Anyone running amd_pstate=active? I have read the cpu governor has changed as well if this mode is in use.

New thread, new luck .
On linux63 I tested amd_pstate=active .
It told me that turbo-boost is not available, but cpu frequency went down to 400.
Ryzen 6850u, igpu.
But I get the same result with passive mode when unplugged (but still have turbo-boost, when plugged to the wall), but there is probably more, it was a short try.
I know that there is the new driver in use amd_pstate_epp
That’s the only difference that I know by now. Will test later.
see this for amd p-state epp driver ( kernel 6.3 or more )

What confuses me a bit,
the amd_pstate=passive mode shows 4 pstates
the amd_pstate=active mode shows 3 pstates.
And the 4 pstates are Documented the 3 not.
https://docs.kernel.org/admin-guide/pm/amd-pstate.html#cpupower-tool-support-for-amd-pstate
but it seams to be faster.
Will switch to 6.3 later on when 6.2 gets EOL.
Maybe AMD CPPC Performance Capability is not working correctly?
Since 6.3.3 is in stable I use amd_pstate=active anyone else noticed on Desktop Systems CPU governor is set to performance as I read balanced_performance should be default.

Yes, I found this: AMD P-State EPP Scaling Driver on AMD Ryzen 7 5800H laptop
Basically performance is active and it actually leads to excessive power draw because presumable integrated GPU gets 1.46V all the times.
I encourage you to check your voltages and power draw.
I use amd_pastate=active which means using the amd-pstate-epp.
