Not sure what you mean about stuck at 2 GHz? My current Dell laptop and the previous one used 45 W CPUs and can hold a sustained 3.2 GHz while compiling with 8 threads. That immediately drops as soon as I start using the iGPU or even the Nvidia dGPU, because of power limits and thermal limits. On the desktop, my 5960x from 2014 sustains 3.3 GHz and overclocks to 4.1 all-core, if I want to bother. Ryzen 1700x does 3.7 and the Ryzen 3900 seems to do 4.2 pretty easily. So there's no 2 GHz limit there. Intel is even better, with many desktop chips able to do 5 GHz.
