Is HyperTransport technology a parallel bus?
HyperTransport technology is definitely a serial bus, but like all the modern serial busses, it runs on multiple wires. Nobody can say that high speed Ethernet (1Gbit/10 Gbit) are parallel links, however, they do run on multiple wires. HyperTransport is a packet-based protocol. Today’s Ethernet runs mostly TCP-IP a packet based protocol. Many in the communication industry have supported HyperTransport due to its serial nature.
