TAIPEI, TAIWAN, Nov. 18, 2002 – Silicon Integrated Systems Corp. (SiS), a leading supplier of core logic and graphics chipsets, today launched its second-generation AGP8X core logic chipset, the SiS655. The SiS655 is the first Intel® Pentium® 4 (P4) chipset on the market to have dual channel DDR333, providing double the bandwidth.

"With the SiS655, we've optimized the power of the P4 platform and added SiS technologies and knowhow to create the most powerful, feature-packed and affordable solution available today for the high-end computing market," said Michael Chen, senior vice president, Integrated Product Division, SiS.

The SiS655 supports Pentium® 4 FSB up to 533 MHz, AGP 8X interface, dual channel DDR333 memory controller and the SiS MuTIOL® 1G technology, connecting the SiS655 with the South Bridge SiS963. The SiS655 dual channel DDR333 memory controller fully optimizes the Intel P4-based system performance, doubles the memory bandwidth up to 5.4 GB at advanced 128-bit mode and concurrent 2X64 bit mode, and provides flexible DIMM configuration to enable the dual channel advantage. The SiS655 also supports Hyper Threading™ technology.

The SiS655 is paired with the South Bridge SiS963, which features the IEEE 1394a high-speed connector, USB 2.0 and Dual ATA133/100/66 IDE Channels. Utilizing SiS’ MuTIOL® 1G technology, the SiS655 and SiS963 combination also provides the widest data bandwidth.

The MuTIOL® 1G is an SiS proprietary data bandwidth transfer technology with 1GB/sec transfer speed and bi-directional 16-bit data bus at 533MHz operating speed, allowing a seamless bridge between the SiS655 in the North Bridge and SiS963 in the South Bridge.
