NVIDIA GeForce 6600 GT Dual Image NVIDIA NV43 A2 Image
The GeForce 6600 GT Dual was a graphics card by NVIDIA, launched in August 2004. Built on the 110 nm process, and based on the NV43 A2 graphics processor, the card supports DirectX 9.0c. The NV43 A2 graphics processor is an average sized chip with a die area of 150 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 placed 256 MB GDDR3 memory on the card, which are connected using a 128-bit memory interface per GPU (each GPU manages 128 MB). The GPU is operating at a frequency of 450 MHz, memory is running at 500 MHz.
Being a single-slot card, the NVIDIA GeForce 6600 GT Dual draws power from 1x 6-pin power connectors, 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 PCIe 1.0 x16 interface.
