The GeForce 7950 GX2 was a high-end graphics card by NVIDIA, launched on June 5th, 2006. Built on the 90 nm process, and based on the G71 graphics processor, in its G71-D-H-N-A2 variant, the card supports DirectX 9.0c. Since GeForce 7950 GX2 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. GeForce 7950 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 paired 1,024 MB GDDR3 memory with the GeForce 7950 GX2, 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.
Being a dual-slot card, the NVIDIA GeForce 7950 GX2 draws power from 1x 6-pin power connector, with power draw rated at 110 W maximum. Display outputs include: 2x DVI, 1x S-Video. GeForce 7950 GX2 is connected to the rest of the system using a PCI-Express 1.0 x16 interface. The card measures 229 mm in length, 111 mm in width, and features a dual-slot cooling solution. Its price at launch was 599 US Dollars.
