Hi, thanks for the issue.
Can you please send the output of running lscpu
in your terminal?
In regards to the memory readings, I don't know what you're comparing Resources with but Resources' readings (of maximally available memory as used memory is not as clear cut) are consistent with GNOME System Monitor's and htop's (depending on data unit prefix), so I'd cautiously assume that the issue may be with the other program's readings.
Ooops, it really reports 6 GHz (bottom list), but in fact
cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq
5137000
cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

I'm pretty sure the frequency scaling is wrong on your CPU because Heterogeneous Core Type support is not merged yet into the mainline Linux kernel. https://www.phoronix.com/news/AMD-Heterogeneous-P-State-Linux https://bugzilla.kernel.org/show_bug.cgi?id=218759
You might be correct, but I guess the lscpu
utility shows a kind of "static data" for the CPU (i.e. theoretical limit), but a real frequency range is controlled by the driver which is an amd_pstate
in passive mode in this case.
What is the max-freq to be displayed as a single value: max{core}{theoretical or real}
or maybe avg{core}{max}{theoretical or real}
there is a question)

I'm sorry but I don't quite understand what you mean by that.
Is there an existing issue for this?
Current Behavior
I also do observe a difference in mem stats. This might not be a problem at all, but please take a look.
