MATROX PARHELIA 256 DRIVER DOWNLOAD

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. Some writers believed Parhelia to have a “crippled” triangle-setup engine that starved the rest of the chip in typical 3D rendering tasks [1].

As had happened with previous Matrox products, the Parhelia was released just before competing companies released cards that completely outperformed it. 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. Originally, Matrox planned to produce the “Parhelia 2” successor, codenamed “Pitou”.

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

Unlike previous products, it supports Windows Vista Aero acceleration. To further improve analog image quality, 5th order low-pass filters are used.

The Parhelia was only competitive with the older Radeon and GeForce 3which typically cost half as much. In JuneMatrox announced the release of M-Series video cards. The “Surround 2256 support allowed the card to drive three monitors creating a unique level gaming immersion.

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 natrox offering peripheral vision. After the launch of Parhelia, Matrox released Parhelia-LXwhich supports only bit memory and has only 2 pixel pipelines.

The “” suffix refers to the bit ring bus. As had happened with previous Matrox products, the Parhelia was released just before competing companies released cards that completely outperformed it.

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

Retrieved from ” https: 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. Presumably there were several bugs within the Parhelia core that could not be worked around in the drivers. Some writers believed Parhelia to have marrox “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. Dual link TMDS is supported via external controller connected to the digital interface. Despite the lackluster parheli 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.

However, only 2 displays can be controlled independently. Released init was best known for its ability to drive three monitors “Surround Gaming” and its Coral Reef tech demo.

Due to their equivalent pricing mwtrox faster cards, the Parhelia never got a significant hold in the market. From Wikipedia, the free encyclopedia.

The Parhelia processor featured Glyph acceleration, where anti-aliasing of text was accelerated by the hardware. The frame buffer is in RGBA However, within a few months after release, the Parhelia was completely overshadowed by ATI ‘s far faster and fully DirectX 9.

This, unfortunately, proved not to be an efficient arrangement in most situations. However, ATI’s Radeon was released later that year, with a considerably larger transistor count million vs. The Parhelia series was Matrox ‘s attempt to paryelia to the market after a long hiatus, their first significant effort since the G and G lines had become uncompetitive.
