pretty good record there, Innosilicon is mixed).

 Innosilicon is generally considered to have SUPERIOR customer service to Bitmain - which isn't saying much, though Bitmain is considered to be a lot better than Baikal at dealing with customers.
 Bitmain also has a POOR record for reliability on their recent-gen miners - the S9 is NOTORIOUS for losing hashboards, the R4 doesn't appear to be any better, and it seems to be a significant problem with the L3+ as well.
 The T9 seems to be the ONLY recent Bitmain model that doesn't have this issue to a major degree.
 
 Innosilicon, on the other hand, had some issues with the first 2 batches of A4 miners, FIXED the issue in the third batch, and worked WITH owners of the first 2 batches to fix THOSE miners as well.


 I did not say NOR IMPLY that Nvida, Samsung, or AMD are ASIC chip makers.
 Current generation ASIC mining chips are made on the SAME foundry production lines as current Apple, Samsung, Nvidia and AMD (among others) GPU CPU and Smartphone chips - which is why the ASIC mining chip makers have to compete with foundry space vs the "big boys" - and those foundries have been widely reported to be running at full capacity on their 14/16nm node lines for as long as those lines have been running at all.

 Good luck finding such a unicorn.

Not sure why we're seeing the current increase, the Bitmain "July" batch looked like it was all shipped out the first 2 weeks or so of the month.
Perhaps Bitfury finally got some chips shipped to a large farm?

 Still not seeing any reference to a G2 at the 1200 watt level, though they did make a P2 PLATINUM rated 1200 watt.

 8 + 6 shouldn't be an issue, the cables on those supplies for PCI-E power are heavy-duty enough to handle 225 watts on one of their "dual" connector cables without issue.

 Fine for 220 usage, but EVGA ships the G2 1300 with a 15-amp rated 14 AWG power cable in the US for 110 usage for a reason (as does Seasonic on the X-1250 and I THINK on the X-1000).

 That is assuming 120 volts, which is normally NOT the case.
 That is also an INTERMITTANT rating, for 24/7 usage you are required to derate the amperage by 20%.

 It's better to figure at 110 volts as a general rule vs. 120 as most places do NOT see 120 volts on a consistant basis (for reference, I've NEVER seen 120 volts out of an outlet that was wired properly, though I've seen as high as 119 ONCE - 115-117 is a lot more common and 112 I've seen a few places).

This is all assuming you have a mining area that is COOL - once temps start heating up you also have to start derating for temperature.
Breakers in specific are generally rated at 40 degrees C, which is only 104 F.
Keep in mind that the breaker box retains some heat, breakers next to each other will retain some heat, it's not uncommon for a 100 degree F ambient temperature to have a 15 amp breaker TRIP at 10-12 amps of load on it.
Breaker boxes are RARELY positioned to have any airflow over them, and VERY rarely set up to have any airflow THROUGH them.

 Wiring can also be an issue, since it's usually run through the INSULATION in a wall or ceiling, which will also retain heat.

 Outlets ALSO have heat retention issues, since they are normally installed in boxes in the wall surrounded by insulation and the CONTACT resistance tends to heat them up noticeably.
 Ever notice how the plugs on molded power cables are usually the hottest part of the cable? Contact resistance is WHY.

 ASIC payback vs GPU payback has varied a LOT even in the last 4 months alone.

 Bitmain is *primarily* in the "sell miners" business, I suspect most of their in-house mining is done via their HASHNEST operation or as "unit testing" for 1-3 days when they finish building each miner.
 They probably like the "certainty" of having their money RIGHT NOW when they sell a miner vs. the risk of mining and possibly NOT making as much, plus they need to pay for the "next batch of chips" somehow.
 I SERIOUSLY DOUBT it is about "help benefit the network".

 The A4 will earn a bit less than 60% of the LTC income of the L3+ = assuming both have equal reliability - current specified hashrates on both appear to be reasonably accurate.
 From many reports though, other than the first 2 A4 batches the A4 has superior reliability to the L3+ (and Innosilicon worked with folks to FIX those first 2 batches that had firmware issues to the point they are supposed to be rock-solid like the later A4 batches now).

 Do you mean the EVGA G2 1300? I'm not aware of an EVGA gold-rated model at the 1200 watt level.

 If so, 3 1080 ti will work VERY comfortably and 4 should be viable if you keep the TDP down some on all 4 cards.

 3 x 1080 ti and a 1070 should work fine if it's not a high-TDP 1070 model like that monster MSI with 2 power connectors.


 I've noted that a lot of mining will "spike" the TDP occasionally no matter WHAT you set it at, though.

 How so?

 Innosilicon has been quite consistent in their naming scheme - except they never got around to actually releasing the A3 at all (I've seen commentary that the A3 wasn't going to be efficient enough to compete by the time it would have been released as WHY Innosilicon never pushed it into production).


 They seem to be pointing at the "turbo mode" 38 GH/S as justification for the $10k pricing - though their specs make the A5 very little more efficient than the D3 at that point.
 This is similar to how they positioned the A2, and not entirely unreasonable as I suspect most A2 units have spent most or all of their time in "turbo mode" (though the ORIGINAL PS in the A2 did NOT support full turbo on the "110 Mh/s" units, some later units seems to have upgraded the PS to one that could do so).


 If I remember the timing right, the original model IBelink showed up around Febuary 2016, the Pinidea models in March 2016, and the original Baikal in May 2016.
 I could easily be a month off on those dates though, but all 3 were DEFINITELY available by June 2016 (or had already sold out).


 I don't think Innosilicon is including free delivery, but they are including a free power supply for early orders (probably left over stock of the SAME power supply they put in late A2 110Mh/s units, which have proven to be fair reliability).
 I doubt the shipping cost is going to be significant to folks buying these though.

 Their fees are insanely high to do ANYTHING, therefore they rip you off to use their garbage wallet.

 Thank goodness Counterparty is NOT needed to participate in FLDC.

 They fixed that - somewhat - but as of a minute ago they are STILL only quoting Bitcoin at $2370.

 $4-$5k would be TOO low compared to the D3 if both units hit their stated specs.

 Innosilicon dropped their MOQ to 1 on the A5.

 Also, they didn't announce it 'till much later in the product cycle than they did the A4, which means they SHOULD hit their stated specs quite a bit closer than the 3 "tiers" of "announced" A4 specs.

 The A4 was also the first time they announced specs on a unit before they had production chips on hand - they didn't pre-announce the A1 or A2 AT ALL, and the A3 never had specs announced NOR ever got released.


 With that said, Innosilicon DOES need to drop the A5 pricing to more like $6-$7k range to be competitive, even if they DO meet their specs.


 Also keep in mind that Bitmain has had issues in recent times meeting announced specs (how many "14+GH/s" S9 batches do you see any more, and how many of those early batches had MAJOR issues before Bitmain retuned later batches for lower hashrate?) AND Bitmain has a far worse record on reliability since the S5.

 Given the stated power draw on the D3, I don't see ANY chance of them doing a "D3+" in the same form factor.


 Traditionally, Bitmain aimed at "6 month ROI" back in the day when pricing their miners, but competition sometimes modified that (ref the S5 / SP20 wars), and they seem to have shifted the aim point to somewhat longer starting with the S9.

 Pinidea has been "sold out" for well over a YEAR now, with no sign they will ever have anything for sale again to date.

 Why do you keep ASSUMING they are "restricting the supply of miners"?
 Why do you ASSUME (falsely given more than a few comments about much more RECENT Baikals aquired by quite a few folks) they haven't sold "outside of China since Dash spiked in March"?
 Just because I have a REALISTIC knowlage of how getting chips works AND HOW LONG IT TAKES TO DO SO does not make me a "fanboy".

 You on the other hand seem to need a tinfoil hat to go with your ridiculous conspiracy theory.



 I suspect the Baikal cubes will remain profitable on X11 for quite a while, though it might drop for them compared to the alternatives they can ALSO mine.


 It takes a LOT more than a "change of software" to add X13 and X15 to an X11 ASIC miner, you have to design the ASIC *ITSELF* to support the additional steps those other algos add to the X11 algo.

 I doubt it, as the limiting factor for Bitmain on miner manufacture is almost certainly the ASIC mining chips - where they are fighting for LIMITED foundry space against the "big boys" like Nvidia, AMD, Apple, Samsung, and such (Intel probably isn't a factor in this since they still have their own foundries).

 Bitmain wasn't  the first to market even in this SECOND wave of X11 ASIC miners - iBelink had their SECOND gen miner out a couple months back, and seems to have sold out their entire first batch and probably started shipping it.

 a) Never, the L3 was replaced months back by the L3+ in the Bitmain lineup.
     No clue when they will make preorders for the next L3+ batch available, you'd have to ask THEM and I doubt they are saying.

 b) Innosilicon A4 - which is also "out of stock" right now but they ARE accepting preorders for their next batch - MOQ of 5 though.
     older used less-efficient miners like the Innosilicon A2, the KNC Titan (those that haven't died so far), the Alcheminer, and the even lower efficiency stuff from Zeus and the Silverfish and the Gridseed GC3355 based stuff etc.

 It seems to be a tradeoff on which is "best" - after Innosilicon got the issues with the first 2 batches of the A4 fixed, they seem to have turned into very solid A2-level miners, but the L3+ is lower cost per hash AND more efficient when you can get them but seem to have the issue Bitmain has been having with ALL of their 14/16nm miners of hash boards dropping out or dying quite a bit.

 Odd, I've not seen a significant count of hardware errors on my A2 units, but I do remember seeing a similar count on my S5 units.

 Perhaps you're pushing your units too hard, or not keeping them cool enough?



 I suspect Innosilicon is going to HAVE to drop the price on the A5 down to more like $6-$7k range pretty quickly if they expect to sell a significant number of them - even if they DO hit their stated specifications closely.
