with the length of BFL's que...
I'm Just hopin' 

I am not ready to release this information .... just yet but very soon.


We actually have a new web site being designed right now and with it's launch we are going to launch some more info, specs, pictures etc

for now let me just say there are more chips than just 1 and 2

But don't worry this will all be public information soon.

Tom,

Can I ask a couple of simple questions.

1. The 27g is one chip? The 54 is 2 chips? On the same board.
2. If this is the case, what is the max number of chips you could put on a board, and what would be power drain? Has possible designers for 4, 8 or 16 chips on one board been considered?

Phil

Ok, I will not say for sure. But if I was to make an educated guess about ordering from either company today I would still lean the same direction.
I also ordered from BFL within an hour or so of the announcement and I'm beginning to think that I won't receive that order before my bASIC order. Just sayin'

Placed my order a couple days ago for the 54gh. Hopefully all goes well and the units ship out by nov/dec.

hi cablepair,

i sent you a PM regarding if i order a 2nd unit, can i combine it with my 1st order to save on shipping, or will i have to place a whole new order?

Any luck and we will have power specs verified and published in a few weeks by my software development team

i ordered two 54gh devices - one of them weeks ago . If power specs will be announced its time to talk about serious business 

Just bought a 27 to go with my 54. Will be really interesting to see what happens to bitcoin. X fingers it is in my favour .

LOL

how big's your dictionary file?

There is a serious need for this when law enforcement chooses to prosecute.

he's doing one each week it seems over the next 3 weeks if I read correctly.  https://bitcointalksearch.org/topic/m.1236393

It depends whether it's really worth it or not...  NEON scrypt mining on ARM processors was no more power efficiency than GPU mining.  GPUs have fast SPU clock rates and extremely fast memory, you may build an FPGA with ~300 integer units (eg spartan 6) hashing at 150MHz with DDR2 RAM only to discover that kh/s/w is not any higher than on GPUs.

At best with ASICs of scrypt I would suspect you would get an order of magnitude in speedup, probably less.  FPGAs then would be even worse, and aside from that refining BTC ASICs in the future will probably be more profitable anyway.

Scrypt hashing circuits are about the same size as SHA256 hashing circuits in terms of gate size.  I would suspect that if you could somehow make an ASIC comparable to that of the SHA256 ones with GDDR5 you would be able to hash scrypt significantly faster than and with less power than on GPUs, but the problem is that GDDR5 is expensive and so is the bus/interconnect.  Additionally the amount of memory required per the amount of scrypt cores scales linearly as per the current algorithm, so if you make a chip with 20,000 scrypt circuits you will need to initialize 6-20GB of GDDR5 memory, which is expensive.  Using slower memory and slower cores, as is possible right now with ASICs, will probably yield poor performance (GPU memory and GPU core speeds are an order of magnitude faster than DDR2 memory and typical ASIC core speeds).

In short scrypt ASIC producers may end up competing with GPU producers, which would be a losing battle for the ASIC producers.

If I order 3 54G/s bAsic now. Will I receive them in 2012 for sure?

Man that entry period was short.   

Cutoff in a couple hours?!?

Not all of us can be at the computer 24/7.

I want in!!

Maybe that's the project - making a new board for your modules to plug into... that allow them to scrypt.

Then you could at least offer that as an 'alt-grade' for close to cost.

Admittedly, I do not own a MMQ but how about re-purposing MMQs for Monte Carlo calculations?

Also, I am not knowledgeable about FPGA hardware, so perhaps someone else can chime in about the limitations of the MMQ toward this purpose.

A couple of random examples of FPGAs used for Monte Carlo calculations:

yes he is right, as far as I know - no current FPGA Bitcoin mining device is capable of mining scrypt alt-coins

You would get it faster? We dont know about that yet....
The ASIC world aint established fully. We dont know when BFL, BTCFPGA, or any other company is REALLY shipping.
Or are you implying once regular production begins, the preorders will be filled much faster than BFL would be...meaning normal orders would be shipped much sooner than BFL's normal orders?
That would for sure be interesting.
