By Auto OC, you mean stock settings and no PBO?
Then the 4.4Ghz probably it's being used only for some spikes and the majority of clocks remain at much lower freqs.

There is a setting that is called AutoOC - which goes up till +200Mhz
It's a maximum boost override, with the downside of two things:
- PBO shifting the voltage curve by "oversuplying" current on "open" limits
- AutoOC messing up the peak targets even more

Both parts need a manual reconfiguration on default PPT, TDC, EDC limits
EDC limit will only be hit on harsh high current loads and is there to limit allcore-provided current
TDC looks to be covering vSOC, and VDDG - it's good to keep it at 98%
PPT is another wording or master target for the TDP
* this "master target" has a place in the boosting curve, and up to your "luck", even if it's not peaking, it could start throttling frequency
** found near 60-70% of it to be a good value, but it's a bit of a stupid topic as it depends on powerdraw ~ which ultimately depends on your EDC limit how much vCore it will push

The normal boosting behavior, nor 1 core full throttle or while gaming - won't ever hit any of the suplied limits
But keep in mind, changing AutoOC scale, will shift the whole boosting table again - soo different PPT, TDC, EDC limits will apply between +100mhz and +200mhz
On the sample i had, i found up till +125Mhz to make sense, but +200 is holded rarely, only on good CCX sillicon
This method is at best compined with CPPC and a powerplan that supports full CCX shutdown - like 1usmus's powerplan
Having a whole CCX sleeping, helps to hold this boost level continously through the test, while TM5 will peak at max boost frequency
~ soo do limit your EDC beyond 100% usage, else degredation happens
