NVIDIA Quadro4 400 NVS PCI Image NVIDIA NV17 A3 Image
The Quadro4 400 NVS PCI was a professional graphics card by NVIDIA, launched in July 2004. Built on the 150 nm process, and based on the NV17 A3 graphics processor, the card supports DirectX 8.0. The NV17 A3 graphics processor is a relatively small chip with a die area of only 65 mm² and 29 million transistors. Quadro4 400 NVS PCI combines two graphics processors to increase performance. It features 2 pixel shaders and 0 vertex shaders, 4 texture mapping units and 2 ROPs per GPU. 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 per GPU (each GPU manages 64 MB). The GPU is operating at a frequency of 220 MHz, memory is running at 166 MHz.
Being a single-slot card, the NVIDIA Quadro4 400 NVS PCI does not require any additional power connector, its power draw is rated at 18 W maximum. Display outputs include: 2x LFH60. Quadro4 400 NVS PCI is connected to the rest of the system using a PCI interface.
