A more powerful CPU allows for faster and more efficient operation, enabling the computer to handle resource-intensive tasks such as gaming, video editing, and scientific simulations.

3.2 System Performance

The CPU directly affects the overall performance of a computer system. A faster and more efficient CPU can significantly improve system responsiveness, reduce program execution times, and enhance the user experience. It enables smooth multitasking, where multiple applications can run simultaneously without noticeable lag or slowdown.

3.3 Compatibility and Upgradability

CPUs are designed to be compatible with specific computer architectures and socket types. This compatibility ensures that CPUs can be easily upgraded or replaced, allowing users to enhance their system's capabilities over time. Upgrading the CPU can provide performance enhancements without the need for an entirely new computer system.
