Taipei, March 10, 2005 --- Silicon Integrated Systems today announced the release of three new chipset products for notebook computers powered by AMD (NYSE: AMD). The SiSM760, SiSM761GX and SiSM770 chipsets support the latest AMD Turion™ 64 mobile technology and are fully compatible with the latest power-saving technology for improved reliability and performance for notebook computers. Additionally, the SiS chipsets also support the advanced PCI Express specification, bringing the advantages of PCIe into the realm of mobile computing. When combined with SiS wireless LAN chips, SiS fully satisfies the mobile computing needs of today and tomorrow for AMD Turion 64 mobile technology.
 
The new AMD Turion 64 mobile technology is based on the AMD64 architecture, bringing advanced 32- and 64-bit technology to the high-end market for thinner and lighter notebooks. This technology enables longer battery operation, while the SiS chipsets contribute to the "thin and light" design of the AMD Turion 64 mobile technology-based notebooks. All three new SiS chipsets support AMD's advanced 1600MT/s HyperTransport™ technology for improved system performance and low-latency, high-efficiency data transfer. The SiSM761GX chipset also features SiS's exclusive HyperStreaming™ technology, which provides intelligent data flow management for maximum performance in parallel resource allocation and concurrent / batch processing of data flow packets. HyperStreaming™ technology delivers revolutionary performance for high-end mobile computing platforms. The SiSM760 chipset has now entered mass production, marking one of the first AMD Turion™  64 mobile technology-based chipset products to enter the market.
 
"SiS has aggressively developed a series of excellent chipset products, providing customers another choice for AMD64 mobility," said Chris Cloran, director, mobile marketing, Microprocessor Business Unit, CPG, AMD. "AMD Turion 64 mobile technology is designed to be the most advanced family of simultaneous 32- and 64-bit Windows®-compatible processors available for thin and light notebook PCs."
 
"The SiSM760, SiSM761GX and SiSM770 chipsets for AMD Turion 64 mobile technology are the most ground-breaking products developed by SiS to date," said Daniel Chen, the CEO and President of SiS, "With our wealth of R&D experience and exclusive technologies, SiS is leading the market by providing a most efficient, most reliable and most consumer-minded group of products for AMD Turion  64 mobile technology."
 
By adopting SiS' revolutionary Mirage™ graphics core, the chipsets provides among the best graphics performance for all the users of the AMD64 platform. The SiSM761GX and SiSM770 also support the new PCI Express X16 interface, which provides an 8GB/s bi-direction transfer rate, compared with the current AGP 8X standard of 2.1GB/s. Combined with SiS' latest South Bridge Chipset SiS966 / SiS966L, SiS offers buyers a formidable combination that is ready for the next generation of peripheral devices thanks to PCI-E support. The SiS966 / SiS966L support 2 PCI-E x1, Gigabit Ethernet, 8 USB 2.0 ports, High definition 7.1 channel sound, 4 SATA and 4 PATA. The SiS966 / SiS966L also support Multiple RAID disk array modes in RAID0, 1, 0+1 and JBOD.
