That said we only KnC's package size, not die size. Large package size, does not necessarily correlate to a large die size.

Ill grant you that, but I havent heard anyone refute hashfast's argument that the minimum estimate of KnC's die size based on the package/underfull dimensions would be on the order of 900mm³. Thats not just a little bit bigger, thats an epic size.

Although you wouldn't conversely be able to house a large dies in a small package, but there could be many reasons behind the choice. I could try and press them on this in a few days, but if they haven't mentioned it now, I presume they will likely be more cagey this time round when they have nothing more to prove than performance figures.

Please do also ask about the PCB testing with the cyclone fpga (see my last post edit at the end).  How come their "full custom" asic happens to be electrically and pin compatible with an altera cyclone IV (and therefore, hardcopy IV) if its not a hardcopy?

https://www.kncminer.com/userfiles/image/ASIC_PCB.jpg

It just doesnt seem very likely or credible to me.


edit: should have read the text better.

Puppet, mate, on your link that board with the FPGA and the pen, could that have been a dev board for testing?

In the video they released the other day those quadrants no longer appear to be present?

Take a look apprx ~10 seconds in;

http://www.youtube.com/watch?v=4IdiBynh8Wo

I'll ask, but it makes sense, i think. I mean the board being manufactured is different.

Yeah there is a reason I edited the post Smiley That does make sense. I didnt realize those boards only held a single large asic.
Did I say large? I meant frigging unbelievably gigantic.

I'm sure most here don't care if KNC chips are, indeed, full-custom or standard cell -- as long as the performance is within spec.  I know there are some 28nm fetishists around, who think 28nm node = god, but hopefully Bitfury 55nm chips castrated their nanolust.

I was just taking a look to this prediction for a Jupiter:

http://btcinvest.net/en/bitcoin-mining-profit-calculator.php?diff=148623691.94537259&dcosts=7500&diff_mincrease=35&blpbtc=25&dhsmhs=500000&diff_mincreasedecrease=3&btcusd=128.53&dpowcon=650&btcusd_mincrease=0&pcost=0.25&calcweeks=20&dleadtime=1&action=calc#

Some notes:
- Optimistic hashrate of 500GH/s
- The cost of 7500 is including upgrade from Saturn to Jupiter, sending costs, power supply, etc.
- The difficulty setting I think that is conservative as it decreases too fast when we know that many asics are coming and it will contain higher jumps.
- If they deliver one week later is even worst.

Even registered as a company with electricity expenses covered and mining device as company expenses I don't really see any point. I am seriously thinking to cancel my order. Do you really think that there are still chances for ROI? Any suggestions?

Thanks!

He has a good calculation and I as certainly many others would also like to see comments on it. Comments up to this point have focused on the genesisblock calculator. This calculation includes steps and a tapering growth rate.

The calculation looked ok.  The ROI drops off rapidly, but it still look like it's worth mining until you have about 40BTC then maybe sell the rig, or try and running it under clocked for more ROI.

Didnt KnC expect to ship 500TH in the first batch (supposedly september) ? If so, there is no way the next difficulty jump (after todays) would only be to 199,126,888. Even if everyone else stopped shipping, the network hashrate would be the current 1200 TH + KnC's 500TH  which gives a D of  ~240M instead of 200M. And I doubt BFL, Bitfury and others will stop shipping, in reality it will be above that, even after taking latency in to account.

Of course I dont expect every KnC customer to receive and deploy their miner next week either, but that only makes  it worse for those not getting their KnC gear in time.

Another thought is that the decreasing growth may not be incorrect over time, but in the coming months, I would expect the exact opposite. As KnC/Cointerra/Bitmine/whatever all receive their new chips over the course of ~2 months, I would expect to see a dramatic acceleration of the network growth compared to today. Perhaps early next year that will reverse, and the rate of growth may decrease (in %/day),  but surely not in the coming months which are crucial for the ROI of most current asic preorders.

Maybe is not a bad idea to sell it later. I could mine for one month and sell it with PSU. To the buyer it would be cheaper than the new units from KNC that will deliver in november for 5000 USD.
Thanks for the idea!

I also have the strong feeling that too much hashing power got sold in batch 1 - in case they deliver 2-3 Petas until mid Oct we see 500m+ diff soon. Doom for everyone...  Undecided

Are you sure you make that much coins in October that you can sell it with profit in November ?

Sorry, I doubt it, except their 'under promise - over delivery' turns out as 'margins upon margins upon margins' regarding ROI, since the delivery date could not be meant for sure.

Maybe there's a freebee for everyone?
They would make less profit but still more than enough for sure, with one huge difference: customers are getting ROI and will be happy/order again.

When KnC does not offer any kind of compensation in case things work out as worse as they currently look...I'm wondering who will buy gen2.
Ok, maybe through articles in economic magazines and their 'reseller' program they might find enough greedy persons wanting a 'money printing machine' and lack of knowledge about competition..

exactly

When selling miners you have in general three choices:

1) Sell a limited amount at a very high price
2) Sell as much as you can for a lower price
So customers are happy with their investment (making ROI).

3) Sell as many as you can at the highest price acceptable or even above it, which results in losses for buyers and max profit for you.

You are right - even option 3) is valid in a free market. No one forces people to buy. Still - As a responsible company, KnC must have anticipated their impact on the network somehow. I have the impression they did, but closed order books a few weeks too late imho.

I guess this is also the reason why we dont see canceled Oct batch orders on their page for sale - they realized it is better to hold 'em back...

In case they really sold & deliver 2-3 Petas until mid Oct we can hug them for beeing good engineers - but thats it... strategic/ responsible thinking = 0 - I would be very disappointed.

I made several investment scenarios. But 500m+ diff by mid/end of Oct beats even my worst case scenario by far - getting worried, so sad  Embarrassed

Like I've said in a few speculation threads (so far my diff projections have been almost spot on), I'm pretty sure we are only on the brink of rise. It will be vertical for quite awhile. It will plateau eventually, but people even with the large machines, will feel the struggle just to churn out what block erupters are doing today.

Ill grant you that, but I havent heard anyone refute hashfast's argument that the minimum estimate of KnC's die size based on the package/underfull dimensions would be on the order of 900mm³. Thats not just a little bit bigger, thats an epic size.

It's not the 28nm fetish-ing, it's just plain blindness when somebody claim that it is unimportant that your 28nm chip burns 60% more electricity per GH than your 55nm competitor (measured) and 100% more than the rest of the 28nm camp (expected). Only thing left is to jump to conclusion that everyone else is lying and to ask for Bitfury miner screenshots in disbelief. Yeah, it will surely be unimportant in march next year when every watt will be counted if your miner is plugged from the wall or not  Roll Eyes

Can those asics be down clocked in order to improve the W per GH/s significantly ?
I'm not aware of infos regading this or I might have missed it somehow.

1.6W per GH/s seems quite bad in long term, no?
If your competition is mining at 1Watt per GH/s or less,  then yes that's bad, as it means they can pump up the net hash until you can no longer afford to mine, and they still can, unless you can find cheaper electricity.



What I think that people don't realize is that by the time the cost of electricity comes into play, the network hash rate has made your device practically obsolete anyway.

Example. I live in the north east of the US with fairly high power costs - $0.20/kwh. It'll cost me around $114 or approximately 1 BTC at today's prices to run the unit. Presuming BTC/USD prices stay the same, by the time that it no longer produces 1 BTC per month I'm not going to be very interested in running my Jupiter and getting only 0.0009259% of the 3600 BTC mined per day.

$/Gh and timing of delivery matters far more than watts/Gh.

It's not the 28nm fetish-ing, it's just plain blindness when somebody claim that it is unimportant that your 28nm chip burns 60% more electricity per GH (unmeasured worst case prediction)than your 55nm competitor (measured) and 100% more than the rest of the 28nm camp (expected) (the only thing that is expected is that simulated best case results have never equalled the reality of Bitcoin mining ASICS, have they? So better to be responsible, and err upon the side of caution, as engineering over marketing dictates). Only thing left is to jump to conclusion that everyone else is lying and to ask for Bitfury miner screenshots in disbelief (if that's a dig at me, get your fact's straight. I never once claimed any disbelief, just requested video as the products are in the wild for a baseline comparison of w/Gh/s as people are so keen to draw comparisons once KnC's data is to hand. Again go and check who posted congrats to Punin about three posts after he announced the Bitfury boards were populated and complete; https://bitcointalk.org/index.php?topic=250249.msg2911187#msg2911187 Wink). Yeah, it will surely be unimportant in march next year when every watt will be counted if your miner is plugged from the wall or not  Roll Eyes (Perhaps, by that point you could always underclock kit, or move on to next gen - nothing lasts forever, especially at the rate at which Bitcoin mining tech is racing towards the smallest feasible die shrink, if the BTC price justifies a worthwhile investment)

Depends I'd say.

It depends one the environment: competitor's $ per GH/s, W per GH/s  as well as shipping date and total amount to be shipped
