I doubt they had gotten trough batch 0 without all the refunds however, seems to be some terrible early yields for 20nm :/
Yeah, I surely expected a higher hashrate than around 680-700Gh/s per asic(3500Gh/s /5)
but its still above and beyond the 150Gh/s average on the 28nm Jupiter series asics.(600Gh/s /4)
So a single 20nm Neppie asic actually hashes faster than an entire Jupiter! (4-----28nm's)
So I'm not really going to agree with "Terrible early yields" just because our dreams of a 6th/s Neptune didn't come true...
The 20nm asic is pretty good actually imho... but who else has another 20nm asic to compare it to? Nobody!
Oh Wait!!! We'll have double Neppie deal 6Th/s per order at least (someday)... lol
