The GeForce 6600 GT Dual was a graphics card by NVIDIA, launched on August 12th, 2004. Built on the 110 nm process, and based on the NV43 graphics processor, the card supports DirectX 9.0c. Since GeForce 6600 GT Dual does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. The NV43 graphics processor is an average sized chip with a die area of 154 mm² and 146 million transistors. GeForce 6600 GT Dual combines two graphics processors to increase performance. It features 8 pixel shaders and 3 vertex shaders, 8 texture mapping units, and 4 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 paired 256 MB GDDR3 memory with the GeForce 6600 GT Dual, which are connected using a 128-bit memory interface per GPU (each GPU manages 128 MB). The GPU is operating at a frequency of 500 MHz, memory is running at 560 MHz.
Being a single-slot card, the NVIDIA GeForce 6600 GT Dual draws power from 1x 6-pin power connector, with power draw not exactly known. Display outputs include: 1x DVI, 1x VGA, 1x S-Video. GeForce 6600 GT Dual is connected to the rest of the system using a PCI-Express 1.0 x16 interface.
