ATI Radeon IGP 320M Image
The Radeon IGP 320M was a mobile integrated graphics solution by ATI, launched in October 2002. Built on the 180 nm process, and based on the RS320M graphics processor, the card supports DirectX 7.0. It features 1 pixel shaders and 0 vertex shaders, 1 texture mapping units and 1 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). The GPU is operating at a frequency of 160 MHz.
Its power draw is not exactly known. Radeon IGP 320M is connected to the rest of the system using an AGP 4x interface.
