BFL 5 GH/s Miner Demo

[Dexter770221]

What is efficiency of 1250W power supply when it delivers only 3% of maximum load?
Below 50%. Kill-A-Watt shows 36W so  power draw of the unit alone is propably 20W. With 25W power supply it should be able to see that kind of figures.
Just saying....

[mrb]

5.3 GH/s @ 36 watts + 20 watts for laptop = 10.6 watts/ghps
68 GH/s @ 620 watts = 9.1 watts/ghps
Efficiency: Avalon

That is an unfair comparison. Drive the Single with a 5-10W mini-computer board similar to the TP-LINK in Avalon (instead of a 20W laptop), and the BFL solution becomes more efficient than Avalon.

Yea it would be far below 50% most likely, i bet someone can find the power efficiency curve by looking up the model used

EDIT:
Quick googling yielded no tests for below 330W.
But assuming it's even 70% at practically idle the unit is then drawing 22.6W

4/16 "There's plenty of doubt, it has nothing to do with us. It's probably someone relaying blocks through EMC I would imagine. BFL is not mining on the live network."

Somebody forgot to switch pools....

You're confusing the supposed large-scale mining conspiracy with a single fucking 5GH/s demo unit. A one minute video demo is not what any serious miner would consider to be "mining".

Here's a pro-tip: if they were running a secret mining operation, then they wouldn't be running it from that laptop.

Exactly. Looks like another lie from BFL. BUSTED!!

You butthurt pre-orderers are really scraping the bottom of the barrel to find more reasons to hate them.

5.3 GH/s @ 36 watts + 20 watts for laptop = 10.6 watts/ghps
68 GH/s @ 620 watts = 9.1 watts/ghps
Efficiency: Avalon

5.3 GH/s @ $149 = $28/ghps
68 GH/s @ $1500 = $22/ghps
Price: Avalon

June 2012 -> May+++ 2013 = 11+++ months
Sep 2012 -> Apr 2013 = 7 months
Time to market: Avalon

Triple crown goes to: Avalon!

What the fuck. The low end unit was never intended to compete with Avalon. Their fucked 50 or 60 gh/s singles should be using around 200-400 watts. Add in a raspberry pi and it's still way less than Avalon.

5.3 GH/s @ $149 = $28/ghps

It actually costs $274.

They are comparing the historic prices of BFL and Avalon. If you're going to use the current price for the BFL unit then you must do the same for the Avalon, which is more than $10000 at current prices.

New ASIC machines will show before the BFLs due to chips entering the market. Power consumption argument that BFL beats everything isn't legit. First, it draws the same on that small mutant machine as avalon, the other machines still don't exist, and there are parts of the world where even GPU mining will never go away due to cheap electricity. It'll always bring fair profit in fiat terms.

People who have fallen for the asic 65nm technology just because it draws less than 110nm didn't do the math correctly.

BFL     
32watts/5.3GHs= 6.03watts/GHs

Avalon 
620watts/66GHs= 9.39watts/GHs

Is that the "same" I think not. What part of the math needs doing correctly again?

the part of math which bfl potential customers missed is that 110nm makes money for the last 3 months and that it didn't put GPU rigs out of the game...

What about the statement that this coffee warmer would run from USB Power?....

Well, when it will ship, we would already have USB 5.0, which has power output 50W

the big problem that came out these days is da power supply.
5 gh's is using about 36w, how much will be using a 1500 gh's?
a normal power supply wont be able to keep it workin, you'll need to set up a huge supply for that stuff

minirig product design is apparently abandoned, 3.5kw per one household switch is max.

looks like 3.5kw wont be enough to run 1500 gh's, at least i hope so

Someone calculated it to aprox. 8 kw/h.....

Exactly, and BFL said on their latest version of website that it's out of stock... Another lie...

if u got a nuclear power station at home it wont be a big problem

The guy is obviously just trolling, you can tell by the repeated misquote of the 32watt BFL power consumption, best to ignore him. There is half the guts of a laptop in the Avalon, like TP-LINK, spartan 6, Ethernet, USB, FTDI, WiFi, there is no reason why you can't use similar bit's to control the BFL unit, nobody says you need a laptop!

Even though the Avalon is old 110nm technology, if someone put up an online shop the Avalon ASIC powered boards for sale when the chips have shipped and Avalon has published their PCB design, I will buy some for the heck of it. Same goes, if I hear factual reports of the BFL units being delivered and reviewed I will order one or two. Both technologies are great compared to GPU mining.

the good thing with the abandoned minirigs is that there will be available cases for single and mini single assembly.

Lol, yeah. I'd take mine in a mini rig case. It might even fit two or three... ;-)

That much waiting time for a coffee warmer and i will still drink my coffee cold?
  I want my money back

if u got a pre-order for a 5 gh's we can trade about it
