Matrox Parhelia-LX Image
The Parhelia-LX was a graphics card by Matrox, launched in January 2002. Built on the 150 nm process, and based on the Parhelia-LX graphics processor, the card supports DirectX 8.1. It features 2 pixel shaders and 2 vertex shaders, 4 texture mapping units and 2 ROPs. Due to the lack of unified shaders you will not be able to run recent games at all (which require unified shader/DX10+ support). Matrox has placed 128 MB DDR memory on the card, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 250 MHz, memory is running at 250 MHz.
Being a single-slot card, its power draw is not exactly known. Display outputs include: 2x DVI. Parhelia-LX is connected to the rest of the system using an AGP 8x interface.
