Multi-Link High-Speed interconnect

HyperTransport (HT) is a state-of-art packet-based, high-bandwidth, scalable, low latency point-to-point interconnect technology that links processors to each other, processors to coprocessors and processors to I/O and peripheral controllers.


HyperTransport is an open standard technology managed, promoted and licensed to the industry at large by the HyperTransport Consortium HyperTransport’s market-proven solidity and highly efficient protocol make it the ideal choice as chip-to-chip, board-to-board and chassis-to-chassis high-performance interconnect, successfully deployed in the widest rage of consumer, commercial and mission-critical applications, including gaming systems, embedded designs, networking equipment, personal computers, workstations, servers, and supercomputers.


HyperTransport Evolution and Milestones Since its inception in 2001, the Consortium has pushed HyperTransport technology toward greater performance, features, architectural flexibility and reliability through new revisions of the HyperTransport link, the HTX slot connector.


AMD's advanced server processors support Hypertransport.


Numascale use Hypertransport since it is the only open psecification that provides interface to an advanced processort to memory interconnection with options for cache coherency.
