NVIDIA GeForce 6800 GT Dual Image NVIDIA NV45 Image
The GeForce 6800 GT Dual was a graphics card by NVIDIA, launched in June 2004. Built on the 130 nm process, and based on the NV45 graphics processor, the card supports DirectX 9.0c. The NV45 graphics processor is an average sized chip with a die area of 287 mm² and 222 million transistors. GeForce 6800 GT Dual combines two graphics processors to increase performance. It features 16 pixel shaders and 6 vertex shaders, 16 texture mapping units and 16 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 512 MB GDDR3 memory on the card, which are connected using a 256-bit memory interface per GPU (each GPU manages 256 MB). The GPU is operating at a frequency of 350 MHz, memory is running at 500 MHz.
We recommend the NVIDIA GeForce 6800 GT Dual for gaming with highest details at resolutions up to, and including, 1280x720.
Being a dual-slot card, the NVIDIA GeForce 6800 GT Dual draws power from 1x 6-pin power connectors, with power draw not exactly known. Display outputs include: 2x DVI, 1x S-Video. GeForce 6800 GT Dual is connected to the rest of the system using a PCIe 1.0 x16 interface.
