MATROX PARHELIA 256 DRIVER DOWNLOAD

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. However, only 2 displays can be controlled independently. By using this site, you agree to the Terms of Use and Privacy Policy. Unlike previous products, it supports Windows Vista Aero acceleration. It remained a niche product, while nVidia and ATI control the majority of the discrete graphics chip market. After the launch of Parhelia, Matrox released Parhelia-LX , which supports only bit memory and has only 2 pixel pipelines.

Matrox Parhelia PCI MB graphics card – MB Overview – CNET

As had happened with previous Matrox products, the Parhelia was released 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.

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

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. To further improve analog image quality, 5th order low-pass filters are used.

Some writers believed Parhelia to have a “crippled” triangle-setup engine that starved the rest of the chip in typical 3D rendering tasks [1]. Later in Parhelia’s life, when DirectX 9 applications were becoming quite prevalent, Matrox acknowledged that the vertex shaders were not Shader Model 2.

Due to their equivalent pricing against faster cards, the Parhelia never got a significant hold in the market. Dual link TMDS is supported via external controller connected to the digital interface.

However, within a few months after release, the Parhelia was completely overshadowed by ATI ‘s far faster and fully DirectX 9. By using this site, you agree to the Terms of Use and Privacy Policy.

Unlike previous products, it supports Windows Vista Aero acceleration. Originally, Matrox planned parhdlia produce the “Parhelia 2” successor, codenamed “Pitou”. Views Read Edit View history. 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.

In this case it was the ATI Radeonreleased only parheliia few months later. This page was last edited on 1 Augustat 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.

Despite the lackluster performance for its price, Matrox hoped to win over enthusiasts with the Parhelia’s unique and high quality features, such as “Surround Gaming”, glyph acceleration, high resolutions, and 16x fragment anti-aliasing. While the Parhelia possessed an impressive raw memory bandwidth much of it paghelia wasted on invisible house-keeping tasks because the card lacked the ability to predict overdraw or compress z-buffer data, among other inefficiencies. This, unfortunately, proved not to be an efficient arrangement in most situations.

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 remained a niche product, and was Matrox’s last major effort to sell into the consumer market. However, ATI’s Radeon was released later that year, with a considerably larger transistor count million vs.

The “” suffix refers to the bit ring bus. However, only 2 displays can be controlled independently. Matrkx “Surround Gaming” support allowed the card to drive three monitors creating a unique level gaming immersion. The Parhelia was the first GPU by Matrox to be equipped with a bit memory bus, giving it an advantage over other cards of the time in the area of memory bandwidth.

Retrieved from ” https: The Parhelia processor featured Glyph acceleration, where anti-aliasing of text was accelerated by the hardware. From Wikipedia, the free encyclopedia. After the launch of Parhelia, Matrox released Parhelia-LXwhich supports only bit memory and has only 2 pixel 2256. For example, in a flight simulator or sim racingthe middle monitor could show the windshield while the left and right monitors could display the side views offering peripheral vision.
