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...

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.

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

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.

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.

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....

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

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.

Didn't the "we aren't mining on public pools" statement stem more from people accusing BFL of having the equipment ready to ship but they were using it for their personal mining instead? Of course they should do some testing/demos on actual public pools, those are the pools customers will be connecting to.

No, they said they were only going to test on a testnet of some sort. No live mining. But they said a lot of things.

If you listen to all the video you will hear that the PCB is still under development, so probably even more power down.

All this Avalon promoting is great, but how many of you actually have an Avalon in your household?

I do.

You can't compare the wattage on a BFL with an Avalon. An Avalon is a self-contained mining device. Add in the wattage for the laptop and the BFL is less efficient than an Avalon! ROFLMAO.

You are probably wrong in a couple of asumptions. For starters you can use something smaller than a laptop, eg. a Raspberry Pi. Secondly you only need the one to talk to the 5GHs, 25GHs, or 50Ghs products, at the high end power consumption the controlling computer becomes insignificant.

That's not what the demo showed, now was it? They showed the power draw minus the computer, which is not a fair comparison to a complete Avalon.

Details details.

The "Tethered wattage" problem...

-------------------------

I am sure the demo guy can just turn off the laptop and save a few watts in the calculation....er...wait....

Avalon > BFL perhaps, but BFL is in my budget and Avalon isn't even close.

Air costs less to produce. Substance is expensive.

Yeah, it seems with the increased power usage comes increased heat, so now what was supposed to be a coffee warmer needs to be actively cooled with fans, and gets put in a larger case.

And did you hear the fan/s in the video? I wonder what the larger 60 GH device will sound like. I was really looking forward to the silence that the ASICs were supposed to bring. Oh well.

For those that don't know, the Butterfly Labs symbol is an envisioning of Josh's super collider experiments.

Whats the point of all this comparison? Don't think there's a dispute that anyone here would want a Avalon over bfl at this point is there(since there is no bfl shipped yet)? At current difficulty no one cares about power consumption or original cost/hash. So again wtf is hte poitn of this comparison. Take this up in like 6 months. Then you can compare both till your excel sheets are fucking REF'ed out.
