hypertransport

HyperTransport is a high-speed, point-to-point interconnect technology developed by HyperTransport Technology Consortium, a group of companies including AMD, Intel, and NVIDIA. It is designed to connect processors, memory, and other components within a computer system, providing a high-bandwidth, low-latency communication link. The technology is based on a packet-switched protocol, which allows for efficient data transfer and error detection.

HyperTransport was first introduced in 2000 as a successor to the older Front Side Bus (FSB) architecture. It was designed to address the limitations of FSB, which could not keep up with the increasing data transfer rates required by modern processors and memory. HyperTransport operates at speeds of up to 32 GT/s (gigatransfers per second), which is significantly faster than the FSB.

The technology uses a differential signaling method, which helps to reduce electromagnetic interference and improve signal integrity. It also supports multiple lanes, allowing for increased bandwidth and scalability. HyperTransport is typically used in server and workstation systems, as well as in some high-end desktop and laptop computers.

In recent years, HyperTransport has been largely replaced by other interconnect technologies, such as PCI Express and QuickPath Interconnect. However, it remains an important technology for certain applications, particularly in the server and workstation markets. The HyperTransport Technology Consortium continues to develop and maintain the technology, ensuring its continued relevance and performance.
