> I don't see this regression on BXT devices

I mean, it's not consistently visible on all BXT devices, and drop is much
smaller than variation in Triangle test on these TDP limited devices i.e. the
drop is visible only when looking at variance range change in a trend, you
won't get conclusive results with normal perf comparison.

Also, when looking at perf trend, there's a drop visible in one J4205 device,
but not in the other one (they have small perf diff in general, although they
should be identical). Perf has likely dropped a bit on A3960 & J3455 too, but
there it's even smaller.

-> best comparison HW is SKL.
