Hi, Pio.
I'm just a beginner, trying to learn tweaking voltages and TDP limits on my Dell G7, with the same i7 8750H under the hood. I'm using XTU and Passmark CPU MarK (5 iterations, very long test duration) to stress the CPU, and HWMonitor Pro to collect the data.
I've just read all this thread. It's very hard to believe that ASUS has limited the TDP to 25W for this would limit the 8750H to performance worst than a 7th gen. i7U CPU. And that could end on lots of people sueing ASUS for they have not really a 4GHz i7H.
On the other hand, I've seen your data and charts, CPU frequency is really limited. I don't know how this laptop should behave, so I believe yours can be a defective unit or it may have a defective CPU (yes, one in ten thousand, but it happens). Out of the box, one can expect thermal and power throttle, but not a CPU that never reaches the maximum CPU frequency.
Your issue seems to be a frequency limitation. Throttle would reduce from a high frequency for some time, like releasing the foot from the pedal in order to avoid high temp/TDP and them send back again to high frequency (pump the pedal) and so on.
So, excuse me for such naive questions:
1) are you doing the tests with the laptop connected to the power unit?
2) did you check if there's a Windows power profile limiting the CPU frequency? (Settings, Power, Additional power settings, change plan, change advanced, processor power, maximum)
3) do you know somebody else with the same laptop model to compare BIOS versions and tests results?
4) did you contact ASUS support?
5) did you try to return/exchange for a new unit?
6) Since your BIOS version is newer than the last one available at ASUS site, could it be discontinued because of this freq limiting problem?
Just for comparing purposes, I'm happy with G7 performance. I could undervolt and get rid of a little thermal throttle that was lowering the frequency from 3.9GHz to 3.0-3.2GHz when temp overpassed 90oC. Now I'm reducing TDP PL2 limit or even disabling Turbo Boot Short Power Max to reduce or eliminate the power throttling.
If you eventually understand that this is a flaw laptop model and you're able to return it, just do it. New HP Omen seems to be a good value, Dell G7 too.
Good luck,
Mario.
