Specifications of the NVIDIA GeForce 7900 GX2 GPU


NVIDIA GeForce 7900 GX2 is a desktop Graphics Processing Unit, that utilizes Second Generation CineFX Shading architecture and is built on 90 nm technology. The GPU was released in April 2006. The cards graphics frequency is 500 MHz. It also has 48 pixel shaders, 48 texture units, along with 32 ROPs. The GeForce 7900 GX2 embeds 1 GB of GDDR3 memory. Because the memory operates at 600 MHz, and uses 512 bit bus, the effective memory bandwidth is 76.8 GB/s. The GPU supports PCI Express 1.0 interface, and needs 2 motherboard slots. To boost NVIDIA GeForce 7900 GX2 3D graphics and game performance, it can be paired with another card in SLI mode.
