How will he get/cool 1700MW? How many chips are needed for 1300Th? And only 1.3 mil $ for more than 50% of current network? How come nobody else noticed these points?
Ken stated that the chips are rated at 1,9 GH/s and that the estimated yield per wafer is 6,800 chips.
If he wants to deploy 1,292,000 GH/s, then he needs (/1,9 GH/s)
680,000 chips or 100 wafers.
Cost per chip is $1,338,000 (total) / 680,000 chips =
$1.97Edit: Also, at 2.5W/Chip the
total power consumption is 680,000 * 2.5W =
1,700,000W or 1.7MWRoadStress, your math does indeed suck.
