how are BitFury's more efficient?

400 watts vs. 1000 watts.

It's not 1,000 watts though. That's a worse case scenario...

It's not about rising difficulty, it's the question of, if the difficulty were 1 billion today, would the device earn money above its electricity costs. The answer is yes, about $17.50 a day:

Even that depends drastically on your electricity costs which vary from < $.08/kw to $.22/kw. In Europe, power is even more expensive. Obviously if you have free power, then that's a different story - once the purchase costs are paid for, then you never shut it off.

It also depends drastically on the price of bitcoin

Long story short, a KNC miner has the best prospect of long-term mining profitability around, except for perhaps Bitfury whose chips are more efficient. (But for how long? Gen-2 KNC device will probably beat them on that metric).

how are BitFury's more efficient?

Bitfury's chip is more efficient in terms of gigahash per joule of energy. This is likely because they did a full custom ASIC. Maybe the actual device will be a bit closer together on efficiency due to one being solo chips and the other being VLSI, but Bitfury's chips is significantly more efficeint.

It's not 1,000 watts though. That's a worse case scenario...

It's probably gonna be like 750 watts. Bitfury is still winning that battle.

1,000 watts is a best-case senario, because KnC does not have actual chips to test.

lol 4 chips vs 270 chips.

GG

and who actually has a DIY miner of any kind hasing right now?   anyone? not a dev board...  one that went through all the hands and mass produced and shipped off to customers?   Who the hell knows how great the turnout ratio will be with those

Bitfury doesn't win the battle at all, it's about ROI of which  power consumption is just one part.  1,000watts costs most people only a few dollars a day, trivial when you compare how much BTC  the things produce.

No one won any battle until units are hashing in customers hands.

Only winner so far has been avalon batch #1, the rest (including avalon batches 2 and 3) are loosers or just promises.

I wish i was a looser with an avalon batch 2 or 3...

True, tho we were discussing longevity, and when it comes to that the game is gh/joule. The other major factor in mining longevity is the price of bitcoin. If it doubles before your miner is unprofitable on electricity costs, then that increases the amount of time you can profitably mine as X efficiency.

So, has anyone noticed the dimensions? Looks like 20in x 16in x 8in is now stated on the Jupiter product page - that is a pretty drastic change from the originally stated 6in x 6in x 8in..

[erschiessen]

Lots bigger than I expected.

[Anenome5]

So can anyone tell us what the heck this is and means?

That's what she said.

Sorry, I just couldn't let that one go

There is no way a 1000watt devices would have been 6in x 6in x 8in unless it was a fan heater, even then it's a bit small.

Agreed. That said, it's still a _big_ bump in size, and I'm glad I noticed it as I'll need to reevaluate where I'm going to have room to put it.

*note disclaimer, I own no hardware (other than temporary stock), have no preorders and no affiliation*

Something is wrong here with this simulation. Its a side view of the board at the bottom, with package and chip slightly above, with a 4 heatpipe heatsink. The left, blue side is showing an ambient intake of 25C, exhausting at ~50C.

Now, look at the chip area; its deep oranges at best. Their own simulation is telling us the chip's heatspreader [not even the chip itself] is somewhere between 125-150C. I don't know a consumer grade chip that gets even close to these temps, nor materials creating using conventional techniques that would withstand 24/7 at these temperates.

Its hard to tell without a larger image but it looks like an auto scaled legend, so its reporting a spot temperature somewhere on the chip of 223C. I am not aware of the limitations of the exact simulations they ran, but if mine came back and showed that I would be weeing myself.

tldr: Either that simulation is made up, fake, wrong, set up horrifically - or the chips are running @150C+.

Aaaaaaand that's what she said after

Just received this update? Talking about March 2014? HUH? I thought these were to ship this year October? What's going on? So there will be three entire months other companies will be shipping miners and KNC will not be? That doesn't make sense. They need to understand they are also in competition with other mining companies. Not just themselves, right? I don't get it. You mean I could be waiting the entire winter months after paying months ago??? Damn, sounds like BFL all over again, no?

You're misreading it. Stop pannicking lol

They will stop shipping December-February. Which means that they will be shipping in September (or October).

"Meaning that once we have taken the difficulty up at the end of November we will not release any more hashing power for 3 months. "

Why would they release new products in March if they haven't shipping the original products?

Its quite the opposite of BFL. They actually have a roadmap laid out and plan on sticking to it as close as possible. They're not only predicting when they will ship, but when they plan on finishing their shipments and their future offerings. Its pretty reassuring. I'm glad my payment cleared.

Oh, ok. I'm sorry for not reading into correctly. I was thinking I would be sitting here all winter, having paid for my KNC miners a month ago or more and then not get anything until 2014. I guess I'm just being a little "glass is half full" on this because that's pretty much what happens around here with mining companies and how they operate. At least with the dealings I had.

Sorry for jumping the gun.

No, it means they have a shit load of integrity and give a damn about their customers achieving ROI.

Re-read, and don't panic!

Yes but OTHER miner companies will still be selling and possibly SHIPPING out devices to customers while KNC sits out for a few months. I can see this being good if no one else was ever going to ship anything, but I'm pretty sure other companies will be shipping products out, no?
