The GeForce 6800 Ultra was a graphics card by NVIDIA, launched in April 2004. Built on the 130 nm process, and based on the NV40 graphics processor, in its 6800 Ultra variant, the card supports DirectX 9.0c. Since GeForce 6800 Ultra does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. The NV40 graphics processor is an average sized chip with a die area of 287 mm² and 222 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 paired 256 MB GDDR3 memory with the GeForce 6800 Ultra, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 425 MHz, memory is running at 550 MHz.
Being a single-slot card, the NVIDIA GeForce 6800 Ultra draws power from 2x Molex power connectors, with power draw not exactly known. Display outputs include: 2x DVI, 1x S-Video. GeForce 6800 Ultra is connected to the rest of the system using an AGP 8x interface. The card measures 216 mm in length, and features a single-slot cooling solution.
