HT 3.1 Specifications
HT 3.1 was released on August 18, 2008. It delivers 23% of bandwidth improvement and proportionally lower latency capability compared to the HT 3.0 release. HT 3.1 maintains the same advanced architectural, power management and protocol features of HT 3.0, plus:
2.8 GHz, 3.0GHz and 3.2 GHz Clock Rates
51.2 GB/s Max Aggregate Bandwidth (32-bit)
25.6 GB/s (204.8 Gb/s) Max Bandwidth per
Unidirectional HT Link (32-bit)
6.4 GT/s (3.2 GHz x 2 DDR) per Lane
With the extended clock rate and bandwidth capabilities of the HT 3.1 specifications, the Consortium reinforces its mission of keeping HyperTransport specifications comfortably ahead of industry requirements, thus safeguarding long term investments in the technology.
