NVIDIA GeForce 7900 GS Image NVIDIA G71 Image
The GeForce 7900 GS was a performance graphics card by NVIDIA, launched in May 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. 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 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 450 MHz, memory is running at 660 MHz.
We recommend the NVIDIA GeForce 7900 GS for gaming with highest details at resolutions up to, and including, 1280x720.
Being a single-slot card, the NVIDIA GeForce 7900 GS draws power from 1x 6-pin power connectors, 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 PCIe 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.
