System Overview

2.3System Architecture

The systems covered in this guide feature an architecture based on an AMD processor and chipset (Figure 2-2). All systems covered in this guide include the following key components:

■AMD Phenom, Athlon, or Sempron processor.

■AMD 780V chipset (includes RS780 north bridge and SB700 south bridge)

■SCH5327 Super I/O (SIO) controller supporting PS/2 keyboard and mouse peripherals

■AD1884A audio controller supporting line in, line out, microphone in, and headphones out

■Broadcom BMC5754 GbE network interface controller

The AMD 780V chipset, consisting of the RS780C north bridge and the SB700 south bridge, is designed to complement the latest AMD processors. The RS780 north bridge communicates with the processor through a Hypertransport bus and with the SB700 south bridge component. The integrated graphics controller of the RS780 north bridge can be upgraded through a PCI Express (PCIe) x16 graphics slot. All systems include a serial ATA (SATA) hard drive in the standard configuration.
