Intel Stakes Its Vision of the PC Future with 775 Launch

915G Express Chipset, Continued

As for the architecture of the GMA 900, there's very little that can be said about it at the moment, since Intel is keeping mum on the details. What we do know, though, is that the chip has four pixel pipelines with Pixel Shader 2.0 support with 16 or 32 bit floating point precision, it has no Vertex Shader units and can perform T&L only through software. FSAA and anisotropic filtering are not supported! Intel does not talk about transistor count numbers.
