The GeForce 7900 GTX was a graphics card by NVIDIA, launched on March 9th, 2006. Built on the 90 nm process, and based on the G71 graphics processor, in its G71-U-N-A2 variant, the card supports DirectX 9.0c. Since GeForce 7900 GTX 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 24 pixel shaders and 8 vertex shaders, 24 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 512 MB GDDR3 memory with the GeForce 7900 GTX, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 650 MHz, memory is running at 800 MHz.
Being a dual-slot card, the NVIDIA GeForce 7900 GTX draws power from 1x 6-pin power connector, with power draw rated at 84 W maximum. Display outputs include: 2x DVI, 1x S-Video. GeForce 7900 GTX is connected to the rest of the system using a PCI-Express 1.0 x16 interface.
