MATROX PARHELIA 256 DRIVER

It remained a niche product, while nVidia and ATI control the majority of the discrete graphics chip market. Unlike previous products, it supports Windows Vista Aero acceleration. 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 this case it was the ATI Radeon , released only a few months later. The “” suffix refers to the bit ring bus. After the launch of Parhelia, Matrox released Parhelia-LX , which supports only bit memory and has only 2 pixel pipelines.

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. 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. By using this site, you agree to the Terms of Use and Privacy Policy. The Parhelia processor featured Glyph acceleration, where anti-aliasing of text was accelerated by the hardware.

This, unfortunately, proved not to be an efficient arrangement in most situations.

Views Read Edit View history. The Parhelia was only competitive with the pahrelia Radeon and GeForce 3which typically cost half as much. However, only 2 displays can be controlled independently.

Unlike previous products, it supports Windows Vista Aero acceleration. The “” suffix refers to the bit ring bus.

Mahrox, 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 parheila code weighing the card down. 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.

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

In this case it was the ATI Radeonreleased only a few months later. After the launch of Parhelia, Matrox released Parhelia-LXwhich 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. The Parhelia was the first GPU by Matrox to be equipped with pahelia bit memory bus, giving it an advantage over other cards of the time in the area of memory bandwidth. Released init was best known for its ability to drive three monitors “Surround Gaming” and its Coral Reef tech demo.
