AMD Shanghai won't get HyperTransport 3

HyperTransport 3 which was once slated for AMD's Barcelona server processors seem to be delayed again on Shanghai until some time in 2009 when it finally arrives for the "Montreal" quad- and octal-core CPUs. According to page 21 of Mario Rivas' slides, the roadmap clearly indicates AMD's first 45nm processor Shanghai won't get the newer inter-processor interconnect and it will instead use the older HyperTransport 1 interconnects.

AMD's desktop variant of the Barcelona processor called "Phenom" already has HyperTransport 3 when you use motherboards with AMD's 770 and 790 chipset and the AM2+ socket. But ironically, the multi-socket servers which really need the higher interconnect transport speeds won't get HypertTranport 3 for another two generations of server processors.
