NVIDIA GeForce 7900 GX2 Image NVIDIA G71 Image
The GeForce 7900 GX2 was a high-end graphics card by NVIDIA, launched in April 2006. Built on the 90 nm process, and based on the G71 graphics processor, 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. GeForce 7900 GX2 combines two graphics processors to increase performance. It features 24 pixel shaders and 8 vertex shaders, 24 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 placed 1,024 MB GDDR3 memory on the card, which are connected using a 256-bit memory interface per GPU (each GPU manages 512 MB). The GPU is operating at a frequency of 500 MHz, memory is running at 600 MHz.
We recommend the NVIDIA GeForce 7900 GX2 for gaming with highest details at resolutions up to, and including, 1680x1050.
Being a dual-slot card, the NVIDIA GeForce 7900 GX2 draws power from 2x 6-pin power connectors, with power draw not exactly known. Display outputs include: 2x DVI, 1x S-Video. GeForce 7900 GX2 is connected to the rest of the system using a PCIe 1.0 x16 interface. The card measures 305 mm in length, and features a dual-slot cooling solution. Its price at launch was 599 US Dollars.
