De Peripheral Component Interconnect Special Interest Group (PCI SIG) heeft vrijdag voor Arapahoe gekozen als opvolger van de PCI standaard. Arapahoe is een seriële point-to-point interface die op meer dan 10GHz kan lopen. Het zal nog minstens enkele jaren duren voordat er werkende chips komen die gebruik maken van deze interface, tot die tijd zullen we het moeten doen met PCI of PCI-X. Verrassend genoeg heeft AMD ook gestemd voor Arapahoe als nieuwe standaard, en niet voor haar eigen Hypertransport:
Advanced Micro Devices (AMD), whose HyperTransport interconnect architecture is often viewed as a rival scheme, surprisingly voted in favor of the endorsement, said Gabrielle Satori, head of the recently announced HyperTransport consortium. "We voted yes. HyperTransport is actually complementary to this," Satori said. "There are similarities between the two, but one thing we can't forget is that we have 12.8 Gbytes/second now, and two years from now we'll have much more than that."
HyperTransport, based on a low-voltage differential signaling (LVDS) that can scale up to 32 bits in either direction, will support Arapahoe when the need becomes apparent, Satori said. "We are now building one HyperTransport link to multiple PCI-X links, and if (Arapahoe) is really necessary for users, and the market really needs Arapahoe, we'd just evolve the [HyperTransport] spec and go into it. We are simply doing as we did for all the other I/O technologies."
