Explanation

The backside bus (BSB) is a dedicated high-speed bus that connects the CPU directly to its L2 (Level 2) cache. Because it is a private, dedicated connection, the backside bus operates at or near the processor's own clock speed, providing very fast cache access without competing with other system traffic. In contrast, the frontside bus (FSB) connects the CPU to the system memory controller and the rest of the motherboard. PCI is an expansion bus for peripheral cards, and the system I/O bus handles communication between the CPU and I/O devices - neither connects the L2 cache to the processor.
