Matrox Millennium G400

Windows device driver information for Matrox Millennium G400

The G400 is a video card produced and manufactured by Matrox Semiconductor. It was introduced in September, 1999. The graphics processor has a 2D GUI, video, and Direct3D 6.0 3D accelerator. Toucan was the codename given to it. It was a more powerful and advanced edition of its precursor which is the G200. The Matrox G200 graphics processor had been a triumphant product, contending with the different 2D and 3D combination cards present in 1998. Matrox used the technology developed and polished from the G200 project, improved it, and basically doubled it up to form the G400 processor. The latest chip offered various new and innovative additions, like the multiple monitor output support, an all around 32-bit depicting pipeline with high and quality performance, further improved 2D and video acceleration, and a new 3D feature better known as Environment Mapped Bump Mapping.

The Matrox Millennium G400 is a video card. Internally, it is a 256-bit processor, making use of a 'DualBus' structure. This is an advancement of G200's 'DualBus', which had been 128-bit. A Matrox 'DualBus' chip is composed of twin unidirectional buses which are transporting data into or out of the chip. This improves the effectiveness and bandwidth of data flow within the chip to each of its functional units. G400's 3D engine composed of 2 parallel pixel pipelines with one texture unit each, giving single-pass dual-texturing capability. The Millennium G400 MAX is proficient of 333 megapixels per second fillrate at its 166 MHz core clock speed. It is entirely a Direct3D 6.0 accelerator and, as such, runs short for support for the soon hardware transform and lighting acceleration of Direct3D 7.0 cards. The external memory interface of the chip is 128-bit and is structured to use either SDRAM or SGRAM. It is highly recommended you run a free registry scan for and Matrox Millennium G400 errors before installing any driver updates.
