Parhelia biography, Parhelia discography
It was best known for its ability to drive three monitors ("Surround Gaming") and its Coral Reef tech demo.Background
The Parhelia was Matrox's attempt to return to the market after a long hiatus, their first significant effort since the G200 and G400 lines had become uncompetitive."G400" technology and were not competitive with ATI's Radeon or NVIDIA's GeForce lines with regards to 3D computer graphics.The "Surround Gaming" support allowed the card to drive three monitors creating a unique level gaming immersion.RAMDACs with full gamma correction.The Parhelia could drive a 30" Apple Cinema Display at its native resolution of 2,560 x 1,600.The card was released in two memory configurations, 128 MB or 256 MB or DDR RAM.USD), the Matrox Parhelia's 3D gaming performance was well behind NVIDIA's older and similarly priced GeForce 4 Ti 4600.The Parhelia was only competitive with the older Radeon 8500 and GeForce 3, which typically cost half as much.The Parhelia's potent performance was held back by its comparatively low GPU clock speed, which in turn was initially believed to be limited by its large number of transistors.The card's fillrate performance was only formidable if a game used many layers of textures because it was only equipped with 4 pixel pipelines, but each had 4 texture units.Unfortunately this did not turn out to be an optimal approach for games.Parhelia was also hampered by limited bandwidth saving technologies, while ATI had their 3rd generation HyperZ in Radeon 9700 and NVIDIA had their Lightning Memory Architecture 2 in GeForce 4.Later in Parhelia's life, when DirectX 9 applications were becoming quite prevalent, Matrox acknowledged that the vertex shaders were not Shader Model 2.Presumably there were several bugs within the Parhelia core that could not be worked around in the drivers.However, within a few months after release, the Parhelia was completely overshadowed by ATI's far faster and fully DirectX 9.Due to their equivalent pricing against faster cards, the Parhelia never got a significant hold in the market.It remains a niche product today while nVidia and ATI control the majority of the discrete graphics chip market.Future products
Originally, Matrox planned to produce the 'Parhelia 2' successor, codenamed 'Pitou'.Parhelia processors were later upgraded to support AGP 8x, and PCI Express.This page was last modified on 20 June 2008, at 22:17.The Matrox Parhelia, a series of computer graphics processors.This disambiguation page lists articles associated with the same title.If an internal link led you here, you may wish to change the link to point directly to the intended article.This page was last modified on 4 June 2008, at 17:48.All text is available under the terms of the GNU Free Documentation License.Designed for the demanding needs of medical imaging, air traffic control professionals and embedded solutions professionals.They are most easily seen
