Also it looks like the OP uses amd-pstate and I use acpi-cpufreq since amd-pstate is not enabled by default.

My laptop hits a 4.5GHz frequency wall under Windows 10, Windows 11 and Linux despite power consumption or temperature which are far below this system limits ~51W/100C. I've now tried to open five support requests with HP but they don't even want to confirm the bug. I hoped you would ask me to provide certain CPU registers values to confirm it's a firmware limit. A HWiNFO64 developer refused to confirm the bug citing the global CPU frequency limit confidentiality/NDA: https://www.hwinfo.com/forum/threads/frequency-limit-global-for-ryzen-7-7840hs-zen-4-phoenix-cpu.9044/post-40967 -- You may reply to this email to add a comment.
