The Quadro4 900 XGL was a professional graphics card by NVIDIA, launched in February 2002. Built on the 150 nm process, and based on the NV25 A2 graphics processor, in its NV25 GL variant, the card supports DirectX 8.1. The NV25 A2 graphics processor is an average sized chip with a die area of 142 mm² and 63 million transistors. It features 4 pixel shaders and 2 vertex shaders, 8 texture mapping units and 8 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). NVIDIA 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 300 MHz, memory is running at 325 MHz.
Being a single-slot card, the NVIDIA Quadro4 900 XGL does not require any additional power connector, its power draw is not exactly known. Display outputs include: 2x DVI, 1x S-Video. Quadro4 900 XGL is connected to the rest of the system using an AGP 4x interface.
