The system cache partition stores temporary system data. It's supposed to allow the system to access appsmore quickly and efficiently, but sometimes things get cluttered and outdated, so a periodic cache clearing can help make the system run more smoothly. It's different from clearing individual app caches, and it won't lead to any loss of personal data or settings. Many authorities suggest a cache wipe after installing a system update.
