Certainly my Ryzen 3700x has some degree of dynamic voltage scaling. You can see the voltage changing in Ryzen Master. I think intel has it too but not sure. Also, I am not sure it is correct that energy / op is constant, even at a given voltage? I'm no expert but I read about this when I was thinking about overclocking my device. At a given voltage, higher frequencies still use more energy due to the capacitance of all the components on the device. This is why overclocked energy dissipation scales super-linearly with voltage. Because you aren't just increasing the voltage you are increasing the frequency as well.
