Wu Announces BM 7NM pending Miner release. 42 J/TH

[Guinsanity]

Well something is definitely going on since Bitmain is now out of 16nm chips (from my sources). From what I hear they are full-steaming for production of this new 7nm wafer. Bad news for anyone with an S9 since there will be no support in 3 months (but it'll be trash by then anyways so...)

Better late than never.

it won't be trash in 3 months more like 9 months.

most of the network is s9 it will take more the 3 months for buyers to replace them.

Unless the s11 does 45 watts  and 30th with a built in psu and costs under 1000 usd.

That would sell well even in the frozen usa market it will sell.

Or bitmain prices high like the m10 at 1600 which won't sell to usa miners quickly.

[Guinsanity]

I think bitmain gonna do better efficiency with same price as M10, including PSU.
They not gonna sell so cheap s11 gears

I dont see any reason why people would want to pay extra for a built in PSU. Anyone doing mass upgrades from the S9 already has power supplies, most likely of a higher quality than the ones that come built onto miners. I know the last thing I want is another proprietary part in my datacenter that I cant just switch out on the fly.

if it is all they sell you will have no choice.

the more i think about it they will do a 40th unit using an attached psu

getting 48 to 52 watts a th.

sold at 950 to 1050  it kills everyone price and efficiency wise.

and forces you to buy it with the psu attached, since the psu needs to handle about 2100 watts.

One thing I've wondered about these attached PSU machines (never owned one). Do the manufacturers make them in a way that you can't use an external one in any way? I've run most of my equipment on 2400W PSU's so in theory if their PSU fails I would have spares.

That is assuming of course that they want to sell it with an integrated PSU. I'm not going to lie I don't see the appeal in it myself. It's just another piece to wear out; so unless they have an abundance of them laying around or on order for pennies on the dollar I wouldn't waste my time. From a consumer standpoint I would probably pay a little extra total cost getting setup, for the convenience of choosing my own PSU.

[philipma1957]

well  we are in tight margin times.

bitmain sold a lot of s9i and s9j cheap  at least ⅔ of mining gear is some kind of an

 s9
 s9i
 s9j

they mostly have disposable psus.

if bitmain can put out a 45-50 watt per th  unit we will need to buy it or not mine

a 10 cent per kwatt s9  is in the red

and if bitmain pushes this with that big psu

 a 6 cent a kwatt s9 will soon be dead

but that s11 will be a money maker.

bitmain is exposing what unchecked selling of low priced miners does to the industry.

thats the frustrating thing. I have THOUSANDS of 2450w PSUs that would go to waste in this scenario. Hopefully they do like in the past and make a version with and without. Previously all of their built in PSU systems were for the chinese market only.

Yeah it would hurt a guy like you.

But boost their psu sales a lot.

[ccgllc]

I have PSU issues much more frequently than I have miner issues.  If the PSU was built-in my farm reliability would really go down.

Hopefully the (potential) built-in PSU will be modular and simple to change/replace. Looking at my T2T, I can imagine tinkering and replacing the built-in PSU with a APW5 by removing the PCI cabling and using the bolts. I can also imagine killing my T2T this way haha. Has anyone ever replaced a built-in ASIC psu with an APWx?

this is funny as my t2turbo has crapped out at the solar array..  I may be doing this I am not looking forward to it.

I will be driving over to the array today to figure out what it did.

Hey Phil, I wouldn't get my hopes up on the efficiency. There are alot of problems it seems with the 7nm chips and it is very hard to get good efficiency on them. It may get something around 60-70watt/th but I seriously doubt anyone will get anything below 50watt/th in the next few years. I'm not a chip engineer so I don't know the whole detail so perhaps others that are more knowledgable would chime in as to why. But yea, so far the big brands are struggling to get the performance to where they want it to be. I expect Bitcoin mining to shrink if anything (in terms of miners) in the coming years. Anyone above 0.05kw/hr will be hard pressed to stay in the game.

yeah we are hitting the wall as diff is going sideways and we are creeping down to where only 2-4 cent power works.

42J/TH ... didn't happen yet. Hope Halloween will bring some candies.

rumor has it they had another fail on wafer burn of 7nm chips.

  some say the third fail.
 some say the second fail.
