Specifications of the NVIDIA GeForce 7900 GS AGP GPU


Released in April 2006, NVIDIA GeForce 7900 GS AGP desktop Graphics Processing Unit makes use of Second Generation CineFX Shading architecture, and is manufactured on 90 nm technological process. The card has 450 MHz graphics clock frequency. It also has 24 pixel shaders, 16 ROPs, together with 20 texture units. The GeForce 7900 GS AGP incorporates 256 MB of GDDR3 memory. Because the memory operates at 660 MHz, and utilizes 256 bit bus, the effective memory bandwidth is 42.24 GB/s. The GPU supports AGP 8x interface, and requires a single motherboard slot. 3D graphics and game performance of the NVIDIA GeForce 7900 GS AGP can be improved if it is paired with another card.

Below you will find more detailed specs of the NVIDIA GeForce 7900 GS AGP GPU.
