HashFast announces specs for new ASIC: 400GH/s

[raskul]

Yes small cooler chips are more efficient for sure, but bigger chips that get alot more power per chip are cheaper.

You're confusing size with density. "GH per chip" is size. "GH per mm^2" is density. Density means you get more hashrate per wafer. Size of the chip is meaningless.

The amount of GH per Wafer has a direct affect on the GH per chip which goes into the price of a chip and eventually into the price of a unit.

If you have 1 wafer that can make 100 chips and each chip is 10gh or 1 wafer for 100 chips and each chip at lets say 50gh, the second chip you have a better shot at turning a profit on.

In your comparison all that matters is that one wafer has 1000 gh/s and one has 5000 gh/s.

Using big chips is only detrimental because it requires $150 worth of watercooling for each chip compared to small chips which require ~$20 worth of extruded aluminum per KW for cooling.

You don't need watercooling if you are using AM's immersion cooling.  Big hot chips like HF's are perfect for Novec.

Many small chips require many more components, raising the total device cost and chance of failure.

If AM doesn't buy HF's 16nm design and stick 100,000 of them in datatanks ASAP, they will be crushed by KnC, BitFury, and Cointerra before the next block reward halving.

i think a helluva lot of due diligence is going to have to be done regarding those chips.
I doubt it's as clear cut as you think it might be. interesting to know who does finally buy the rights tho... interesting times indeed.

I would have to agree, water cooling does cost alot more then air cooling but I am sure it is possible to aircool a hashfast chip. It might only run at 200gh but it might be possible.

Relating to immersion cooling,  I am not sure what the price of setting it up is, but I am sure it is more efficient then water cooling. If anyone gets bored and wants to try immersion cooling a hashfast board id gladly tip you a bit to get details on what happened.

Again you're completely wrong. Let's look at the number of components on a HF board.



That's a hell of a lot of components (many of them very expensive).

Compared to something like an Antminer:



Very few components (all inexpensive).

personally I think that has to do with hashfast not designing the board correctly. I am sure a cheaper board could be produced.

No, but now you're seeing the fatal design flaw with designing big fat hot chips. It's extremely hard and expensive to provide adequate power and cooling to big fat hot chips.

"Fastest bitcoin chip" is like having the "biggest gas guzzler". It's not a good thing.

I think there are two key factors to consider when comparing mining systems/chips.  1) system dollars per GH.  This is where big hot chips like Hashfast run into trouble.  The cost (expensive board, big power supply, water cooling) makes scaling a mine too expensive.  2) system power (at the wall) per GH is also a factor as we all pay for power.  The lowest I have heard HF do is about 0.90w/GH at a low hashrate 320 GH/s.  There are lots of small chip systems that beat the crap out of this system power per GH.  So small chips is the way to go for both cost and power.

The power numbers are wrong there. It's a Habanero as opposed to a Hashfast board, but it's running 405GH/s poolside on a 60 minute average (not what cgminer is reporting) and it's pulling 341W from the wall (including cooling) using a $40 850W HEC silver rated PSU.

It's no use trying to explain things to Syke rationally.  He is in an emotional snit, suffering great butthurt, and in no mood to concede one nm to your mean old facts and logic.

Let's hope HF's market-leading GH per wafer IP fetches a great price at the auction, so Skye will get his refund and stop being so grumpy and obtuse.   

Yes! Personal attacks are always better than reasonable and on subject replies. Here are some other generic replies which you can use in the future: "You have a small dick", "You are stupid" etc.

Good point Syke. Bigger isn't always better.

Any idea how much the cooling is using?

I know that hashfast babyjet boards are not that efficient. I measured mine originally with the water cooling and got about 450watts.

The same model of cooler (though a physically different one) pulls 0.725A at 12.1V, so 8.77W. At the wall, probably pretty close to 10W of that is cooling.

[digitalbrass]

I have no intrest in mining anything anymore, where is our refunds.

[defcon23]

what refund ? what did you expect ? lol    mpp's ? 

[Legend21]

So guys tell me honestly, how much % we will get back minimum from our refund, in my mind i already know it would be fcking 0- 10%. But tell me your opiniuns.

Also is 4 december 2014 the only date when teh assets of hashfast will be sold? And will all the assets be sold and liquidated? Or is there a continue date for next auctions if the assets will not be sold?

Is it after 4 december 2014 finally done?

[raskul]

i very much doubt we will get ANY % of our money back. i've resigned it to history a long while ago.

In the list of priorities, the customers of Hashfast will be the last in line

First to take most of the available money are going to be the lawyers involved, the liquidator, the temp CEO, etc...

Then the people employed full time at an increased salary at Hashfast

Then the government, social security, ...

Then the banks

And then the customers

If you have a missing order, you might get something
If you are waiting for MPP, you'll get laughed at.

Any more questions? :-)

[Legend21]

Then lets put Simon Barber 80 jears in jail.   Its my money worth

[aasl]

is there any document stating how the revenue of the auction will be distributed?

[MrTeal]

Is anyone here planning on going to the auction?

[starsoccer9]

Is anyone here planning on going to the auction?

I am not, but am considering sending in a bid via email. I dont have much to loose. Best case I win something cheap. Worst case I loose and get nothing.

[duncwa]

Went to attend the HashFast auction only to find that there was no auction or it had been moved to another location.  My bid was denied as not qualified.
