The GeForce 7800 GT Dual was an enthusiast-class graphics card by NVIDIA, launched on August 11th, 2005. Built on the 110 nm process, and based on the G70 graphics processor, in its GF-7800-GT-A2 variant, the card supports DirectX 9.0c. Since GeForce 7800 GT Dual does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. The G70 graphics processor is a large chip with a die area of 333 mm² and 302 million transistors. GeForce 7800 GT Dual combines two graphics processors to increase performance. It features 20 pixel shaders and 7 vertex shaders, 20 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 paired 512 MB GDDR3 memory with the GeForce 7800 GT Dual, which are connected using a 256-bit memory interface per GPU (each GPU manages 256 MB). The GPU is operating at a frequency of 400 MHz, memory is running at 500 MHz.
Being a dual-slot card, the NVIDIA GeForce 7800 GT Dual draws power from 1x 6-pin power connector, with power draw rated at 120 W maximum. Display outputs include: 2x DVI, 2x VGA, 1x S-Video. GeForce 7800 GT Dual is connected to the rest of the system using a PCI-Express 1.0 x16 interface. Its price at launch was 799 US Dollars.
