EBang 14nm 6.3T (140W/T) BTC Miner for sale soon

[tbonetony]

Folks,

I came across this news today and would like to share it with you.

http://miner.ebang.com.cn/en/index.html

Currently they are a public company in China and recently launched their E9 miner product. Domestic sales started on December 4 and global sales starting on December 11.

Mining efficiency appears to come close to A7 but price wise seems to be around US$125/T.

I read their warranty (on domestic sales) has a coverage of 180 days. Looking forward to learning more about them.

If anyone has further information to share, please feel free to contribute too.

If this is a legit miner then it is a serious competitor for the A721 since it is close with the efficiency and little cheaper (no need to buy a Pi, apparently).

What I'm concerned about :

1. 1500w PSU looks really dense, 50% de size of normal server PSU or APW3 Bitmai, PSU
2. PSU has 4 PCIE plugs, seems a little light (KNC memories anyone ?)
3. Whare are they getting chips from ?

TBH, I haven't looked at all the website because it's slow as hell for me, has anyone tryed calling them on the number listed on the website ?

Plus I can't find info on whois request.

Keeping an eye on it hoping it's real

[Rabinovitch]

Nice toy, I would like to play with it using a screwdriver, a wattmeter and a noise meter.

The psu looks like a real issue

imgur is slow  but the 4 cables are 18ga

they are 12 inches long which means the psu is about 10 inches.

I do not want to do 6.3 x 140 = 882 watts on 4x 18 ga cables

so guys like j4bbrwock optimizer itop that sell 16 ga cables may be the better choice.

Plus also one must note that the PSU voltage output is rated @ 0 amps -- no load. Big whoop. Voltage under full load please?

As for where the chips are from, since they claim to be 14nm that means the Foundry is either Samsung or GloFo. Now what chips are used -- anybody's guess at this point.

[tbonetony]

Maybe I overlooked their PSU's. TBH I don't really care what crappy PSU they make since I have no intention using their PSU's any way. The only concern to me is the quality as you guys pointed out may render their miners in the same manner.

We have a lot more choices in PSU today but not so many in miners. I expect they realize they are a new player in this arena and they need to do more than a decent job to take shares from Bitmain and Avalon.

[NotFuzzyWarm]

Their site says that the chips are"DW1227, 96pcs (14nm LPP Process)"
Did a a search and nothing comes up for that chip# but the Process turned up GloFo as the Foundry that would making them. http://www.globalfoundries.com/technology-solutions/leading-edge-technology/14-lpe-lpp
If true, nice to have the chips made here in the USA (GloFo's 14nm foundry is in upstate NY)

agreed but from past experience  4 pcie jacks for 800-900 watts is very often bad.


I mean this from the miner end.

Their psu is a no go as running 800-900 watts on four 18 gauge cables is a no go.

Still one more thing it really looks like the avalon 721

[QuintLeo]

Looks a little more like that "hot water heater" company's prototype but a bit cleaner.


 PS output is rated for 120 amps - then you split that on 12 leads = 10 amps per lead = exceed the max rating of the CONNECTOR, much less the too-thin wires others have commented on already.

 I would avoid buying that PS.

Dosent seem that impressive for 14nm if the s9 is at 16nm and 0.098 J/GH :/

good to see competition tho, i wonder how DURABLE they are compared to the s9...

 14nm and 16nm are pretty much interchangeable for efficiency and speed.
 It's more of a "labeling" difference than any REAL difference.

 On the other hand, it's pretty sad that the newer entrants are settling for the 150w/TH ballpark.

I mean, we're lucky to be getting any competition at all. Always good to see this, but these guys have yet to prove themselves in this mining world. Perhaps they may be decent, nobody knows, but for now all we have is guessing and educated guesses. It's also safe to assume these guys don't have as much experience in the ASIC field. Give them some time and you'll get results.

Did an inquiry with Ebit about the 0.15 J/Gh on their ASIC.  Their reply to me was our machines do not use ASIC chips, kind of a scary reply.

What am I not understanding?  I thought you could only have a successful miner using ASIC, unless they are not mining Bitcoin.

Can someone help me out here?

rofl if that's what they truly intended to present. I found they have some English language barriers on their website.

I read an interview transcript with their CEO today. When asked how they see themselves in the market while stronger competitors like Bitmain, Avalon, and Bitfury are already in 14nm with similar or even better efficiencies, the CEO responded "The quick money age of mining has long gone. From now on and forward, mining is going to be a long game so one critical factor that matters to all miners is an adequate warranty system that can back them up." I like this statement a lot and want to see they actually put it into actions.
According to the interview, they currently have 13 service locations and more to come in China. They offer 6 month warranty on the miner in compliance with China's national consumer policy standards.

Anyway, they will have a presentation on December 11 and open global sales that date. I am looking forward to its outcome.

i fully agree, mining IS a long game now.
well now, THIS might make things interesting...
how often do we say we would even pay MORE if we had some ACTUAL warranty/we knew the machines would last even a damn YEAR :/
6 MONTH warranty, thats pretty sweet for a miner (from what i have seen)

First Chinese review is out:
http://www.cybtc.com/thread-16686-1-1.html

Power consumption is disappointing, 1018W using their PSU @ 93% efficiency.
Actual hash rate is somewhat *higher* (6.4~6.5 vs 6.3) than advertised.
Noise is comparable to S9 full throttle.

If you can't read Chinese, use google translate.

[BigBoom3599]

Wow, if this is real it might cause some competition again in the ASIC industry would be exciting to see them compete against Bitmain.
We may even get some price drops out of it

0.16W/Gh makes it no chances bitmain will drop prices

[QuintLeo]

Avalon 721 ballpark efficiency.

 They would have to price this miner 20-30% less per TH than the S9 before Bitmain felt significant price pressure.


 Do note that Bitmain DID drop the price on the R4 recently - apparently the Avalon is quiet ENOUGH that Bitmain felt it represented real competition for the R4, so they dropped the R4 price down ALMOST in line on a $/TH basis to the S9.

 It's also interesting to note that the S9 price DROP got partly rolled back about the same timeframe.
