Northbridge vs. Southbridge: What's the Difference?

Edited by Sumera Saeed || By Sawaira Riaz || Published on December 4, 2023
Northbridge connects high-speed hardware like CPU and RAM, while Southbridge manages slower peripherals like USB and hard drives.

Key Differences

Northbridge, a chipset component, plays a crucial role in fast communication between the CPU, RAM, and graphics card. Southbridge, another chipset component, handles slower connections with peripherals like USB ports, hard drives, and expansion slots.
