Very impressive. Also very necessary once all those 600 Ghash/sec miners come online in the next 30-60 days. The difficulty will go through the roof. I wonder what it costs to build a 10 chip board. Single chip 2.5Mhash/sec bitfury chip board originally cost $100

Aside from the ASICs themselves? Cheap, if he can get a large board run together. The real questions are, how much for the ASICs, and are you capable of mounting BGA.

  Looks like 500 for 6 BTC. Like $14. I wonder if anyone would want to put together a batch order?

    where do you see that?

    One place where to organize this would perhaps be the project's Wiki.

    Those are the old 55nm chips. There are 28nm chips now.

      Avalon gen1 is 110nm. The (new) Avalon gen2 is 55nm. KnCMiner is the only competitor who has 28nm chips, but their chips are merely 1000 Mhash/Joule, which is a power efficiency pretty close to Avalon gen2: 730 Mhash/Joule.

  No BGAs, I think you might be seeing the crazy thermal via arrays under the chips (I went a little overboard, the next revision will likely have a couple less vias on each chip). The hashing ICs are QFN. This would be a really easy board to manufacture. Low unique part count. I just need to move the decoupling cap vias out of pad and it'll be ready.
