VIA's P4X600 is equipped with the company's VT8235 south bridge chip, and offers AGP 8x and USB 2.0 support.
Aided by the SiS962 south bridge chip, the SiS655 can support IEEE 1394 in addition to USB 2.0 and AGP 8x. Meanwhile, in common with the company's Rambus DRAM-supporting R658 chipset, the SiS655, supports both single and dual-channel memory modules. Supporting DDR333, the design also allows users to mix dual-channel modules of different capacity.
Intel is also reportedly planning to introduce dual-channel DDR chipsets. Judging from its current roadmap, Intel's first dual-channel product may be the Granite Bay core-based chipsets targeting workstations and servers, but the launch schedule has not yet been settled. In the desktop sector, Intel's dual-channel, Springdale-core chipsets will not be rolled out until the first half of 2003.
