Intel® 440EX AGPset: 82443EX PCI AGP Controller (PAC)
The Intel® 440EX AGPset, 82443EX PCI AGP Controller (PAC) integrates a Host-to-PCI
bridge, optimized DRAM controller and data path, and an Accelerated Graphics Port (AGP)
interface. AGP is a high performance, component level interconnect, targeted at 3D graphics
applications and based on a set of performance enhancements to PCI. The I/O subsystem
portion of the PAC platform is based on the PIIX4/PIIX4E, a highly integrated version of the
Intelís PCI-to-ISA bridge family. The 82443EX has been developed as the value PC solution to
the standard LX Pentium® II processor platform and is targeted for desktop applications.
