SiS662 chipset has taken the place of SiS661, which is SiS last-generation chipset for Intel P4 platform, to become the most cost-effective product for entry-level motherboard market. The most competitive ability of SiS662, particularly designed for Intel Pentium D and Intel Pentium 4 FSB 800 processor, is its specification of fully supporting new-generation technology such as dual core processor, 64-bit operating system, DDR2-667 memory, PCI Express interface, and more.
Integrated with advanced Mirage graphics engine, SiS662 chipset enables the performance of 3D and DVD playback thoroughly. Also, it supports one PCI Express x 16 interface to provide single transmission bandwidth up to 4GB/s, which is faster than transmission speed of 2.1GB/s that AGP 8X can provide. Furthermore, SiS662 chipset can be combined with SiS307 video chip to have perfectly high-definition image of DVD and HDTV.
SiS provides motherboard makers flexibility of choosing SiS966 or SiS966L Southbridge to be combined with SiS662 Northbridge chip. SiS966 supports 2 PCI Express x 1 ports, 8 USB2.0 controllers, 4 Serial ATA ports and 4 parallel ATA ports; SiS996L supports 2 PCI Express x 1 ports, 8 USB2.0 controllers, 2 Serial ATA ports and 4 parallel ATA ports.
