Doesn't seem like it's helping the time to market if they're not gonna be shipping units for three months anyway. Making a case is a heck of a lot faster than making enough 7nm ASICs to put in it, and getting them installed on the boards.

Canaan's machines are better thought out in pretty much every way. If I'm remembering right, Canaan was started by the engineers left in the rubble of Avalon ripping off most of its customers and skedaddling with all the money. Putting more engineers in charge of a product instead of bean-counters is probably a good way to go if you want something to actually work well.

I appreciate the insight but the argument isn't they can't, but why they don't. Ease, profits, turn to market. Or is there more I'm missing?


Yeah at least how I look at this gear.

Anyone with an understanding of mining won’t want this gear.

Two fans pull 62 watts.

Must force feed it cold air.

So if margins stay tight I am going to lose quite a bit of money feeding cool air to it.

If a fan has an issue gear may over heat.

So basically this miner is for an ac hosting place with crazy cheap power. And is short on space.

I simple don’t see why you buy this using 82 watts per th and needing ac

Over the Avalon the s9 or the t1/t2. All of which can survive a 90f room with fan cooling.

Well this should make the GMO Investomers feel a little more comfortable, from the July issue of Photonics Spectra: Extreme UV Keeps Pace with Moore’s Law. Good article describing it even if it is written with more of a simplified-for-marketing vs whitepaper style.

EUV power is getting higher and more stable & mirrors are lasting longer so come Q4 7nm is finally looking to become economical for commercial production of chips vs the current Engineering samples/pre-production status.

24 TH for 2 KW?

Not very impressive if they're actually using 7nm parts.

Innosilicon has done better than THAT on new nodes....

I'm no longer legendary just in my own mind!

right now  gmo claims 82 watts per th

innosilicon claims  72 watts per th on a down clocked t2 turbo

and pangolin claims 65 watts per th on its new m10

so

24th doing 2000 watts  for gmo ships in OCT

33th doing 2145 watts for pangolin  ships in Sept

no real verification in field tests by real miners as of today.

but GMO is in trouble if  both innosilicon and pangolin deliver on their claims.

And Bitmain's pending announcement will most likely fall into competing for market on newest specs/efficiencies.

I would think it would , but I never saw them  trail in every single  type of miner they  were selling.

Already back to this gear it now looks like a terrible investment.

As both innosilcion and pangolin claim to work better.

and both innosilicon t2 turbo  releases sooner then OCT1

as does pangolin M10.

Yea, GMO is doing it wrong. Their pretty much selling asics that plan to will host them selves. No developed for most mining facilities and date is way to far to even call them a market competitor. Then they will probably keep changing their design every few months as efficiencies or hash rates increase. Hopefully the prior.
