The single chip, SiS735, provides a high performance/low cost Desktop solution for the AMD socketA series CPUs based system by integrating a high performance North Bridge, Super-South bridge and an AGP 4X Slot. SiS735 supports 3-DIMM with Double data rate (DDR) SDRAM bandwidth up to 2.1GB/s, or with traditional SDRAM bandwidth up to 1.06 GB/s and also supports an AGP Slot that supports 4X data transfers and Fast Write function.

The "Super-South Bridge" in SiS735 integrates rich peripheral controllers / accelerators / interfaces and is compliant to PC2001. SiS735 provides a total communication solution including 10/100Mb Fast Ethernet for Office requirement and 1Mb/10Mb HomePNA for Home Networking.

SiS735 offers AC'97 compliant interface and also provides interface to Low Pin Count (LPC) operating at 33 MHz clock which is the same as PCI clock on the host, and dual USB host controllers with six USB ports that deliver better connectivity and 2 x 12Mb bandwidth. SiS735 supports up to 6 PCI masters. In addition to the PIC, the super-south bridge also incorporates I/O Advanced Programmable Interrupt controller.

The built-in fast IDE controller supports the ATA PIO/DMA, and the Ultra DMA33/66/100 function that supports the data transfer rate up to 100MB/s. It provides the separate data path for two IDE channels that can eminently improve the performance under the multi-tasking environment.

SiS735 provides one solution to resolve the lack of I/O bandwidth for the previous PC platform with PCI bus bandwidth only up to 133MB/s. SiS735 applies the multi-threaded architecture - "Build-in Multi-threaded I/O Link" to provide enough I/O bandwidth up to 1.2GB/s and increase the hardware parallelism. It will increase efficiently the system total throughput and performance, especially for multi-tasking environment.
