In order to avoid and resolve such questions, we send our equipment to dogie. Recently we have shipped him an Apollo (you can read his review and specs here
https://bitcointalk.org/index.php?topic=881295). Next, we will send an Ares. And after the Ares the Zeus is planned to be sent. Generally, dogie's reviews are very thorough, so I hope you will be able to find answers to all your questions there.
If you'd like, I'd be willing to compensate any lost income you might suffer from the negative trust between now and a proper review by giving you an escrowed bet up to 100BTC.
I will bet 1:1 that you will not be able to provide a PCB with a single GN1 asic that simultaneously achieves 810GH/s (that is your spec, -10%) and drawing 0.78J/GH at the wall (your spec + 20%).
If you want even further relaxed specs vs what you claim, I will alternately bet you 1:2 (my 100 vs your 200) that you cannot provide a PCB with a single GN1 asic that simultaneously hashes at 710GH/s (20% below your spec) while drawing less than 0.91J/GH at the wall (your spec +40%).
Given the sums involved, the bet of course would need to be escrowed. In addition to the unit you send to dogie, I would like to purchase one board to be sent at the same time for my own verification. If you're unable to provide a full unit, I'd offer to pay 1/5th the price ($600) for the single board. The purchase would also be escrowed, and should the board fail to meet the relaxed spec (710GH/s @ 646.1W) the escrow will be returned to me and I will ship the board back to you at your cost as it is obviously defective.
Let me know if you're interested, and we can flush out and finalize terms.
