How do cores and threads work together?

Can you explain how CPU cores and threads work together?

Sure! CPU cores are the physical processing units, while threads are the virtual components that allow multitasking.

So, does having more threads than cores improve performance?

Yes, it can! More threads allow better utilization of the cores, especially in multi-threaded applications.

What happens if I have more cores than threads?

Having more cores than threads can lead to underutilization of the CPU, but it also means better performance for single-threaded tasks.

Are there any downsides to having too many threads?

Yes, too many threads can lead to context switching overhead, which can actually slow down performance.
