SiS wasn't far behind Intel with its own dual-channel chipset – the 655. This goes one step further than the e7205 to offer PC2700 support for a bandwidth of 5.4GB/s, far in excess of the 533MHz FSB Pentium 4's capability, giving extra room for AGP and I/O. AGP 8x support is also part of the specification. A proprietary interconnect, which the company calls MuTIOL 1G, provides a bandwidth of 1GB/s between the Northbridge and 963 Southbridge. The latter features integrated controllers for six-channel audio, USB 2.0 and FireWire, bolstering the chipset’s appeal.
Performance is good compared to the 845 and e7205, mainly due to the additional bandwidth and 1GB/s MuTIOL 1G link.
