New spec extends HyperTransport to 3.2GHz

Increase together with HyperTransport's double datarate capability yields aggregate performance of 51.6Gbyte/s.

Further extending the capabilities of the industry's highest performance, lowest latency interconnect technology, the HyperTransport Technology Consortium (HTC) has released the HyperTransport 3.1 specification.

The new specification extends the 2.6GHz maximum clock speed of HyperTransport 3.0 to 3.2GHz.

This increase together with HyperTransport's double datarate (DDR) capability delivers up to 6.4Gtransfer/s per bit and yields aggregate performance of 51.6Gbyte/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, 3.0 and 3.2GHz.

This increase in clock speed delivers a 23% 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 3.2GHz 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.

The new HyperTransport 3.1 specification is openly available today and can be downloaded directly from the HyperTransport Technology Consortium's website.
