AMD introduces the AMD-8111™ HyperTransport™ I/O
hub. This feature-rich core-logic component provides sophisticated I/O
functionality to systems implementing HyperTransport technology. Replacing
the traditional "Southbridge," this component integrates storage, connectivity,
audio, I/O expansion, security, and system management functions into a
single device.
