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. In other projects Wikimedia Commons. Originally, Matrox planned to produce the “Parhelia 2” successor, codenamed “Pitou”.

Some writers believed Parhelia to have a “crippled” triangle-setup engine that starved the rest of the chip in typical 3D rendering tasks [1].

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.

However, ATI’s Radeon was released later that year, with a considerably larger transistor count million vs. 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.

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

The Parhelia remained a niche product, and was Matrox’s last major effort to sell into the matroz market. Presumably there were several bugs within the Parhelia core that could not be worked around in the drivers. Later in Parhelia’s life, when DirectX 9 applications were becoming quite prevalent, Matrox acknowledged that the vertex shaders were not Shader Model 2.

In this case it was the ATI Radeonreleased only a few months pfi.
