Intel chips, on the other hand, are designed to work with a varying degree of thermal situations because they don't control the laptop it is put in. In this situation, Apple could potentially get more creative with their approach to thermals because they control the entire hardware stack.



Sure, if by "more creative" you mean handicap the CPUs by not delivering them any power because they know they can't cool them.

Intel processors use Intel designed throttling solutions... which exist to keep their own processors from overheating because they have no control over the final implementation.

These new M1 laptops are the first laptops that have complete thermal solutions designed by a single company.

As an example, there is the potential to design a computer with no throttling at all if you are able to control the entire thermal design.

This is not true. A laptop needs to work in a cold room, in a hot room, when its radiator is dusty, etc. If your CPU is not willing to throttle itself then a company with Apple's scale will have machines overheating and dying left and right.

For a computer to never _need_ to throttle, either (1)the cooling system has to be good enough to keep up with the max TDP of the CPU, or (2) you "pre-throttle" your CPU by never delivering it more power than the cooling system could handle. Apple refuses to accept solution 1, so they went with solution 2. If you watch the video I posted, it shows that even when there is adequate cooling, the new macbooks will not deliver more power to the CPU. In effect, the CPU is always throttled below its limit.
