How does the CPU increase the video performance?

The CPU enhances video performance primarily by efficiently managing data processing and executing instructions required for rendering graphics. It handles tasks such as decoding video streams, managing memory access, and coordinating with the GPU for complex graphical computations. By optimizing these processes and minimizing bottlenecks, the CPU ensures smoother playback and better overall video quality. Additionally, advanced CPUs with multiple cores can parallelize tasks, further improving performance in demanding applications.
