Do you understand "When one core in trouble, others do nothing"?XD

"Abstract:" Have you heard about the king, the legend, the lead runner, it's the eight cores phone.

What can impact the performance of the phone?

1. performance of a single-core, e.g.: the better performance is all of a72 than all of a53(based on all the cores are working).
2. Scheduling, you need to find a balance between performance and power consumption. So sometimes, the scheduling algorithm of the phone will work for the balance.
3. Not common the multiple cores situation.

Next, I want to introduce cores and logical processors on PC.

As you can see, my computer is two cores and four logical processors. What's that?

A processor may comprise of many cores, so basically, the processor is a set of cores or even a single core. The physical core is the thing that actually exists, it has an ALU, CU, GPRs, etc and has threads for process execution but if a processor has more than a single thread (called as Hyper-threading) then even more processes can be executed simultaneously and the OS sees or identifies that particular thread as a distinct core called as Logical Core.
