50ms seems quite long for embedded applications. OTOH, it has to be long
enough to enter a package idle state and stay there for a while. You
would surely notice it when it kicks in on an Android device.

Do you intend to use it only as a last option? One might want to keep
using inefficient frequencies (P-states) if those don't cause UI lag
