Do CPUs or GPUs provide fine grained energy consumption data?

I want to determine the amount of Watt-seconds my computer uses, as accurately as possible. Do desktop, laptop or smartphone computers monitor this and provide any means to access this information?

So far I'm only aware of battery monitoring on mobile devices, e.g.

$ upower -i $(upower -e | grep BAT)
  native-path:          BAT0
  power supply:         yes
  has history:          yes

    rechargeable:        yes

    1562942608  36,000  discharging
  History (rate):

on Linux.
