Chapter 2 System Overview
2.4 SYSTEM ARCHITECTURE
The Compaq D315 and HP d325 feature an architecture based on the AMD Athlon XP processor
and an NVidia NForce chipset (Figure 2-6).
The AMD Athlon XP processor features an x86-class CPU that uses a highly-pipelined
architecture to process a high volume of data per clock cycle to provide exceptional performance
in handling audio, video, and image files. Operating at speeds up to 2.13 GHz, the Athlon XP
processor is optimized for the Microsoft Windows XP operating system.
The D315 model uses a Nvidia NForce 220 chipset while the d325 model uses the NForce2 420
chipset. Both chipsets include the following functions and features:
♦ Athon XP processor support
♦ Integrated Graphics Processor (IGP) providing:
• Integrated GeForce MX-class graphics controller
• AGP interface support for graphics upgrade
• SDRAM controller supporting two DDR DIMMs
♦ Media & Communication Processor (MCP) providing:
• Two IDE controllers supporting up to four ATA100 storage devices
• Six USB ports
• AC link interface servicing the audio controller
• PCI bus controller supporting up to three 32-bit 33-MHz PCI expansion devices
• LPC bus interface serving the BIOS ROM and super I/O component
