Yes on the OP.

You should go read the threads on the litecoin forum. The competitor is not really competition.

Your competitor just announced their prices. It's like 8000 USD for 25 MH/s.

caught my attention! is there an estimate of how much hashing power these will have per unit yet?

Looks like they rally got a jump start.

Q1/Q2. Then we will move them to our hosted facility after testing.

When do you expect production to be complete for hosted mining, Q1, Q2 or later?

The fun is only beginning, the ASIC will only lead to many other related projects we have in the works or completed and waiting on the launch. Scrypt and crypto in general should have an excellent year.

i have 4600khps with 1.8kw 6x HIS 280x not X² one.

@jasinlee - I've been watching this thread for some.
Looking forward to buy some Fibonacci SCRYPT miners as I've not been mining SCRYPT coins for over 10 months.... eagerly waiting.

Merry Christmas to all.

the exact cgminer settings are a BIG factor, so maybe he is not getting max out like 750kHs on a 7970

850w on 5 gpus, geez that is going to get toasted.

Are you running the GPUs at a facility on the side or at a business that doesn't mind? Running a larger number of GPUs and not being concerned by potentially more efficient options is annoying - but big-up to you if you are doing it and not picking up the power tab!

currently running 5 gpus with 850w power supply, and it has been a few months.

No, you do not. You need 900W to 1KW for 4 undervolted 4x 280x if you KNOW PSU's. It's just that nobody really does. A basic 650W Corsair VS can handle a 7970, a 6950 and a 7870. Is this "shoehorning" recommended for the average gamer/user/miner? Of course not!

Be sure to take your sweet time getting these created/rolled out.  My GPU's are and have been killing!

Technically it should but we have not tried yet.

Since I didn't get an answer yet, I repeat my question:

1. Are your ASIC estimates scaled up estimates based on real measurements of smaller prototypes or is it purely theoretical at this point?

They are scaled up estimates based upon the Stratix V pictured in the OP.

2. How did you get to the Altera FPGA estimates?

Timing analysis. We also benchmarked out miner against the open source miner kramble supplied and came to the conclusion that it is faster and requires less silicone area. This is mainly because we share some operations between cores. Krambles work is in another section of this forum, it is tested, proven and well documented. I would recommend using it to other companies too.

3. I could imagine you develop on FPGA's first to put the design into (digital) ASIC later or something, is this how your engineers went about?

FPGA mining could not go below 1.5$ per khs, we completed our FPGA miner, if you do not buy en masse then that figure goes to 4$ / khs. I do not think anyone would buy that.
We considered using Artix 7, but it only supports DDR3 400MHz, this made it unusable.

4. Why Altera FPGA's as a comparison and not one of the many other brands? Have you considered significant differences (advantage/disadvantage) of implementing on other FPGA brands?

There is no difference between Artix 7 and Cyclone V FPGAs for cheap FPGA miners and Virtex 7 and Stratix V FPGAs for ASIC prototyping. And we have one of Altera's field application engineers on our team, so device choice was straightforward.

5. Since in this business time-to-market is very important, why don't you go for FPGA implementations at first? Isn't the development time for FPGA based designs much shorter?

Yes, and we have them done already. But the $/khs is not practical. Unless you are using aftermarket FPGAs or own the facilities, there is little point in producing hundreds or thousands of FPGAs no one will buy.

Nope, we will be handling sales through our website which will be working on a shares type system for the checkout (too complicated to explain) but it wont do both at once.
