GMA X3500 is an upgrade of the GMA X3000 and used in the desktop G35. The shaders support shader model 4.0 features. Architecturally, the GMA X3500 is very similar to the GMA X3000, with both GMAs running at 667 MHz. The major difference between them is that the GMA X3500 supports Shader Model 4.0 and DirectX 10, whereas the earlier X3000 supports Shader Model 3.0 and DirectX 9. The X3500 also adds hardware-assistance for playback of VC-1 video.
