Hi,

I am a newbie in the BTC world and I was wondering what would be the feasibility of an fpga based hardware with these specs:

     900Mhashes/sec

     about 5 watt power consumption

     $1300-$1500 unit price

Do you know how to make one with these specs and this price?

Hi. I'm also new to the BTC world, but I'm an electrical engineer and I've been following the threads on FPGA mining recently. I think that for that hash rate, your power target is off by about a factor of 25 and your price target is off by at least a factor of 2.

Disclaimer: I have not yet built, designed, used or measured an FPGA based mining rig. If one of the experienced FPGA miners drops in here, they may be able to provide a more accurate estimation. Maybe I'll play around with FPGA mining myself sometime, if I don't get distracted by a shiny object first. Wink

i think someone need start organizing people to start building these FPGA,s rigs soon. the first group to create them and start selling can earn tons of money with.

well what are fpga's worth for if they consume 5*25=125 watt?? it may rise upto 10 watt but not more....

I can design the system with above specs but i really need to know if such a system is feasible....

How can you know it's feasibility without a design?  I think you should try to design it... See what you can come up with.  I'll test it for you Smiley

sorry, i wasn't talking about design feasibility, rather the market feasibility... what any designer would need to know is the worth of his effort... if i develop a system and people still prefer GPU's over fpga rigs, then why would i want to waste my time?... in short if i could such a system in the market, how many people would want to buy it?

Double check your numbers for 5W and 900 Mhashes/sec...  If you still can produce at these specs, you'd have lots of interest...

well. now you only can bitcoin mining with gpu coz is the only comercial option. im bet if someone invest in stand alone or especialized external units with good specs you can earn a lot in the short place. considering the dificulty jumps and energy cost any miner with a calc find these especs very interesting. even if you cuad these energy consumption rate.

GPU is not the only option.  People are already mining on FPGUs.

My FPGA design can do 1GH/s on Stratix IV 530.  The dev board costs USD$8k, and would need fan/heatsink added.  I'm guessing that power usage would be around 40-50W?

Is it stand alone? or a computer is required?
Usually the designing software could provide the power requirements of a system, try checking that..

What do the costs look like for a higher production?
