How many cores do you need 2020?

Generally speaking, six cores is usually considered optimal for gaming in 2021. Four cores can still cut it but would hardly be a future-proof solution. Eight or more cores might provide performance improvement, but all this depends mainly on how a particular game is coded and what GPU the CPU would be paired with it.

Where to find the number of CPU cores used by a process?

If you open the performance tab in the Windows task manager, you will see the detailed CPU information of your PC and also the CPU utilization information. Usually, most software are programmed to utilize the CPU cores equally but it’s not always necessary that they share the load equally.

Is there a way to enable all cores in Windows?
