Dissipation is the result of an irreversible process that takes place in inhomogeneous thermodynamic systems. A dissipative process is a process in which energy (internal, bulk flow kinetic, or system potential) is transformed from some initial form to some final form; the capacity of the final form to do mechanical work is less than that of the initial form. For example, heat transfer is dissipative because it is a transfer of internal energy from a hotter body to a colder one. Following the second law of thermodynamics, the entropy varies with temperature (reduces the capacity of the combination of the two bodies to do mechanical work), but never decreases in an isolated system.
These processes produce entropy (see entropy production) at a certain rate. The entropy production rate times ambient temperature gives the dissipated power. Important examples of irreversible processes are: heat flow through a thermal resistance, fluid flow through a flow resistance, diffusion (mixing), chemical reactions, and electrical current flow through an electrical resistance (Joule heating).
Designing CPUs that perform tasks efficiently without overheating is a major consideration of nearly all CPU manufacturers to date. Some CPU implementations use very little power; for example, the CPUs in mobile phones often use just a few hundred milliwatts of electricity, while some microcontrollers used in embedded systems may consume only a few milliwatts or even as little as a few microwatts. In comparison, CPUs in general-purpose personal computers, such as desktops and laptops, dissipate significantly more power because of their higher complexity and speed. These microelectronic CPUs may consume power in the order of a few watts to hundreds of watts. Historically, early CPUs implemented with vacuum tubes consumed power on the order of many kilowatts.
This is a list of CPU power dissipation figures of various consumer central processing units (CPUs).
Early CPUs
Note that these figures include power dissipation due to energy lost by the computer's power supply and some minor peripherals. However, since the CPU component of these early computers easily accounted for most of the computer's power dissipation, they are mentioned here:
If not stated otherwise, the watts dissipated refers to the peak-value thermal design power for a whole processor family. Since thermal design power relates to the potential maximum thermally significant power used by the most energy using member of a processor family, it is not useful for comparing processors within a particular family. It is also not useful for comparison of the energy efficiency of individual processors in different families, because it relates to the family, not the individual CPU. Thermal design power is defined differently by different manufacturers, so it is not comparable between manufacturers.
This video explain the CPU power dissipation formula and talks about the evolution over the years of power dissipation, clock rate and miniaturization.

Why Are Laptop Manufacturers Keeping Us In The Dark About CPU Power?
As a consumer I want to know what I am getting for my money. So why do laptop manufacturers not tell us what the CPU power is?
I tested a Lenovo IdeaPad Pro 5i 16" and a Lenovo Yoga Pro 9i 16", both with an Intel Core Ultra 9 185H CPU. One has a PL1 of 65W and one has a PL1 of 80W. What effect does this have across several tests?

Dissipation is the result of an irreversible process that takes place in inhomogeneous thermodynamic systems. A dissipative process is a process in which energy (internal, bulk flow kinetic, or system potential) is transformed from some initial form to some final form; the capacity of the final form to do mechanical work is less than that of the initial form. For example, heat transfer is dissipative because it is a transfer of internal energy from a hotter body to a colder one. Following the second law of thermodynamics, the entropy varies with temperature (reduces the capacity of the combination of the two bodies to do mechanical work), but never decreases in an isolated system.
These processes produce entropy (see entropy production) at a certain rate. The entropy production rate times ambient temperature gives the dissipated power. Important examples of irreversible processes are: heat flow through a thermal resistance, fluid flow through a flow resistance, diffusion (mixing), chemical reactions, and electrical current flow through an electrical resistance (Joule heating).
