Modern processors are capable of multitasking, the presence of multiple cores in this sense is a determining factor. Temperature sensors sometimes display data on the monitor in which core temperatures can vary widely, which is confusing for ordinary users.
It is worth worrying only when the processor temperature reaches critical values and there is a possibility of overheating. In other cases, the difference in core temperatures is normal and should not cause concern.
Each of the cores has several processes that they serve. In case of idle or inactive use of the operating system functions, the processor issues a command to service them to one or more cores, which, when measured, will show a higher temperature than all the others.
In the case of multitasking and a large number of cores, which AMD processors are famous for, one or more cores are always in the mode of distributing tasks between the rest of the cores, it is these, distributing roles, the brain centers of the processor that will be significantly hotter.
During games and other energy-consuming processes, each of the cores will heat up accordingly with the frequency of its involvement in solving a common problem. In this case, the cores responsible for the graphics component will get hotter than the others.
Uneven cooling of the processor surface is a common cause of varying core heating. In most of these cases, thermal paste is to blame, either dry in a certain area, or incorrectly distributed over the processor initially.
