I don't believe Sony is worried. More TFLOPS and more RAM bandwidth cost $$$. It seems to me Sony designed the Neo below the typical $400 barrier, giving what most of the people are asking for: 1080p - 60fps. 4K/UHD is raising but it isn't there. And still many people will prefer to save $100-150 and get the base model.
Because power did matter when the generation launched, there was the 1080p60fps dogma, but above that is useless for many. And I say this typing from a Retina display. If I could save 200€ getting a 1080p display instead of 1600p I would have been much happier.
