VIA, SiS 800MHz FSB product roadmap updates
Charles Chou, Taipei; Christy Lee, DigiTimes.com
VIA Technologies and Silicon Integrated Systems (SiS) recently made slight updates to their new product roadmaps for chipsets supporting 800MHz FSB (front-side bus) speed and the DDR400 memory standard. VIA decided to rename its products the PT series, while SiS now plans to introduce a SiS655FX for dual-channel DDR400 support.
The updates were in response to Intelâ€™s specification changes in its new Springdale platform. The chip giant had announced that instead of 677MHz FSB and dual-channel DDR333 standards, its Springdale products, expected to be launched in the second quarter of 2003, will come with 800MHz FSB and dual-channel DDR400 designs.
Due to the press of time, most chipset designers will introduce products that support single-channel DDR400 first and the dual-channel versions later. However, both versions will support Intelâ€™s Hyper-Threading Technology, which allows one processor to work as a dual-processor set.
As for other new chipset specifications, products with 802.11 WLAN (wireless local area network) support have so far not been seen in companiesâ€™ roadmaps despite designersâ€™ previous announcement that they will start introducing the standard into their desktop-use chipsets. VIA said that it is still difficult to incorporate the MAC (media access controller) into the south bridge chip, as the transmission specification between MAC and RF (radio frequency) has not been standardized yet. However, it will begin the integration process in the second half of 2003, VIA added.
