You come across the number of CPU cores at the latest when you buy a computer. But what are the benefits of more CPU cores and does it make sense to choose a processor with more cores? Here we explain what the CPU cores are for and whether more CPU cores are always better.
What are the benefits of more CPU cores?
Is a CPU with a higher clock speed or more cores worth it? Not always…
- Processors with multiple cores have been introduced because increasing the computing power by increasing the clock speed brought major technical problems. It is also cheaper to implement several cores in one chip than to have several processors on the board. You will quickly notice that one processor with several cores is usually cheaper than two processors with fewer cores.
- The basic load of the system is distributed across all cores. Your PC or notebook is therefore less likely to be completely overloaded and does not freeze as often. Processors with multiple cores increase the clock frequency and the performance of the PC. In practice, however, the increase in performance depends heavily on the programme being run and the operating system being used. The principle only works if you are working with software that is multi-thread capable, i.e. particularly demanding.
- You should always buy CPUs that have at least 2 cores or more. Whether you buy a CPU with many cores or a high clock speed depends on how you will use it later.
- By the way, you can only compare processors from the same manufacturer and of the same type. An older CPU with eight cores can therefore also be worse than a new CPU with four cores from another manufacturer.
