No idea since sp30 does not exist yet (neptune might not either)

However knc has completely stopped caring about customers so I would never support them.

Also 0.7w/gh is quite a fail for a 20nm chip.

Point is that making comparisons based on magic crystal ball readings is pointless.

I still think sp30 will be a badass machine but I'd still never preorder one (not that I can afford it).
