Almost every single ASIC manufacturer to date has missed their published power targets. I do think Spondoolies has done a great job so far, so don't get me wrong, but caveat emptor when you're buying a non-refundable product that doesn't even exist yet.
The Neptune looked like a great buy back in November, and we all know how that turned out, so don't count your chickens before they hatch.
Also, the competition doesn't stand still, and new companies like Spondoolies pop up out of no where from time to time, so it's impossible to predict what the market will look like in August.
One month in Bitcoinland is like one year in many other industries.
How can you compare Neptune which is on 20nm node and a totally new chip with the Spondoolies RockerBox chips which is on 28nm and just a die shrink using Tick-Tock strategy from the best 40nm chip that is hashing since March? Also don't compare the
lousy support from
KnC which holds my refund for almost 3 weeks while they are mining 300k$ per day.
