The SiS 300/SiS 301 is a graphics processing unit that was manufactured by Silicon Integrated Systems.[1][2] This GPU targeted mainstream commercial and consumer markets.


Following the successful SiS 6326 in 1998, SiS introduced the SiS 300 as its replacement. The 3D performance was improved 5 times over the previous GPU, although still considered slow, yet a value solution as a display chip for users that don't use 3D-intensive applications.

The SiS 301 was a companion chip that enabled support for TVs and digital flat panel monitors.


This chip featured a 128-bit memory bus that could access 4/8/16/32/64 MB of RAM, DirectX 6.0 support with multi-textures capability, DVD decoder and an AGP 2x/4x bus to the system.

The SiS 300 was manufactured in a 250 nm process and packaged in a 365 pin PBGA. The SiS 301 was packaged in a 100 pin TQFP.
