The “Surround Gaming” support allowed the card to drive three monitors creating a unique level gaming immersion.
This page was last edited on 1 Augustat However, within a few months after release, the Parhelia was completely overshadowed by ATI ‘s far faster and fully DirectX 9. P605, ATI’s Radeon was released later that year, with a considerably larger transistor count million vs.
Originally, Matrox planned to produce the “Parhelia 2” successor, codenamed millenniumm. This, unfortunately, proved not to be an efficient arrangement in most situations.
While mlilennium 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. Later in Parhelia’s life, when DirectX 9 applications were becoming quite prevalent, Matrox acknowledged that the vertex shaders were not Shader Model 2.
From Wikipedia, the free encyclopedia. Released init was best known for its ability to drive three monitors “Surround Gaming” and its Coral Reef tech demo. In JuneMatrox announced the release of Millenniu, video cards.
It remained a niche product, while nVidia and ATI control the majority of the discrete graphics chip millsnnium. Unlike previous products, it supports Windows Vista Aero acceleration.
Dual link TMDS is supported via external controller connected to the millenmium interface. 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 this case it was the ATI Radeonreleased only a few months later. The frame buffer is in RGBA As had happened with previous Matrox products, the Parhelia was released just before competing companies released cards that completely outperformed it.

In other projects Wikimedia Commons. 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: Views Read Edit View history.
However, it was all a bit of a moot point because Parhelia’s performance was not adequate to milllennium most DirectX 9-supporting titles well even without more complex shader code weighing the card down. Some writers believed Parhelia to have a “crippled” triangle-setup engine that starved the rest of the chip in typical 3D rendering tasks .
However, only 2 displays can be controlled independently. 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 Millenbium, glyph millemnium, high resolutions, and 16x fragment anti-aliasing. After the launch of Parhelia, Matrox released Mlilenniumwhich 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.

Presumably there were several bugs within millenniu, Parhelia core that could not be worked around in the drivers. Due to their equivalent pricing against faster cards, the Parhelia never got a significant hold in the market. The Parhelia processor featured Glyph acceleration, where anti-aliasing of text was accelerated by the hardware. The “” suffix refers to the bit ring bus. 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 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.
