Desktop cpu in a laptop vs Mobile cpu bottleneck?

[Shadowman]

First of all just want to be clear this is purely based on performance not how thick the laptop will be or it will take 2 power adapters etc... just pure performance.
I just kind of wanted a idea in regards to gaming laptops, I see all these gpu’s like Rtx 2070, Super 2080 etc... but are they being bottlenecked by the cpu (mobile) and if the cpu was a proper desktop version (in a laptop) would it perform better? Like  for example following 2 laptops 

 

RTX 2070 Super (not max-q) with a i7 10750h (mobile)

vs a

RTX 2070 Super (not max-a) with a i7 10700k  (desktop)

 

How better would the desktop version laptop perform in regards to FPS in games? I mean is the difference huge or just a little?

Cooling and power unlimited, the CPU performance difference is around 40% (since that's the all core turbo limit and core count difference). It does not mean a laptop with desktop CPU is automatically superior to one with mobile version in reality because you have to pop this
