SUMMARY
intel i3 3110M is the only cpu of my laptop.
As we can read in the following link, it has 2 cores and 4 threads.

https://ark.intel.com/content/www/us/en/ark/products/65700/intel-core-i3-3110m-processor-3m-cache-2-40-ghz.html

However, system monitor sensors wrongly indicate 2 physical CPUs,
1 CPU core and 1 CPU on my system. See the attached screenshot please.

STEPS TO REPRODUCE
1. add System Monitor Sensor widget to desktop
2. open its settings and click on "Sensors details" section
3. search and add these sensors: number of physical CPUs, number of cores
and number of CPUs
4. click on "Ok" button

EXPECTED RESULT
mentioned system monitor sensors should give correct information

Seems to report the exact same details on matter the CPU.

I have the same numbers on my i7-6700.

I have different values after this commit, but they are wrong yet.
Comment 5 Patrick Silva 2021-05-16 17:03:05 UTC
"Number of physical CPUs" sensor no longer exists on Plasma 5.22 beta.
"Number of Cores" and "Number of CPUs" give correct values. :)
