How does a “core” and “thread” in a processor work? What is their difference?
In: 125
CPU cores and threads are two different types of processors.
Cores are physical processing units that can run one task at a time, while threads are virtual sequences of instructions given to a CPU.
Cores increase the amount of work that can be accomplished in a time, while threads help organize and optimize that workload.
Multithreading allows for better utilization of available system resources by dividing tasks into separate threads and running them in parallel. Hyperthreading further increases performance by allowing processors to execute two threads concurrently.
When multiple cores are present on the same chip, communication time with cache and RAM is less, data access is faster, and the printed circuit board needs less space when a multicore processor is used.
