And yup, boost has difference TDP as well, so they can also set it higher for Turbo, and you can check for it by using HWiNFo etc to see how long it can be.
CPU Thermal Design Power (TDP): 35.0 W
CPU IA Cores Thermal Design Current (TDC): 112.0 A
CPU GT Cores Thermal Design Current (TDC): 46.0 A
CPU Power Limits (Max): Power = Unlimited, Time = 64.00 sec
CPU Power Limit 1 (Long Duration): Power = 35.00 W, Time = 32.00 sec [Locked]
CPU Power Limit 2 (Short Duration): Power = 43.75 W, Time = Unlimited [Locked]
This should be set by the BIOS, if I am right, because I saw similar settings on the BIOS hidden settings.
The temp is always the issues here, as if the temp is higher, the current is higher as well.
And you can workaround it by getting a laptop that having dGPU, and not using the iGPU, so you just reduce the current used for CPU, but I don't recommend it as it increase heat and power consumption, unless it(dGPU) has 200% of your iGPU performance.

And ya, I still think that, Windows should still showing the Base frequency as Max frequency, as it is the max frequency it should be.
As you know, there are difference Turbo frequency based on how many Core is parked/unused, so if it is not using max frequency when it is 100% load, the user will be feel strange too.
