BITMAIN launches 4th generation Bitcoin mining ASIC: BM1385

[aarons6]

i wont buy anything over 1.5 btc..

with return being tight as it is. plus the block half so you will make very little roi before these are useless, and the fact that difficulty will most shoot up as soon as these are released due to everyone with s2 and s3 changing them out its not a good investment.

Do they ever mention what the hashrate will be? Or, just the power consumption per Th/s as 230 watts?  

I may be stretching, but a 2.4+ Th/s machine for <$700 SHIPPED would be amazing.

 The 230watt / th is THE hard figure they've mentioned, though the fine print on that specified chips running at .66 volts.
 Presuming they stick with string design, that DOES specify 18 chips per string.
 It would be VERY VERY iffy for them to try to cram 54 hash chips on one hash board.
 Therefore, the general consensus has been 2 hash boards, 2 strings per chip, appx. 2.3 TH at appx 550 watts ballpark for an S7, at around 4 BTC PLUS shipping (or around $930ish at current BTC pricing). Call it $1000 or so shipped.

That appears to be a fair assessment.  With those number, with no difficulty increase, ROI is ~300 days.  That is going to be tight with the halving in less than a year and possible difficulty increases.  Bitcoin price again is a huge unknown.

Doing the math, what was your energy cost? Considering the halving and diffuculty increase 300 days are too much.

 I think I was figuring 10 cents / watt, but I don't think I factored in diff increases. Someone mentioned somewhere that Bitmain prices their miners to ROI in 250 days without diff increases, so I plugged the numbers I had estimated for TH and watts into that.




 

 There is absolutely no consensus that it will cost $930, none at all.

 

 https://bitcointalk.org/index.php?topic=1159185.0

 Most of the entries seem to be clustering pretty close to 4 Bitcoin - which was worth about $930ish when I posted that price estimate.
 (Edit) Just went back and counted, an outright majority of entries are guessing prices between 3 and 5 BTC, the rest are all over the map and some of the rest are insane (like the ones at 1.something or 11+).

 I'd be HAPPY to see it at 3ish Bitcoin or less, but I don't believe that is even CLOSE to a reasonable expectation after factoring in the additional efficiency vs. the S5 - do note that the last S5 price was right about half of that estimate, do you REALLY think Bitmain isn't going to charge a premium for the DOUBLED efficiency vs. 2 S5s that hash at pretty much the same rate combined?


 

 But it is hard to tell if they come out and no one else has something to compete.

 The only current competition for us non-HUGE mining corps is that Sfards SF100 massively overpriced joke, for now. That will change, but looks like won't be 'till December or whenever Innosilicon released the A3 and miners using it start hitting sales (Lktec has already announced. Innosilicon themselves I'm rather certain will do an update on their Terminator as well, in both SHA256 (A3) and Scrypt (A4) versions.).


 Even at 2% diff increase for the forseeable future (which seems to be about what's happening the last few weeks, about when Bitmain started selling "used" S5 units presumably due to internal production allowing them to replace them with S7s) the S7 should be solidly profitable after the halfing and for quite a while after that. The *S5* will get very very marginal as of the halfing, depending on your electric price.

I will probably not buy anything above ~3 BTC for ~2.4Th/550-600W.

Depending on electrical costs and the avg price of BTC over the next year, 3 BTC (S&H included) is the max for that size of rig when you include the halving. A safer bet is 2 - 2.5 BTC.

1.5 BTC is more comfortable given the deluge of power that will hit the global hashing network when all these efficient devices hit the market.

Well its over 7 BTC.  Twice the size we were anticipating.

just as i said: they gave up on miners with psu in case(i might be still wrong about this one)
                      they will sell the middle units like those on s5+ but with the new chip and call it s7(s7+ might be also available very soon)

Do you know if it went on sale already and sold out?  if not do you have any idea when the sale date is set..  Thanks

In their S7 thread they said it will be available "soon". It hasn't sold out.

It'll be ready soon

"Batch one scheduled shipping date is in late September of 21~30. If shipping out 10 days later than the scheduled one, it won't be considered as delay."

Thanks for the info.. ill keep an eye on it..

0,216*1.0638 (ideal string design + platinum PSU at peak 94% efficiency) = 0.23
This 230W at wall is to idealistic. Real world numbers will be 250-260W/TH.

230W is at the wall, it includes PSU and any other inefficiencies. They've not been wrong on the previous 3 generations so I'm not sure why they'd get it wrong now.

Looks like they did get it wrong.

3. Power Efficiency: 0.25 J/GH (at the wall, with AC/DC 93% efficiency, 25°C ambient temp)

It would take me 6 months to ROI with an S7 here if diff and BTC stayed at current
Power is 22.3 cents per KWh in NZ...

Hosted @ 10 cents per kwh or cheaper it would be viable though.. hmm

Worse than that (same electric rate as here in the UK it sucks !!!)

Cost: 8 (not including shipping)
Income: 0.04504819
Power: 0.02840316
Net: 0.01664503

8 / 0.01664503 = 480 days

Sorry

hi,
has any one still have S7 batch2 coupon ?  
if you have these, i want to buy 3 S7. so i need 3 coupon  
my id : Turgan

also i will publish S4 efficiency & chain problem solution pdf soon.
thanks...

Well there's no "Batch 2" coupon, the coupon all expire on 12th of October. If batch 2 hit by then, then i have one to sell to you at market price, 0.1BTC, feel free to take it to my thread or in PM;

That's a big jump in efficiency 

[Abiky]

I'm saving most of my earnings to get my hands on the new Antminer S7. The best thing about this miner is energy efficiency so I would save money and reach ROI in no time. This has been added to my wishlist. I think I'll be selling my good old Gridseed GC3355 to earn some extra cash

What is your electricity price?   I don't think of reaching ROI in "no time" happens much anymore.

It's kinda a long game that takes a while.  I miss the 90 day ROI time, now it's in hundreds of days.
