between the northbridge and southbridge (ICH called Intel). It is a serial bus to 1 (for the first chipsets) 4-channel bi-directional allowing a channel data rate of 1 GB per second in each direction (full duplex) at a total throughput of 8 Giga byte per second on 4 channels. It is also operates as an interface between the processor I5 and Intel P55 chipset (not all in I7). It replaces the Intel Hub allowing a maximum bandwidth of 266 MB / s.
