Doing nothing between timeslices?
May be, I am taking you more seriously than you deserve?
Or your way of thinking and expressing thoughts is just to different from mine?

IMHO, it's bloody obvious than if KNL has any chance at all to be competitive against "normal" Xeon on non-HPC loads then it's *only* when there is a lot of parallel tasks ready all the time. *Much* more tasks than mere 32 that are needed for full utilization of a pair of hyperthreaded 8-core Xeons.

And no, according to Intel's own estimates, even in the best case scenario (SPECInt2006_base) KNL does not quite match performance of dual Xeon E5 2620 v4, which street price is likely 2.5-3 times lower than Growerport.
