HyperTransport is a point-to-point, packetized bus. What does this mean?
Point-to-point refers to the topology of HyperTransport technology system interconnect, namely that exactly one source is connected to exactly one destination. Constructing so-called “daisy chains” of HyperTransport devices connects multiple components. Alternative approaches that utilize a shared bus topology are far more difficult to operate at the data rates that HyperTransport technology-enabled devices are designed to achieve. Packetized means that data is transferred across the bus in chunks or packets.
