NVIDIA GeForce 6800 Ultra AGP

NVIDIA GeForce 6800 Ultra AGP Image NVIDIA NV40 Image
The GeForce 6800 Ultra AGP was a graphics card by NVIDIA, launched in April 2004. Built on the 130 nm process, and based on the NV40 graphics processor, the card supports DirectX 9.0c. The NV40 graphics processor is an average sized chip with a die area of 287 mm² and 125 million transistors. It features 16 pixel shaders and 6 vertex shaders, 16 texture mapping units and 16 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 256 MB GDDR3 memory on the card, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 400 MHz, memory is running at 550 MHz.
We recommend the NVIDIA GeForce 6800 Ultra AGP for gaming with highest details at resolutions up to, and including, 1024x768.
Being a single-slot card, its power draw is not exactly known. Display outputs include: 2x DVI, 1x S-Video. GeForce 6800 Ultra AGP is connected to the rest of the system using an AGP 8x interface.
