Why? And why would you limit it to laptops? Literally all CPUs and GPUs whether they are laptop or high end desktop PCs have this problem. It's why the watercooling crowd get a nice performance boost in benchmarks even without changing any settings on their PC. The thermal envelope is just a design feature in modern PC components. You want to know actual performance, go look up benchmarks for your particular device. If you're not happy with something return it. There's no reason to throw yet more meaningless confusing data at consumers who largely already don't know what they are looking at.
Desktops for gamers etc are usually correctly specced, even if not, then adding a $100 3 fan radiator and cooling is easy. With a laptop this is almost impossible without creating somethign that is no longer a laptop. My desktop can fuilly utilise the GPU without the fans ever needing to go much beyond 50% regardless of how long I use it. many of these gaming laptops the GPU is limited within a few mins of heavy usage unless you have it sitting on some huge laptop cooler thus defeating the purpose of it being a laptop.
The sum of the Universe is zero.
