I recently got a Gigabyte Areo 17 i9-12900hk, and have put Ubuntu 22.04 kernel 5.19 on it. I ran s-tui to run it through a quick stress-test and found some odd processor behavior that does not happen in Windows.
Behavior in s-tui: For the first 5-10 seconds, the stress-test runs just fine. Power consumption is in line with power level constraint 1. Constraint 1 is only set to a timer of 3 seconds, but it will run at this power level for about 10 seconds. Then speeds drop and power consumption drops to approx 45w on the core and stays there. Powercap-info shows that constraint 0 (long-term) is set for more than 30 seconds at 70w, so it is clearly ignoring the constraint settings.
According to both s-tui and turbostat, my cpu temps were not too high (maxing at 79c), so I do not think this was thermal throttling. Just to make sure, I removed and purged thermald, but that did not fix the issue.
I have used powercap-set to change both constraint 0 and 1 power levels and timings, but unless I set the power levels to below 45w, the power levels will automatically drop back to 45w after about 10s.
I tried to replicate this behavior in Windows 11, but I can run at high power levels for as long as I'd like without any throttling. HWinfo shows 90w consistently over multiple minutes with no thermal issues during cpu stress tests. Thus, I do not think this is a thermal throttling issue.
Here is the output from powercap-info. One thing I noticed was that the "max_power_uw" in Constraint 0 matches the power consumption levels seen in s-tui after the power consumption levels drop.

Here is the output from turbostat. This shows the initial output and the jump to the stress test. Then the drop after about 15 seconds to 45w.
