AMD has enabled the pstate scaling driver for more of their processors in 6.5, so what you are seeing is the new options provided by that driver. There is a new configuration parameter: /sys/devices/system/cpu/cpu0/cpufreq/energy_performance_preference.

@mmstick Thank You. Also, what about display refresh rates? the older kernel can clearly run at 90 and 120 Hz too while the latest kernel only has options for 60 and 165....

Yes, I think this is very much related to #3154...
