The HyperTransport consortium just announced new 3.0 specifications. If the first version was restricted to 800 MHz and the second to 1.4 GHz, the third is this time at no less than 2.6 GHz. The bandwidth increases from 22.4 GB /s for the V2 to 41.6 GB /s for the v3 (or 20.8 GB /s for both directions. The v 3.0 also includes hot plugging and dynamic power management. It also gives the possibility optionally to extends HyperTransport’s maximum signal transmission distance to 1 meter with no performance degradation and configure 1x16 HyperTransport links as 2x8 virtual links. FYI, Athlon 64 processors communicate with their chipsets via 800 MHz HyperTransport bus in Socket 754 and 1000 MHz in Socket 939.
After Centrino and Viiv, Intel releases VPro. Intel speaks of a technology but it would be more accurate to say that it is a marketing denomination that gathers several technologies that will be included in upcoming products.
Intended to professionals, “VPro” PCs to be released during the second half of the year will be based on a processor using Intel’s Core architecture and Virtualization Technology. They will have to be coupled to a i965G in order to support the second version of the Active Management Technology and the latest integrated graphic chip.
