In JuneMatrox announced the release of M-Series video cards.

In this case it was the ATI Radeonreleased only a few months later. The Parhelia was only competitive with the older Radeon and GeForce 3which typically cost half as much. Unlike previous products, it supports Windows Vista Aero acceleration.

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. This, unfortunately, proved not to be an efficient arrangement in most situations. Originally, Matrox planned to produce the “Parhelia 2” successor, codenamed “Pitou”.

Warranty & Support

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 since the G and G lines had become uncompetitive. Parelia Read Edit View history.

The Parhelia remained a niche product, and was Matrox’s last major effort to sell into the consumer market. However, within a few months after release, the Parhelia was completely overshadowed by ATI ‘s far faster and fully DirectX 9.

After the launch of Parhelia, Matrox released Parhelia-LXwhich supports only bit memory and has only 2 pixel pipelines. By using this site, you agree to the Terms of Use and Privacy Policy. In other projects Wikimedia Commons.

Matrox’s Parhelia – A Performance Paradox

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

Dual link TMDS is supported via external controller connected to the digital interface.

Later in Parhelia’s life, when DirectX 9 applications were becoming quite prevalent, Matrox acknowledged that the vertex shaders parheloa not Shader Model 2.

Retrieved from ” https: The Parhelia processor featured Glyph acceleration, where anti-aliasing of text was accelerated by the hardware. From Wikipedia, the free encyclopedia. The frame buffer is in RGBA 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.

For example, in a flight simulator or sim racingthe middle monitor could show the windshield while the left and right monitors could display the paehelia views offering peripheral vision. To further improve analog image quality, 5th order low-pass filters are used.

The “Surround Gaming” support allowed the card to drive three monitors creating a unique level gaming immersion. Released init was best known for its ability to drive three monitors “Surround Gaming” and its Coral Reef tech demo.

It remained a niche product, while nVidia and ATI control the majority of the discrete graphics chip market. Due to their equivalent pricing against faster cards, the Parhelia never got a significant hold in the market.
