Re: BFL - Update 3/4

This whole testing fiasco is really a wonderment. To lose that many precious (and expensive) chips to only gain a marginal amount of useful information is insane. At any company I have worked for that kind of decision would have landed someone a pink slip.

To be fair, the cost of a processed 65nm wafer is likely somewhere between $1500-$2000. Not exactly a fortune.

Avalon pays (it is estimated) about 4k per wafer at 110nm.

How is BFL paying half that at 65nm? Somehow your estimates sounds kinda off.

How many chips per wafer does Avalon get?

I don't recall. I think it may have been 4,000 chips per wafer. I only recall that the die size is 7x7mm while BFL's is 15x15.

I believe Avalon's die size is 4x4 and the packaged QFN size is 7x7, but I don't feel like looking it up. I might have ASICMiner's die size instead, but either way the actual die size will be less than 7x7.
