The GeForce 7800 GT was a high-end graphics card by NVIDIA, launched in August 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. The G70 graphics processor is a large chip with a die area of 333 mm² and 302 million transistors. It features 20 pixel shaders and 7 vertex shaders, 20 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 placed 256 MB GDDR3 memory on the card, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 400 MHz, memory is running at 500 MHz.
Being a single-slot card, the NVIDIA GeForce 7800 GT draws power from 1x 6-pin power connectors, with power draw rated at 65 W maximum. Display outputs include: 2x DVI, 1x S-Video. GeForce 7800 GT is connected to the rest of the system using a PCI-Express 1.0 x16 interface. The card measures 226 mm in length, and features a single-slot cooling solution. Its price at launch was 449 US Dollars.
