Retrieved from ” https: This, unfortunately, proved not to be an efficient arrangement in most situations. Due to their equivalent pricing against faster cards, the Parhelia never got a significant hold in the market. As had happened with previous Matrox products, the Parhelia was released just before competing companies released cards that completely outperformed it.

From Wikipedia, the free encyclopedia. The Parhelia processor featured Glyph acceleration, where anti-aliasing of text was accelerated by the hardware. 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”. Later in Parhelia’s life, when DirectX 9 applications were becoming quite prevalent, Matrox acknowledged that the vertex shaders were not Shader Model 2. 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.
This, unfortunately, proved not to be an efficient arrangement in most situations.

The Parhelia remained a p6550 product, and was Matrox’s last major effort to sell into the consumer market. Unlike previous products, it supports Windows Vista Aero acceleration.
Dual link TMDS is supported via external controller connected to the digital mmillennium. 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 JuneMatrox announced the release of M-Series video cards.
Presumably there were several bugs within the Parhelia core that could not be worked around in the drivers. In this case it was the ATI Radeonreleased only a few months later. Some writers believed Parhelia to have a “crippled” triangle-setup engine that starved the rest of the chip in typical 3D rendering tasks . 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 was wasted on invisible house-keeping tasks because the card lacked the ability to predict overdraw or compress z-buffer data, among other inefficiencies.
Released init was best known for its ability to drive three monitors “Surround Gaming” and its Coral Reef tech demo.

However, ATI’s Radeon was released later that year, with a considerably larger transistor count million vs. After the launch of Parhelia, Matrox released Mllenniumwhich supports only bit memory and has only 2 pixel pipelines.

However, within a few months after release, the Parhelia was completely overshadowed by ATI ‘s far faster and fully DirectX 9. 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.
As had happened with previous Matrox products, the Parhelia was released just before competing companies released cards that completely outperformed it. The “Surround Gaming” support allowed the card to drive three monitors creating a unique level gaming immersion.

matroxx 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. However, only 2 displays can be controlled independently. The Parhelia was only competitive with the older Radeon and GeForce 3which typically cost half as much.
