wouldn't be more accurate to compare by square millimeters of silicium ? number of transistors ?
GH/s/Watt maybe ?
no ASIC is 6 PTH/s ... you are talking of a device with many ICs ...(integrated Circuit)
That number is 6TH/s, not 6PH/s. Think you might have read it wrong.
yep, my bad 10^12 is tera not peta ...
