Except for KNC, it seems like all of the other ASIC vendors are having difficulty bringing their 28nm designs to market.  I'm starting to think some of the millions of preorder dollars and bitcoins are in possible danger of never being returned if the designs ultimately fail.

And it doesn't help confidence levels when the ASIC vendors stop communicating their progress and future plans!  

So what's your guess on who will be the next bASIC?  Or do you think everyone will at least deliver some kind of working miner to investors whether it meets planned specs or not?

cointerra has been quiet lately it seems (but i dont actively follow them) but they were not planned to launch until 2014

KNC gen 2 in March 2014  :D





(half trolling, would not be that surprised though... and yes, gen 2 will likely be 28 nm as well and no, I don't want to defend that statement)

Too soon for 14nm then.  22nm?   ;D

28 nm as well

Well, I hope that KNC has room for improvement on their first pass at 28nm.

I'd really be interested to see what Bitfury can do at 28nm since they are already more efficient at 55nm than KNC is at 28nm.  And I think that Bitfury still has some improvements they can make to get the specs of their 55nm die closer to the projected 5GH/s per chip that they were aiming for.  They may even be able to go to a less costly die process like 32nm and still kick everyone's ass.

I love that guy.

I used to love him too, but not anymore because of his high prices.

Are we referring to "Tytus" when we say "Bitfury"?  He is kind of an enigma... unless you can speak Russian, I guess.  He never posts in the English language forums.  It would be nice to know what he was up to.

Not BFL, since they just announced that the first Monarchs should be shipped by the end of December, with HashTrade, founded by the Jacobson Brothers, receiving their units in about March/April.

BTW, has anybody been able to hunt down the tx for that $1M down payment transaction?

We are talking about Bitcoin miners here, not tea cup warmers :P (even if it's a million USD worth of them)  ;)

in a few days all the october pre-orders will be fulfiled, and i expect a drop to reasonable prices ($12 per chip and $300-350 per h-card)

Concur.  I see them as being the most likely, followed by HashFast.

The idea of 250W TDP in a single die just seems like the wrong approach to me.

Esp when that's the theoretical power consumption - which no one apart from Avalon even got close to. Estimate 250 = spec for 450, which isn't going to happen.

About 2-3 years too son for economical 20/22nm.

Well KNC got it right (came in significantly under simulation) so it is more than just Avalon.

Hyptohetically there is a miss and it does use 450W vs 250W at nominal voltage and clock.  Power is all relative.  It would be 450W at a given clockrate and voltage not at all voltage and clock speeds.  Lower the voltage and power drops by the square.  Lower the clock and power drops linearly.  If the system absolutely can't use more than 250W there is some combination of clockrate and voltage that gets you there.

This is exactly what Bitfury did. 

Of course this is true, but only if we don't care about hash rate promises. Which we do.

Well once again it is no different than if a small chip misses.  Bitfury did and used more chips to deliver the same hashpower.  Obviously they would have rather not missed and made an even larger profit but they adapted and met their promises.

If you miss you need to clock/volt down the chip and use more chips. 500 GH/s chip or 5 GH/s chip you still need to adjust.

... or they could waste precious time and do a respin.
