Will Meteor Lake stop the age-old performance throttling on laptops? (alien.top)

Over the past 15 years I have bought cheap (Dell Inspiron) and expensive (Lenovo Business) laptops and no matter what: (a) the battery life always sucked, and (b) I never knew until a few years ago that CPU performance is always throttled no matter how powerful the CPU is that you purchased. The latter point made me not only mad, but upset because I wasted so much money on my last high-spec Lenovo laptop.

So my question is will these Meteor Lake chips really stop the performance throttling, stop the fan being on constantly, and of course, will the battery life really improve? I'm so sceptical based on my experience with x86 laptops. (FYI - I purchased an M1 MacBook Pro after it launched, and it has been the laptop I always needed. At home, I have an AMD-Ryzen 3600 tower PC that I built myself, which I'm happy with).

No.

CPU performance is always limited by some reason. In laptops it will almost always be heat, which is the same as power consumption. There is no reason not to drive the CPU as hard as it can on a given cooling and battery solution. You bought a high spec lenovo laptop which is probably configured to run as fast as possible. Did you even try to setup it otherwise?

Typical idle use (like typing reddit) power for my old lenovo intel laptop is about 5W which results in about 8 hour battery life with this small old battery. I don't think I ever hear the fans of the laptop unless I am running a compiler or something. I could setup it so that I would not hear the fans even then but that would cost some performance.
