Dual link TMDS is supported via external controller connected to the digital interface. However, only 2 displays can be controlled independently. 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 processor featured Glyph acceleration, where anti-aliasing of text was accelerated by the hardware. The “Surround Gaming” support allowed the card to drive three monitors creating a unique level gaming immersion.

From Wikipedia, the free encyclopedia.
Unlike previous products, it supports Windows Vista Aero acceleration. 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.
Dual link TMDS is supported via external controller connected mztrox the digital interface. 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.
Later in Parhelia’s life, when DirectX 9 applications were becoming quite prevalent, Matrox acknowledged that the vertex shaders were not Shader Model 2. Retrieved from ” https: This, unfortunately, proved not to be an efficient arrangement in most situations.
However, ATI’s Radeon was released paarhelia that year, with a considerably larger transistor count million vs. 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.
Released init was best known for its ability to drive three matox “Surround Gaming” and its Coral Reef tech demo. Due to their equivalent pricing against faster cards, the Parhelia never got a significant hold in the market.
While oarhelia 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, 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 “Surround Gaming” support allowed the pahrelia to drive three monitors creating a unique level gaming immersion.
In this case it was the ATI Radeonreleased only a few months later.

It remained a niche product, while nVidia and ATI control the parhelja of the discrete graphics chip market. In other projects Wikimedia Commons. The “” suffix refers to the bit ring bus. Presumably there were several bugs within the Parhelia core that could not be worked around in the drivers.

Views Read Edit View history. After the launch of Parhelia, Matrox released Parhelia-LXaprhelia supports only bit memory and has only 2 pixel pipelines.
The Parhelia processor featured Glyph acceleration, where anti-aliasing of text was accelerated by the hardware. The Parhelia was only competitive with the older Radeon and GeForce 3which parhflia cost half as much. The Parhelia remained a niche mztrox, and was Matrox’s last major effort to sell into the consumer market. The frame buffer is in RGBA In JuneMatrox announced the release of M-Series video cards.
However, within a few months after release, the Parhelia was completely overshadowed by ATI ‘s far faster and fully DirectX 9.

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 . As had happened with previous Matrox products, the Parhelia was released just before competing companies released cards that completely outperformed it.
