.... and there are 4 of them on a motherboard.

Why 4? Not 8?
There's an end somwhere. In real world it will be power or price before performance. Why? Performance scales lineary, power and price does not...
As I said, ratios counts most. If you hit power limits in performane/power ratio then you can do nothing. If you change that ratio to 6/2 then you can increase performane 3 times...

That is the point, you do hit a limit in performance/power ratio, it's Voltage squared, so
1V^ =1 and 0.5V^=0.25, 1/0.25=4/1=8/2 minus static power, minus supporting electronics = 6/2 to 4/2
1V^ =1 and 0.6V^=0.36, 1/0.36=~3/1=6/2 minus static power, minus supporting electronics = 4/2 to 3/2

You can buy ASICMINER USB powered stick with 300MH/s performance.
When bitfury will release his chips you will be able to build 5GH/s USB powered stick.
Which one will be giving you more profits?

Someone hurry with the PCB schemes and let's start getting some nice USB miners.

5GH single in spec USB port stick in 55nm (implies powered only via one USB port that most computers have) is BS, besides all other tech problems how are you going to cool 2.5-4.5W+, and if you need external cooling when room temp is regular 30C/86F then you made bad design, are you going to put fan in USB stick?

And if it would be possible then it will also be possible to run it at normal 1V voltage and get double the performance 10GH via normal power supply - if anyone is smart they will choose that and not a USB toy.

A bit early to tell, but I think my first order of wafers is going to be 30 PetaHash = 30,000,000 GH, by the end of next year it certainly be in 1,000 PH range, god only know what Knc/Kcn will come up with

How much total power do You need for the 30 / 1000 PH ? Where do You think You can get this power ?
Most data centers I know are limited by power.

...

Currently ~100 MWatt is used for BTC mining [assuming only GPU exists and there are no FPGA and ASIC miners]. Powering 1000 PH with this would be difficult (impossible now, but possible with low voltage 28nm ASIC).

Is Bitfury going to sell his chips directly to the public? I thought he was supplying chips only to 100TH and MetaBank.

maybe only at start wait and see

30PH would use 60-125MWh, I would not be running it all for my customers, they will be running most of it themselves.

Sabey B1,B3 77 MWh each, and they have more sites and there many more companies

US electricity use for data centers from the EPA report to Congress ~90,000,000 MWh in 2012

"198 megawatts of power."
"Microsoft (MSFT) will invest $500 million in the new data center in the Chicago suburb of Northlake, Ill."

You want to spend that much ? :-)

Well they will have to think of something, all that hashrate centralised to one owner will not be healthy for Bitcoin. Having all that hashrate located in one country, especially the US will definitely not be healthy to Bitcoin! All it would take is for yourself to be penalised by a government with an assumed valid reason and that could be 30 Petahash taken off line in one foul swoop.

I hope you are not seriously going to try and handle all that hashrate yourself, and in one undistributed location (even one country)...

I don't have to, DC spends that as capital project for 10-50years, I only spend $0.13kWh including cooling, racks, internet, generator backup

Of course not on both.

Good man!

He will just end up using more chips and more electronic components and PCB to get to the same performance and since power use by any ASICs is already very low and cost per kW is not $4 but only $0.10-$0.40, there is no point in ruining chips at low power.

How do You get $0.1 ($0.4) per Watt ?

Residential rate in New York is $0.34kW, commercial rates in some places in US are $0.08kW

Bitfury was talking about hardware cost per 1 Watt ($4 per Watt).

Where was he talking about hardware cost per W?

I was talking about different $4, at $4kW (which is 10-20X more than anyone pays) profitability shift from running your chips at standard voltage to running them in low voltage. But, since no one pays $4kW profitability is on standard voltage.

[tytus]

but You forget the cost of other components on the board. You can pay $4 per Watt in hardware. If You account for this , having a low power chip generates significant additional cost savings.
