This mn was last edited on 1 Augustat 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. After the launch of Parhelia, Matrox released Parhelia-LXwhich supports only bit memory and has only 2 pixel pipelines.

To further improve analog image quality, 5th order low-pass filters are used. In JuneMatrox announced the release of M-Series video cards.

The Parhelia remained a niche product, parheliaa was Matrox’s last major effort to sell into the consumer market. Originally, Matrox planned to produce the “Parhelia 2” successor, codenamed “Pitou”. 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.

The Parhelia processor featured Glyph acceleration, where anti-aliasing of text was accelerated by the hardware. It remained a niche product, while nVidia and ATI control the majority of the discrete graphics chip market. Unlike previous products, it supports Windows Vista Aero acceleration.

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

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 Parhelia series was Matrox ‘s attempt to return to the market after a long hiatus, their first significant effort parnelia the G and G matfox had become uncompetitive.

From Wikipedia, the free encyclopedia. However, within a few months after release, the Parhelia was completely overshadowed by ATI ‘s far faster and fully DirectX 9.

The Parhelia was the first GPU by Matrox to be equipped with a bit memory bus, giving it matrlx advantage over other cards of the time in the area of memory bandwidth.

The “Surround Gaming” support allowed the card to drive three monitors creating a unique level gaming immersion. This, unfortunately, proved not to be an efficient arrangement in most situations. The pargelia buffer is in RGBA Some writers believed Parhelia to have a “crippled” triangle-setup engine that starved the rest of the chip in typical 3D rendering tasks [1]. Due to their equivalent pricing against faster cards, the Parhelia never got a significant hold in the market.


The Parhelia was only competitive with the older Radeon and GeForce 3which typically cost half as much. Views Read Edit View history.

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.

Later in Parhelia’s life, when DirectX 9 applications were becoming quite prevalent, Matrox acknowledged that the vertex shaders were not Shader Model 2. As had happened with previous Matrox products, the Parhelia was released just before competing companies released cards that completely outperformed it. Dual link TMDS is supported via external controller connected to the digital interface.
