This describes AMD s Hyper Transport? technology, a new I/O architecture for personal computers, workstations, servers, high-performance networking and communications systems, and embedded applications. This scalable architecture can provide significantly increased bandwidth over existing bus architectures and can simplify in-the-box connectivity by replacing legacy buses and bridges. The programming model used in Hyper Transport technology is compatible with existing models and requires little or no changes to existing operating system and driver software.
It provides a universal connection designed to reduce the number of buses within the system. It is designed to enable the chips inside of PCs and networking and communications devices to communicate with each other up to 48 times faster than with existing technologies. Hyper Transport technology is truly the universal solution for in-the-box connectivity.

Hyper Transport technology provides high speeds while maintaining full software and operating system compatibility with the Peripheral Component Interconnect (PCI) interface that is used in most systems today. In older multi-drop bus architectures like PCI, the addition of hardware devices affects the overall electrical characteristics and bandwidth of the entire bus. Even with PCI-X1.0, the maximum supported clock speed of 133MHz must be reduced when more than one PCI-X device is attached. Hyper Transport technology uses a point-to-point link that is connected between two devices, enabling the overall speed of the link to transfer data much faster
