Matrox Parhelia 128 MB Image
The Parhelia 128 MB was a graphics card by Matrox, launched in January 2001. Built on the 150 nm process, and based on the Parhelia-512 graphics processor, the card supports DirectX 8.1. It features 4 pixel shaders and 4 vertex shaders, 4 texture mapping units and 4 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 256-bit memory interface. The GPU is operating at a frequency of 220 MHz, memory is running at 275 MHz.
Being a single-slot card, its power draw is not exactly known. Parhelia 128 MB is connected to the rest of the system using an AGP 8x interface.
