One still doesn't exist though
SIGH nevermind I don't get OP's hypocrisy. On one hand he says, on the first post, that he is sick of both camps and their non-existent logic. Then when legitimate arguments form he heavily sides against KNC, repeating the "Equally, each thread is filled with die hard supports who can't see the logic from the fud." that he himself is so apparently against. This is a problem because the premise of the title of this thread implies that OP is neutral, when as his replies show, he is not. Look for yourself, KNC supporters, bitfury's supporters, or anyone else.

I don't get it. Why you even discussing KNC?
Bitfury sells ASIC chips, KNC sells squat.
Compare them when they actually have a chip to compare.
As it stands now, it is like comparing Bitfury with Dragon ASIC (remember that one?).

thats a little unfair. bitfury took pre-orders just like knc did. bitfury has started shipping now. and knc is not yet late on its promised shipping dates of end of september so its a little unfair to claim theyre selling squat. theyre selling pre-orders just like every other asic company including bitfury. bitfury still has many pre-orders for its october batch, too. if we get to october and knc hasnt shipped any, then you can crow all you want

That's not quite comparable. Bitfury started taking preorders after showing a working chip, and then delivered working miners a few months later. KNC took preorders months before even having a chip, still doesn't have a chip, yet promises to deliver working miners in under 2 weeks. The odds of KNC delivering on time are rapidly dropping.

Punin from bitfurystrikesback.com (EU) and Dave from megabigpower.com (NA) took preorders, one week apart for cscape design hardware using Bitfury chips. They delivered the majority of the orders within 31 days despite having manufacturing mishaps.

Out of curiosity? It doesn't make sense that 55nm would TROUNCE something that should be 4x more power efficient. I said nevermind because his question is retarded, everyone is talking about KNC vs bitfury, look at the fucking 50000 page thread of KNC people talking about something that also doesn't exist. You can't have it both ways, either it exists and we're discussing it (hence nevermind), or it doesn't exist and its equally shit.
It makes perfect sense if you know anything about the different ways chips can be designed. If it didn't actually exist then you can't say if it's power figures are "bad" or "good", they are non-existent. If it does exist, and it's not as power efficient as bitfury, well, so what? It's also cheaper, for October delivery, which is all that actually matters as far as profitability is concerned at this point. The bitfury design is obviously really good - I don't think anyone is denying that. And KnC's chips aren't nearly as efficient as the HashFast/Cointerra chips. But timing matters far, far, more when it comes to mining profitability then the ultimate 'perfection' of the chip. And KnC has clearly beat those two in time to market.

What chips are you talking about? I far as I know they don't exist. I think you talk about specs posted on their sites. They have no chips.

Right is that not significantly better than their original claims of 250Gh/s and under 1000w? so what perspective do I need exactly? My point still stands they have been pessimistic so as to under promise and over deliver,
The perspective is you need to chill, seems like you're taking it personally that someone thinks bitfury's design is better, which is pretty much irrelevant. KnC's are cheaper, come with a case and are pre-configured and plug and play. Obviously a better deal. But they'll likely need to go for a full custom core to compete with other 28nm chips in the future. It is my thought, based on them saying they were working on a second gen design already, that they probably went standard cell on the first gen in order to get quickly to market with a viable product that they knew they could produce, while reserving the "work of art" for the next iteration. I don't know this, of course, it's just my speculation. But it's the way I would do it. Promise what you are sure you can achieve, and work to blow it out of the water in the meantime. So far, other than some marketing hiccups out of the gate, KNC has seemed the most professional of the lot, and I'm taking nothing from Bitfury on that. He and his collaborators did deliver the high grade goods ahead of everyone, almost when predicted in fact. That's outstanding. I think he and the KNC crew are worthy competitors in an arena where there are too many dodgy at best operators and a great many straight out scams. Had I been able to raise the funds for my own speculation, I would have bet on KNC to deliver first. Bitfury looked a little scammy to me. I would have bet wrong on delivery, but I still think in the long term KNC has the goods. I also think Bitfury does. This is an interesting game, is it not? Also, as Bitcoinorama pointed out, KNC have consistently had the mantra of "under promise and over deliver". We only know what they want us to see regarding their actual power consumption. They are playing a close hand, and it may actually be significantly better than we've been told. We will hopefully all know in a couple weeks. In the meantime, Congratulations to Bitfury. You did a bang up job from left field.

I also believe they had the chip hashing before they started taking pre-orders.

Oh look at this chip on my desk here [its actually a bottle of blue dragon sweet chilli sauce]. I'm not saying it won't hash, but I want to see it hashing before I consider it a hashing chip.

I think I know now why KnC cant compete with Bitfury on J/GH. And why they are moving so fast. And why they apparently dont feel a need for wafer or chip testing. They use Orsoc to make the chip. On Orsoc's site I see this: Retargeting of complex FPGA design from Xilinx Virtex5 into an Altera Hard Copy http://www.orsoc.se/?page_id=79KnC's chip is most likely not a custom cell based asic, but a hardcopy V implementation. Didnt KnC work on a FPGA earlier? They would just have used that design as starting point and things can go very fast then. Probably a good move too in this race, but not to win in power efficiency, nor die size efficiency nor cost per unit. But the surest way for time to market and probably more affordable NRE.

Where did they say that and what did they say exactly? You have to admit, the chip being nearly 4x the size of hashfast, worse power consumption, very fast tape out and promised post tape out implementations, apparently no interest in any tests and done by a company that promotes its hardcopy services. I dont know if they lied or what they said, but if it talks like a duck...

He wanted to spend more time on it.

If I had any doubts, this removes it: https://www.kncminer.com/userfiles/image/ASIC_PCB.jpgThats an altera cyclone FPGA on there. THats what you would use to prototype your design (and pcb). THe chance that a custom asic would fit, let alone work in the same board as an altera fpga is zero. Moreover they write underneath that picture: We will be using these boards to fully validate the entire setup. They will consume the same power, make the same noise level, produce the same heat and run the same RTL code. The only difference will be related to hashing.Definitely an altera hardcopy implementation.

It seems very unlikely any bitcoin asic provider is doing "full custom" in the sense that they design their own transistors instead of using standard cell libraries, provided either by the fab, or higher level libraries provided by the design house. That to me is the definition of full custom, any other definition is IMO bogus.
bitfury designed their own transistors. Just clarifying.
