HyperTransport Consortium Boosts Clock Speeds to 3.2 GHz

Further extending the capabilities of the industry's highest performance, lowest latency interconnect technology, the HyperTransport(TM) Technology Consortium (HTC) today released the HyperTransport 3.1 specification. The new specification extends the 2.6 GHz maximum clock speed of HyperTransport 3.0 to 3.2 GHz. This increase together with HyperTransport's double data rate (DDR) capability delivers up to 6.4 GigaTransfers/second (GT/s) per bit and yields aggregate performance of 51.6 gigabytes per second (GB/s).

"The HyperTransport interconnect continues to extend the industry-leading performance that compute-intensive system designs expect," said Mario Cavalli, general manager of the HyperTransport Technology Consortium. "For nearly a decade, our technology has proven to be the industry's most powerful, most widely adopted and future-ready interconnect standard, and is the highest performance interconnect technology specified in products shipping today. In addition, as a mature, robust solution, HyperTransport has proven to be the interconnect of choice for mission-critical applications and benefits from the strength of a large and fast-growing product ecosystem."

HyperTransport is a high-bandwidth, point-to-point interconnect standard that provides the lowest latency for chip-to-chip, board-to-board and chassis-to-chassis links. The HyperTransport 3.1 specification defines three new clock rate steps of 2.8 GHz, 3.0 GHz and 3.2 GHz. This increase in clock speed delivers a 23 percent increase in aggregate bandwidth.

"It is significant that the HyperTransport Consortium has proven its ability to further consolidate interconnect performance leadership with the release of the HyperTransport 3.1 specification," said Jag Bolaria, senior analyst, The Linley Group. "The standard has empowered millions of high-performance products on the market today, proving the stability and robustness of the technology. The move to 3.2 GHz is the next natural progression."

HyperTransport technology has continued to enjoy significant market momentum and adoption, with nearly 63 million HyperTransport technology-based products expected to ship in 2008. In addition to HyperTransport 3.0, HyperTransport 1.0 and 2.0 continue to be designed into end systems at an accelerating rate. Analysts estimate that the interconnect technology is used in nearly one quarter of all servers and edge routers, and one-third of the world's Top500 supercomputers. HyperTransport is also at the core of storage area networks (SANs) and core router products.

About the HyperTransport(TM) Technology Consortium

The HyperTransport Technology Consortium is a membership-based, non-profit organization that licenses, manages and promotes HyperTransport Technology. The HyperTransport Consortium was founded in 2001 by leading technology innovators like AMD, Apple, Broadcom, Cisco, NVIDIA, PMC-Sierra and Sun Microsystems and counts more than 60 industry-leading members worldwide, including industry leaders AMD, Broadcom, Cisco, Dell, HP, IBM, NVIDIA, Renesas and Sun Microsystems. Consortium membership is based on a yearly fee and it is open to companies interested in licensing the royalty-free use of HyperTransport technology and intellectual property. Consortium members have full access to the HyperTransport technical documents database, they may attend Consortium meetings and events and may benefit from a variety of technical and business promotion services that HTC offers at no cost to its members.
