The new website is looking awesome! Unfortunately I don't have time to move the database and migrate everything over tonight.

I will finish this in the morning..


However I have posted some specs to the old web site as promised.

The only thing that is really missing is the energy efficiency information which right now I only have simulated data.

I have stated before I will not claim any simulated/estimated electrical efficiency data and I am sticking to that - however...

I have decided to ask a reputable, well known and impartial third party to conduct a simulation and post the data for all to see.

I will try to have this arranged and completed this week so you still have a reason to check out the new web site! Tongue


After I post the winner on the contest thread I'm gone to bed - be working regular business hours tomorrow

have a wonderful evening and remember pre-sales end 24 hours from now!

Thank you to everyone!

Tom

It says on your product specs page that you are using 90nm ASIC. Is this the final spec or is it only for the prototypes? (dumb question I know, but I have to ask it)

So far you seem to have the smallest process node of the 3 ASIC companies if so.

Can you tell us more about the power supply? What do we have to buy?

My anger against what is wrong in the Bitcoin community is productive:

Here are the changes I see for the $1070 unit:

Was: Multiple SHA256 hashing cores for a total Bitcoin mining speed of 54Gh/s
Now: Two Bitcoin SHA-256 Hashing Clusters with Twelve 90nm ASICs (6 ASICs per cluster)

Was: Thermal sensors and on chip heat sinks
Now: Dual High Performance heat sinks and fans.

Was: DC barrel connector for power
Now: Optional 4 Pin molex or DC barrel connector for power

Was: Compact board design allows easy stacking and cooling
Now: Board dimensions 4" x 9"

Was: bASIC Mining boards are projected to ship in November/December of 2012
Now: bASIC Mining boards are projected to ship in December of 2012

New: 54Gh/s is the gauranteed minimal hashing speed - we were very conservative here and it's likely that our software development team will be able to increase the mining speed.
New: Energy efficiency information is coming soon.

90nm... my wild guess is ~2 W/GH.

Excellent, thanks for the info, Tom.  It's good to see some solid info.

This looks like it might be a likely candidate for the chip if it's sASIC: http://www.easic.com/low-cost-power-fpga-nre-asic-90nm-easic-nextreme/easic-nextreme-overview/

Can you tell us more about the power supply? What do we have to buy?

With this new info, it makes it a bit easier to guess at his power, though it's still speculation.  I'd estimate somewhere around 200w for a 54 GH/s unit, if he's using a CBIC.  If it's an sASIC, it would likely be more.

If you're searching these lines for a point, you've probably missed it.  There was never anything there in the first place.

90 nm gate size seems reasonable. However I doubt much from just simulation data (own simulation or 3rd party simulation) until entire prototypes are made and tested. There is a reason the guys making the avalon say their simulation results show 2-2.67 watt per gh/s but give an estimate of 600 W because of their past experience in device fab.

I await actual efficiency data (from all companies), but remain confident that Tom has created a competitive product.

How do you know what process BFL is using?
Based on what different companies have said. (Avalon and bASIC)

Avalon has stated they are aiming for 130nm to 110nm.
bASIC has stated they will be using 90nm.
BFL has not yet gone on the record as to what process node they will be using.

So logically, up to this date, bASIC is using the smallest process node based on publicly available information.

Open source firmware!  Will BFL have that as well?  I'd love to be able to compile my own firmware, voiding the warranty, of course (it's not like we're not voiding warranties on our GPUs all the time).

Thanks Tom!

There's only speculations regarding the watts, we should just wait another week or so for valid data.

Tom, do you have any decision about European customers ? I don't want to leak anything but it should be nice if you've managed to sort anything in Europe Grin

Will it be an 5-10% increase or more or ? Can you please add this info along with power consumption ?

Thanks for the board size (4"x9"), can you tell us the height of the hardware?
I will install the miner in 19" cases with 4HE, so the height is important for me.  Wink

Is there anything special for EU customers? You only have to pay VAT and some import fees depending on country (for me is 20% VAT + up to 5% import fee), thats all. Am I missing something?

That would be even more speculative than estimated power consumption Smiley

I hope you do this as I'm pretty sure he edited a post earlier in this thread, although I have no proof. Apparently he has issues with this in the past...

Yep, there it is.  I love when people accuse me of this, because you look like such a dolt when I explain that you can see when a post was edited last if you use the default forum skin... and just like the last dolt who accused me of this, you are also full of so much fail. Sad

I was wondering why I couldn't see edits when I was using the default forum skin, but I didn't have time until tonight to figure it out.

Do not use the Forum or Board Default, which is what 67k people are using.  That is the Bitcoin Theme without last edits.  Use the SMF Default Theme - Core, which is the default theme that came with the forum software.  Only 30 people are using this theme.
