I welcome anyone who can actually ship product!

That said, am I getting my math wrong or is the $500 per chip, capable of 20GH/s to 40GH/s, a might bit more expansive than the BitFurys at 2GH/s for $25? If BitFury was double cost, it could be equivalent to these and you already have an IC for them? Yes, you could order a larger quantity and get it down to $4.50/GH/s but that still leaves alot of room for the BitFury's to cost more and still be cost effective.

I don't remember the the GH/W of the BitFury's though, and that's the dominating cost if you mine for awhile. I think the BitFury's were around 2W/chip? Which would make them 1W/GH right? These claim somewhere between 0.6 W/GH to 1 W/GH (unless you undervolt them). So I guess these would win out should you keep them mining for long enough.

Actually its only $100 per a chip, $50000 for 500 chips. That makes it $5 per a gh/s at 20gh/s and $2.50 per a gh/s at 40gh/s. Pretty inexpensive really. A bitfury chip is $25 per 2.7gh/s which makes it $9.26 per a gh/s, significantly more expensive than these chips. These chips and the bitfury designs also use similar amounts of power per a gh/s, with a slight edge to the coincraft asic.

It's a shame that Hashfast isn't offering chips, these chips could be good. Hashfast's small batch sizes are probably actually good for bitcoin mining as a whole, however. By keeping down the hashrate they flood the market with, they keep their devices more profitable.

It may be a terrible thought, but personally I hope that any asics I do not purchase are slow to market or vaporware. It is shaping up to be quite a bumping ride in the overall hashrate with VMC, coincraft, and avalon v.2 being announced, not to mention KnC appears to be shipping in astronomical quantity. BFL has possibly sold 3PH/s of asics, who knows if they will even deliver this. The quick reselling of another batch of KnC could very well flood the market beyond profit for even their customers. For every asic they sell, they devalue the other asics they have already sold. I was slightly worried before, but now I really feel we may have an astronomical hashrate by January. I would even go so far as to claim a lack of intelligence in the planning of asic designers, as this flooding of hash power does not seem like it will end well. While it makes me sad to say this, I really hope a few of these manufacturers fail to bring chips to market.
