Diamond Speedstar A70

This SiS 6326-based card doesn't really earn the name 'Speedstar'. It's rather slow and not suitable for 3D-gaming. It lacked OpenGL upon release and basic OpenGL support was implemented after 2 years of driver development. Despite low performance it's 2D performance was acceptable and the chip was very cheap to manufacture. The SiS chip can be found on budget boards and as on-board solution on motherboards.

According to Wikipedia SiS shipped over 7 million in 1998. A decent quantity!
