Mirage 3 IGP has been widely adopted in SiS IGP chipsets including 671/671FX for Intel platform and 771 for AMD platform. Compared with Mirage 2 IGP, the 3D capability has been greatly upgraded. The changes include upgrades of Direct X 8 to 9, Pixel Shader 1.3 to 2.0, OpenGL 1.4 to 1.5, 4 Texture Units to 16 Texture Units, 200MHz core to 250MHz. and 128MB shared memory to 256MB.
