NVIDIA GeForce 6800 GS Image NVIDIA NV40 A1 Image
The GeForce 6800 GS was a graphics card by NVIDIA, launched in December 2005. Built on the 130 nm process, and based on the NV40 A1 graphics processor, the card supports DirectX 9.0c. The NV40 A1 graphics processor is an average sized chip with a die area of 287 mm² and 222 million transistors. It features 12 pixel shaders and 5 vertex shaders, 12 texture mapping units and 12 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 GDDR3 memory on the card, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 350 MHz, memory is running at 500 MHz.
We recommend the NVIDIA GeForce 6800 GS for gaming with highest details at resolutions up to, and including, 800x600.
Being a single-slot card, the NVIDIA GeForce 6800 GS draws power from 1x Molex power connectors, with power draw not exactly known. Display outputs include: 1x DVI, 1x VGA, 1x S-Video. GeForce 6800 GS is connected to the rest of the system using an AGP 8x interface.
