MATROX PARHELIA PCI DRIVER

After the launch of Parhelia, Matrox released Parhelia-LX , which supports only bit memory and has only 2 pixel pipelines. The card’s fillrate performance was formidable in games that used many texture layers; though equipped with just 4 pixel pipelines, each had 4 texture units. The Parhelia remained a niche product, and was Matrox’s last major effort to sell into the consumer market. Originally, Matrox planned to produce the “Parhelia 2” successor, codenamed “Pitou”. It remained a niche product, while nVidia and ATI control the majority of the discrete graphics chip market. From Wikipedia, the free encyclopedia. Some writers believed Parhelia to have a “crippled” triangle-setup engine that starved the rest of the chip in typical 3D rendering tasks [1].

The frame buffer is in RGBA Released init was best known for its ability to drive three monitors “Surround Gaming” and its Coral Reef tech demo. For example, in a flight simulator or sim racingthe middle monitor could show the windshield parheliia the left and right monitors could display the side views offering peripheral vision. To further improve analog image quality, 5th order low-pass filters are used.

After the launch of Parhelia, Matrox released Parhelia-LXwhich supports only bit memory and has only 2 pixel pipelines. The Parhelia series was Matrox ‘s attempt to return to the market after a long hiatus, their first significant effort since the G and G lines had become uncompetitive.

The Parhelia processor featured Glyph acceleration, where anti-aliasing of text was accelerated by the hardware. In other projects Wikimedia Commons.

The pco suffix refers to the bit ring bus. Due to their equivalent pricing against faster cards, the Parhelia never got a significant hold in the market.

However, ATI’s Radeon was released later that year, with a considerably larger transistor count million vs. Despite the lackluster performance for its price, Matrox hoped to win over enthusiasts with the Parhelia’s unique and parnelia quality features, such as “Surround Gaming”, glyph acceleration, high resolutions, and 16x fragment anti-aliasing.

This page was last edited on 1 Augustat The “Surround Gaming” support allowed the card to drive three monitors creating a unique level gaming immersion. However, it was all a bit of a moot point because Parhelia’s performance was not adequate to drive most DirectX 9-supporting titles well even without more complex shader code weighing the card down. The card’s fillrate performance was formidable in games that used many texture layers; though equipped with just 4 pixel pipelines, each had 4 texture units.

The Parhelia remained a niche product, and was Matrox’s last major effort to sell into the consumer market.

Dual link TMDS is supported via external controller connected to the digital interface. Retrieved from ” https: Later in Parhelia’s life, when DirectX 9 applications were becoming quite prevalent, Matrox acknowledged that the vertex shaders were not Shader Model 2. Some writers believed Parhelia to have a “crippled” triangle-setup engine that starved the rest of the chip in typical 3D rendering tasks [1].

Presumably there pqrhelia several bugs within the Parhelia core that could not be worked around in the drivers.

This, unfortunately, proved not to be an efficient arrangement in most situations. Views Read Edit View history. As had happened with previous Matrox products, the Parhelia was mstrox just before competing companies released cards that completely outperformed it. The Parhelia was only competitive with the older Radeon and GeForce 3which typically cost half as much.

Unlike previous products, it supports Windows Vista Aero acceleration. However, only 2 displays can be controlled independently. While the Parhelia possessed an impressive raw memory bandwidth much of it was wasted on invisible house-keeping tasks because the card lacked the ability to predict overdraw or compress z-buffer data, among other inefficiencies.

In this case pck was the ATI Radeonreleased only a few months later. However, within a few months after release, the Parhelia was completely overshadowed by ATI ‘s far faster and fully DirectX 9. Originally, Matrox planned to produce the “Parhelia 2” successor, codenamed “Pitou”.
