The GeForce 7900 GS was a performance-segment graphics card by NVIDIA, launched on May 1st, 2006. Built on the 90 nm process, and based on the G71 graphics processor, in its G71-N-A2 variant, the card supports DirectX 9.0c. Since GeForce 7900 GS does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. The G71 graphics processor is an average sized chip with a die area of 196 mm² and 278 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 paired 256 MB GDDR3 memory with the GeForce 7900 GS, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 450 MHz, memory is running at 660 MHz.
Being a single-slot card, the NVIDIA GeForce 7900 GS draws power from 1x 6-pin power connector, with power draw rated at 49 W maximum. Display outputs include: 2x DVI, 1x S-Video. GeForce 7900 GS is connected to the rest of the system using a PCI-Express 1.0 x16 interface. The card measures 198 mm in length, and features a single-slot cooling solution. Its price at launch was 259 US Dollars.
