The SiSM672MX, supporting Pentium® M series processor, features a PCI Express x16 Bridge, flexible Single-Channel DDR2-667 Memory controller, Mirage™3+ graphics engine, and SiS MuTIOL® Technology, which connects with the SiS968 MuTIOL® Media I/O.

The advanced Mirage™3⁺ graphics engine, combining with Pixel Shader 2.0, Texture Pipelines, Texture Filtering and Cubic Mapping technologies, enables the SiSM672MX integrated chipsets for desktop PCs to deliver excellent graphics performances under 2D and 3D conditions. With support of SiS Real Video Technology, the image quality and definition of digital entertainment devices, such as TV, VCD, and DVD can be presented perfectly and thoroughly under Windows Vista™ Premium Edition.

The PCI Express is a new standard of I/O interconnect. It has several advantages over legacy PCI. Furthermore, it is PCI compatible in software. The SiSM672MX integrates a x16 Host-to-PCI Express bridge that is compliant with PCI Express SPEC 1.1. It also has lane reversal capability to provide maximum flexibility.

SiS MuTIOL® technology is developed into three layers: the Multi-Threaded I/O Link Layer delivering 1.2GB/s bandwidth to connect embedded DMA Master devices and external PCI masters to interface with the Multi-Threaded I/O Link Layer, the Multi-Threaded I/O Link Encoder / Decoder in SiS968 to transfer data at 1GB/s bandwidth from / to the Multi-Threaded I/O Link Layer to / from the SiSM672MX, and the Multi-Threaded I/O Link Encoder / Decoder in the SiSM672MX to transfer data at 1GB/s from / to memory sub-system to / from the Multi-Threaded I/O Link Encoder / Decoder in SiS968.
