Why not?  Power savings features have worked very smoothly for quite
some time.  Back-in-the-day there were many problems.

Newer systems also scale their clock-rate and other featuers on a
moment-by-moment basis,  which means power consumption floats *allot*
(highly variable) but over any reasonable stretch of time modern systems
come out ahead.
