* Bus - Shared topology
* * AMD uses HyperTransport 2.0 on all CPUs based on sockets 939 and AM2, however, supporting only the lower HT2 speed. In fact, AMD was more interested in the PCI Express mapping feature than a higher transfer speed. So even though these processors are based on HT2, the maximum transfer rate of their HT links is 4,000 MB/s.
